5 SCons - a software construction tool
10 RELEASE 1.3.0 - Tue, 23 Mar 2010 21:44:19 -0400
14 - Update man page and documentation.
16 From William Deegan (plus minor patch from Gary Oberbrunner):
18 - Support Visual Studio 8.0 Express
20 RELEASE 1.2.0.d20100306 - Sat, 06 Mar 2010 16:18:33 -0800
24 - Fix typos in the man page.
26 From Gottfried Ganssauge:
28 - Support execution when SCons is installed via easy_install.
32 - Make the messages for Configure checks of compilers consistent.
34 - Issue an error message if a BUILDERS entry is not a Builder
35 object or a callable wrapper.
39 - Update tex builder to handle the case where a \input{foo}
40 command tries to work with a directory named foo instead of the
41 file foo.tex. The builder now ignores a directory and continues
42 searching to find the correct file. Thanks to Lennart Sauerbeck
43 for the test case and initial patch
45 Also allow the \include of files in subdirectories when variantDir
46 is used with duplicate=0. Previously latex would crash since
47 the directory in which the .aux file is written was not created.
48 Thanks to Stefan Hepp for finding this and part of the solution.
51 - Patches to fix some issues using MS SDK V7.0
54 - Lots of testing and minor patches to handle mixed MS VC and SDK
55 installations, as well as having only the SDK installed.
58 RELEASE 1.2.0.d20100117 - Sun, 17 Jan 2010 14:26:59 -0800
61 - Fixed temp filename race condition on Windows with long cmd lines.
63 From David Cournapeau:
64 - Fixed tryRun when sconf directory is in a variant dir.
65 - Do not add -fPIC for ifort tool on non-posix platforms (darwin and
67 - Fix bug 2294 (spurious CheckCC failures).
68 - Fix scons bootstrap process on windows 64 (wrong wininst name)
71 - Final merge from vs_revamp branch to main
73 - Added definition and usage of HOST_OS, HOST_ARCH, TARGET_OS,
74 TARGET_ARCH, currently only defined/used by Visual Studio
75 Compilers. This will be rolled out to other platforms/tools
78 - Add check for python >= 3.0.0 and exit gracefully.
79 For 1.3 python >= 1.5.2 and < 3.0.0 are supported
81 - Fix bug 1944 - Handle non-existent .i file in swig emitter, previously
82 it would crash with an IOError exception. Now it will try to make an
83 educated guess on the module name based on the filename.
85 From Lukas Erlinghagen:
87 - Have AddOption() remove variables from the list of
88 seen-but-unknown variables (which are reported later).
90 - An option name and aliases can now be specified as a tuple.
98 - use "is/is not" in comparisons with None instead of "==" or "!=".
102 - Avoid adding -gphobos to a command line multiple times
103 when initializing use of the DMD compiler.
107 - Sugguested HOST/TARGET OS/ARCH separation.
111 - Fix the -n option when used with VariantDir(duplicate=1)
112 and the variant directory doesn't already exist.
114 - Fix scanning of Unicode files for both UTF-16 endian flavors.
116 - Fix a TypeError on #include of file names with Unicode characters.
118 - Fix an exception if a null command-line argument is passed in.
120 - Evaluate Requires() prerequisites before a Node's direct children
121 (sources and dependencies).
125 - Remove redundant __metaclass__ initializations in Environment.py.
127 - Correct the documentation of text returned by sconf.Result().
129 - Document that filenames with '.' as the first character are
130 ignored by Glob() by default (matching UNIX glob semantics).
132 - Fix SWIG testing infrastructure to work on Mac OS X.
134 - Restructure a test that occasionally hung so that the test would
135 detect when it was stuck and fail instead.
139 From Gary Oberbrunner:
141 - When reporting a target that SCons doesn't know how to make,
142 specify whether it's a File, Dir, etc.
146 - Fix use of $SWIGOUTDIR when generating Python wrappers.
148 - Add $SWIGDIRECTORSUFFIX and $SWIGVERSION construction variables.
152 - Add -recorder flag to Latex commands and updated internals to
153 use the output to find files TeX creates. This allows the MiKTeX
154 installations to find the created files
156 - Notify user of Latex errors that would get buried in the
159 - Remove LATEXSUFFIXES from environments that don't initialize Tex.
161 - Add support for the glosaaries package for glossaries and acronyms
163 - Fix problem that pdftex, latex, and pdflatex tools by themselves did
164 not create the actions for bibtex, makeindex,... by creating them
165 and other environment settings in one routine called by all four
168 - Fix problem with filenames of sideeffects when the user changes
169 the name of the output file from the latex default
171 - Add scanning of files included in Latex by means of \lstinputlisting{}
172 Patch from Stefan Hepp.
174 - Change command line for epstopdf to use --outfile= instead of -o
175 since this works on all platforms.
176 Patch from Stefan Hepp.
178 - Change scanner to properly search for included file from the
179 directory of the main file instead of the file it is included from.
180 Also update the emitter to add the .aux file associated with
181 \include{filename} commands. This makes sure the required directories
182 if any are created for variantdir cases.
183 Half of the patch from Stefan Hepp.
185 RELEASE 1.2.0.d20090223 - Mon, 23 Feb 2009 08:41:06 -0800
187 From Stanislav Baranov:
189 - Make suffix-matching for scanners case-insensitive on Windows.
191 From David Cournapeau:

488 - Fix VariantDir duplication of #included files in subdirectories.
492 - Reduce memory usage when a directory is used as a dependency of
493 another Node (such as an Alias) by returning a concatenation

499 - Invalidate cached Node information (such as the contenst returned
500 by the get_contents() method) when calling actions with Execute().
502 - Avoid object reference cycles from frame objects.
504 - Reduce memory usage from Null Executor objects.
506 - Compute MD5 checksums of large files without reading the entire
507 file contents into memory. Add a new --md5-chunksize option to
508 control the size of each chunk read into memory.
512 - Fix the ability of the add_src_builder() method to add a new
513 source builder to any other builder.
515 - Avoid an infinite loop on non-Windows systems trying to find the

520 no version number) after "scons-local-{VERSION}".
524 - Fix the user's ability to interrupt the TeX build chain.
526 - Fix the TeX builder's allowing the user to specify the target name,
527 instead of always using its default output name based on the source.
529 - Iterate building TeX output files until all warning are gone
530 and the auxiliary files stop changing, or until we reach the
531 (configurable) maximum number of retries.
533 - Add TeX scanner support for: glossaries, nomenclatures, lists of
534 figures, lists of tables, hyperref and beamer.
536 - Use the $BIBINPUTS, $BSTINPUTS, $TEXINPUTS and $TEXPICTS construction
537 variables as search paths for the relevant types of input file.

742 mistakenly reporting failures after any individual build fails.
744 - Fix calling File() as a File object method in some circumstances.
746 - Fix setup.py installation on Mac OS X so SCons gets installed

797 "import SCons.Options.{Bool,Enum,List,Package,Path}Option" submodules.
799 - Fix searching for implicit dependencies when an Entry Node shows up
800 in the search path list.
804 - Fix expansion of $FORTRANMODDIR in the default Fortran command line(s)
805 when it's set to something like ${TARGET.dir}.
809 RELEASE 0.98.2 - Sun, 20 Apr 2008 23:38:56 -0700
813 - Fix a bug in Fortran suffix computation that would cause SCons to
814 run out of memory on Windows systems.
816 - Fix being able to specify --interactive mode command lines with
817 \ (backslash) path name separators on Windows.
819 From Gary Oberbrunner:
821 - Document Glob() in the User's Guide.
825 RELEASE 0.98.1 - Fri, 18 Apr 2008 19:11:58 -0700
829 - Speed up the SCons.Util.to_string*() functions.
831 - Optimize various Node intialization and calculations.
833 - Optimize Executor scanning code.
835 - Optimize Taskmaster execution, including dependency-cycle checking.
837 - Fix the --debug=stree option so it prints its tree once, not twice.
841 - Fix the ability to use LoadableModule() under MinGW.
843 From David Cournapeau:
845 - Various missing Fortran-related construction variables have been added.
847 - SCons now uses the program specified in the $FORTRAN construction
848 variable to link Fortran object files.
850 - Fortran compilers on Linux (Intel, g77 and gfortran) now add the -fPIC
851 option by default when compilling shared objects.
853 - New 'sunf77', 'sunf90' and 'sunf95' Tool modules have been added to
854 support Sun Fortran compilers. On Solaris, the Sun Fortran compilers
855 are used in preference to other compilers by default.
857 - Fortran support now uses gfortran in preference to g77.
859 - Fortran file suffixes are now configurable through the
860 $F77FILESUFFIXES, $F90FILESUFFIXES, $F95FILESUFFIXES and
861 $FORTRANFILESUFFIXES variables.
865 - Make the -d, -e, -w and --no-print-directory options "Ignored for
866 compatibility." (We're not going to implement them.)
868 - Fix a serious inefficiency in how SCons checks for whether any source
869 files are missing when a Builder call creates many targets from many
872 - In Java projects, make the target .class files depend only on the
873 specific source .java files where the individual classes are defined.
875 - Don't store duplicate source file entries in the .sconsign file so
876 we don't endlessly rebuild the target(s) for no reason.
878 - Add a Variables object as the first step towards deprecating the
879 Options object name. Similarly, add BoolVariable(), EnumVariable(),
880 ListVariable(), PackageVariable() and PathVariable() functions
881 as first steps towards replacing BoolOption(), EnumOption(),
882 ListOption(), PackageOption() and PathOption().
884 - Change the options= keyword argument to the Environment() function
885 to variables=, to avoid confusion with SCons command-line options.
886 Continue supporting the options= keyword for backwards compatibility.

923 - Improve support for non-standard library prefixes and suffixes by
924 stripping all prefixes/suffixes from file name string as appropriate.
926 - Reduce the default stack size for -j worker threads to 256 Kbytes.

931 and no /opt/intel_cc_* directories are found.
933 - Improve using Python functions as actions by incorporating into
934 a FunctionAction's signature:
935 - literal values referenced by the byte code.

944 - Add support for the Intel C compiler on Mac OS X.
946 - Speed up reading SConscript files by about 20% (for some
947 configurations) by: 1) optimizing the SCons.Util.is_*() and
948 SCons.Util.flatten() functions; 2) avoiding unnecessary os.stat()
949 calls by using a File's .suffix attribute directly instead of
952 From Jérôme Berger:
954 - Have the D language scanner search for .di files as well as .d files.
956 - Add a find_include_names() method to the Scanner.Classic class to
957 abstract out how included names can be generated by subclasses.
959 - Allow the D language scanner to detect multiple modules imported by

970 From David Cournapeau:
972 - Add a CheckDeclaration() call to configure contexts.
974 - Improve the CheckTypeSize() code.

991 - Improve the performance of our type-checking by using isinstance()
992 with new-style classes.
994 - Fix #include (and other $*PATH variables searches) of files with
995 absolute path names. Don't die if they don't exist (due to being
996 #ifdef'ed out or the like).
998 - Fix --interactive mode when Default(None) is used.
1000 - Fix --debug=memoizer to work around a bug in base Python 2.2 metaclass
1001 initialization (by just not allowing Memoization in Python versions

1005 log files that contain no results specified by the --which option.
1007 - Fix the max Y of vertical bars drawn by "scons-time --fmt=gnuplot".
1009 - On Mac OS X, account for the fact that the header file generated

1017 - Fix use of file names containing strings of multiple spaces when
1018 using ActionFactory instances like the Copy() or Move() function.
1020 - Fix a 0.97 regression when using a variable expansion (like
1021 $OBJSUFFIX) in a source file name to a builder with attached source
1022 builders that match suffix (like Program()+Object()).
1024 - Have the Java parser recognize generics (surrounded by angle brackets)
1025 so they don't interfere with identifying anonymous inner classes.
1027 - Avoid an infinite loop when trying to use saved copies of the
1028 env.Install() or env.InstallAs() after replacing the method

1060 - Have the Copy() action factory preserve file modes and times
1061 when copying individual files.

1072 - Add the parse_flags option when creating Environments
1074 From Gary Oberbrunner:
1076 - Make File(), Dir() and Entry() return a list of Nodes when passed
1077 a list of names, instead of trying to make a string from the name
1078 list and making a Node from that string.
1080 - Fix the ability to build an Alias in --interactive mode.
1082 - Fix the ability to hash the contents of actions for nested Python
1083 functions on Python versions where the inability to pickle them

1130 - Fix occasional spurious rebuilds and inefficiency when using
1131 --implicit-cache and Builders that produce multiple targets.
1133 - Allow SCons to not have to know about the builders of generated

1135 SConscript files to be ignored for smaller builds.
1137 From David Cournapeau:
1139 - Add a CheckTypeSize() call to configure contexts.
1143 - Make the "contents" of Alias Nodes a concatenation of the children's
1144 content signatures (MD5 checksums), not a concatenation of the
1145 children's contents, to avoid using large amounts of memory during
1146 signature calculation.
1150 - Fix a lot of typos in the man page and User's Guide.
1152 From Geoffrey Irving:
1154 - Speed up conversion of paths in .sconsign files to File or Dir Nodes.
1158 - Add an Options.UnknownOptions() method that returns any settings
1159 (from the command line, or whatever dictionary was passed in)
1160 that aren't known to the Options object.
1162 - Add a Glob() function.
1164 - When removing targets with the -c option, use the absolute path (to
1165 avoid problems interpreting BuildDir() when the top-level directory
1166 is the source directory).
1168 - Fix problems with Install() and InstallAs() when called through a
1169 clone (of a clone, ...) of a cloned construction environment.
1171 - When executing a file containing Options() settings, add the file's
1172 directory to sys.path (so modules can be imported from there) and
1173 explicity set __name__ to the name of the file so the statement's
1174 in the file can deduce the location if they need to.
1176 - Fix an O(n^2) performance problem when adding sources to a target
1177 through calls to a multi Builder (including Aliases).
1179 - Redefine the $WINDOWSPROGMANIFESTSUFFIX and
1180 $WINDOWSSHLIBMANIFESTSUFFIX variables so they pick up changes to
1181 the underlying $SHLIBSUFFIX and $PROGSUFFIX variables.
1183 - Add a GetBuildFailures() function that can be called from functions
1184 registered with the Python atexit module to print summary information
1185 about any failures encountered while building.
1187 - Return a NodeList object, not a Python list, when a single_source
1188 Builder like Object() is called with more than one file.
1190 - When searching for implicit dependency files in the directories
1191 in a $*PATH list, don't create Dir Nodes for directories that
1192 don't actually exist on-disk.
1194 - Add a Requires() function to allow the specification of order-only
1195 prerequisites, which will be updated before specified "downstream"
1196 targets but which don't actually cause the target to be rebuilt.
1198 - Restore the FS.{Dir,File,Entry}.rel_path() method.
1200 - Make the default behavior of {Source,Target}Signatures('timestamp')
1201 be equivalent to 'timestamp-match', not 'timestamp-newer'.
1203 - Fix use of CacheDir with Decider('timestamp-newer') by updating
1204 the modification time when copying files from the cache.
1206 - Fix random issues with parallel (-j) builds on Windows when Python
1207 holds open file handles (especially for SCons temporary files,
1208 or targets built by Python function actions) across process creation.
1210 From Maxim Kartashev:
1212 - Fix test scripts when run on Solaris.
1214 From Gary Oberbrunner:

1231 - Move the documentation of Install() and InstallAs() from the list
1232 of functions to the list of Builders (now that they're implemented
1235 - Allow env.CacheDir() to be set per construction environment. The
1236 global CacheDir() function now sets an overridable global default.
1238 - Add an env.Decider() method and a Node.Decider() method that allow
1239 flexible specification of an arbitrary function to decide if a given
1240 dependency has changed since the last time a target was built.
1242 - Don't execute Configure actions (while reading SConscript files)
1243 when cleaning (-c) or getting help (-h or -H).
1245 - Add to each target an implicit dependency on the external command(s)
1246 used to build the target, as found by searching env['ENV']['PATH']
1247 for the first argument on each executed command line.
1249 - Add support for a $IMPLICIT_COMMAND_DEPENDENCIES construction
1250 variabe that can be used to disable the automatic implicit
1251 dependency on executed commands.
1253 - Add an "ensure_suffix" keyword to Builder() definitions that, when
1254 true, will add the configured suffix to the targets even if it looks
1255 like they already have a different suffix.
1257 - Add a Progress() function that allows for calling a function or string
1258 (or list of strings) to display progress while walking the DAG.
1260 - Allow ParseConfig(), MergeFlags() and ParseFlags() to handle output
1261 from a *config command with quoted path names that contain spaces.
1263 - Make the Return() function stop processing the SConscript file and
1264 return immediately. Add a "stop=" keyword argument that can be set
1265 to False to preserve the old behavior.
1267 - Fix use of exitstatfunc on an Action.
1269 - Introduce all man page function examples with "Example:" or "Examples:".
1271 - When a file gets added to a directory, make sure the directory gets
1272 re-scanned for the new implicit dependency.
1274 - Fix handling a file that's specified multiple times in a target
1275 list so that it doesn't cause dependent Nodes to "disappear" from
1276 the dependency graph walk.
1280 - Avoid race conditions with same-named files and directory creation
1281 when pushing copies of files to CacheDir().
1285 - Handle $ in Java class names.
1287 From Gary Oberbrunner:
1289 - Add support for the Intel C compiler on Windows64.
1291 - On SGI IRIX, have $SHCXX use $CXX by default (like other platforms).
1295 - When Cloning a construction environment, set any variables before
1296 applying tools (so the tool module can access the configured settings)
1297 and re-set them after (so they end up matching what the user set).
1299 From Matthias Troffaes:
1301 - Make sure extra auxiliary files generated by some LaTeX packages
1302 and not ending in .aux also get deleted by scons -c.
1306 - Add a $JAVABOOTCLASSPATH variable for directories to be passed to the
1307 javac -bootclasspath option.
1309 From Christoph Wiedemann:
1311 - Add implicit dependencies on the commands used to build a target.
1316 RELEASE 0.97.0d20070809 - Fri, 10 Aug 2007 10:51:27 -0500
1318 From Lars Albertsson:
1320 - Don't error if a #include line happens to match a directory
1321 somewhere on a path (like $CPPPATH, $FORTRANPATH, etc.).
1323 From Mark Bertoglio:

1326 including generating individual project GUIDs instead of re-using
1331 - Add /opt/SUNWspro/bin to the default execution PATH on Solaris.
1335 - Only expect the Microsoft IDL compiler to emit *_p.c and *_data.c
1336 files if the /proxy and /dlldata switches are used (respectively).
1340 - Have --debug=explain report if a target is being rebuilt because
1341 AlwaysBuild() is specified (instead of "unknown reasons").
1343 - Support {Get,Set}Option('help') to make it easier for SConscript
1344 files to tell if a help option (-h, --help, etc.) has been specified.
1346 - Support {Get,Set}Option('random') so random-dependency interaction
1347 with CacheDir() is controllable from SConscript files.
1349 - Add a new AddOption() function to support user-defined command-
1350 line flags (like --prefix=, --force, etc.).
1352 - Push and retrieve built symlinks to/from a CacheDir() as actual
1353 symlinks, not by copying the file contents.
1355 - Fix how the Action module handles stringifying the shared library
1356 generator in the Tool/mingw.py module.
1358 - When generating a config.h file, print "#define HAVE_{FEATURE} 1"
1359 instad of just "#define HAVE_{FEATURE}", for more compatibility
1360 with Autoconf-style projects.
1362 - Fix expansion of $TARGET, $TARGETS, $SOURCE and $SOURCES keywords in
1363 Visual C/C++ PDB file names.
1365 - Fix locating Visual C/C++ PDB files in build directories.
1367 - Support an env.AddMethod() method and an AddMethod() global function
1368 for adding a new method, respectively, to a construction environment
1369 or an arbitrary object (such as a class).
1371 - Fix the --debug=time option when the -j option is specified and all
1372 files are up to date.
1374 - Add a $SWIGOUTDIR variable to allow setting the swig -outdir option,
1375 and use it to identify files created by the swig -java option.
1377 - Add a $SWIGPATH variable that specifies the path to be searched
1378 for included SWIG files, Also add related $SWIGINCPREFIX and
1379 $SWIGINCSUFFIX variables that specify the prefix and suffix to
1380 be be added to each $SWIGPATH directory when expanded on the SWIG
1383 - More efficient copying of construction environments (mostly borrowed
1384 from copy.deepcopy() in the standard Python library).
1386 - When printing --tree=prune output, don't print [brackets] around
1387 source files, only do so for built targets with children.
1389 - Fix interpretation of Builder source arguments when the Builder has
1390 a src_suffix *and* a source_builder and the argument has no suffix.
1392 - Fix use of expansions like ${TARGET.dir} or ${SOURCE.dir} in the
1393 following construction variables: $FORTRANMODDIR, $JARCHDIR,
1394 $JARFLAGS, $LEXFLAGS, $SWIGFLAGS, $SWIGOUTDIR and $YACCFLAGS.
1396 - Fix dependencies on Java files generated by SWIG so they can be
1397 detected and built in one pass.
1399 - Fix SWIG when used with a BuildDir().
1401 From Leanid Nazdrynau:
1403 - When applying Tool modules after a construction environment has
1404 already been created, don't overwrite existing $CFILESUFFIX and
1405 $CXXFILESUFFIX value.
1407 - Support passing the Java() builder a list of explicit .java files
1408 (not only a list of directories to be scanned for .java files).
1410 - Support passing .java files to the Jar() and JavaH() builders, which
1411 then use the builder underlying the Java() builder to turn them into
1412 .class files. (That is, the Jar()-Java() chain of builders become
1413 multi-step, like the Program()-Object()-CFile() builders.)
1415 - Support passing SWIG .i files to the Java builders (Java(),
1416 Jar(), JavaH()), to cause intermediate .java files to be created
1419 - Add $JAVACLASSPATH and $JAVASOURCEPATH variables, that get added to
1420 the javac "-classpath" and "-sourcepath" options. (Note that SCons
1421 does *not* currently search these paths for implicit dependencies.)
1423 - Commonize initialization of Java-related builders.
1427 - Find Java anonymous classes when the next token after the name is
1428 an open parenthesis.

1441 - Allow worker threads to terminate gracefully when all jobs are
1446 - Add LaTeX scanner support for finding dependencies specified with
1447 the \usepackage{} directive.
1451 RELEASE 0.97 - Thu, 17 May 2007 08:59:41 -0500
1455 - Fix a bug that would make parallel builds stop in their tracks if
1456 Nodes that depended on lists that contained some Nodes built together
1457 caused the reference count to drop below 0 if the Nodes were visited
1458 and commands finished in the wrong order.
1460 - Make sure the DirEntryScanner doesn't choke if it's handed something
1461 that's not a directory (Node.FS.Dir) Node.
1465 RELEASE 0.96.96 - Thu, 12 Apr 2007 12:36:25 -0500

1488 - Fix detecting an erroneous Java anonymous class when the first
1489 non-skipped token after a "new" keyword is a closing brace.
1491 - Fix a regression when a CPPDEFINES list contains a tuple, the second
1492 item of which (the option value) is a construction variable expansion
1493 (e.g. $VALUE) and the value of the variable isn't a string.
1495 - Improve the error message if an IOError (like trying to read a
1496 directory as a file) occurs while deciding if a node is up-to-date.
1498 - Fix "maximum recursion" / "unhashable type" errors in $CPPPATH
1499 PathList expansion if a subsidiary expansion yields a stringable,
1502 - Generate API documentation from the docstrings (using epydoc).
1504 - Fix use of --debug=presub with Actions for out-of-the-box Builders.
1506 - Fix handling nested lists within $CPPPATH, $LIBPATH, etc.
1508 - Fix a "builders_used" AttributeError that real-world Qt initialization
1509 triggered in the refactored suffix handling for Builders.
1511 - Make the reported --debug=time timings meaningful when used with -j.
1512 Better documentation of what the times mean.
1514 - User Guide updates: --random, AlwaysBuild(), --tree=,
1515 --debug=findlibs, --debug=presub, --debug=stacktrace,
1518 - Document (in both man page and User's Guide) that --implicit-cache
1519 ignores changes in $CPPPATH, $LIBPATH, etc.
1521 From Jean-Baptiste Lab:
1523 - Remove hard-coded dependency on Python 2.2 from Debian packaging files.
1527 - Handle spaces in the build target name in Visual Studio project files.
1531 - Re-run LaTeX after BibTeX has been re-run in response to a changed
1534 From Joel B. Mohler:
1536 - Make additional TeX auxiliary files (.toc, .idx and .bbl files)
1537 Precious so their removal doesn't affect whether the necessary
1538 sections are included in output PDF or PostScript files.
1540 From Gary Oberbrunner:
1542 - Fix the ability to import modules in the site_scons directory from
1547 - Make sure parallel (-j) builds all targets even if they show up
1548 multiple times in the child list (as a source and a dependency).
1550 From Matthias Troffaes:
1552 - Don't re-run TeX if the triggering strings (\makeindex, \bibliography
1553 \tableofcontents) are commented out.

1568 - Add the scons.org URL and a package description to the setup.py
1571 - Have the Windows installer add a registry entry for scons.bat in the
1572 "App Paths" key, so scons.bat can be executed without adding the
1573 directory to the %PATH%. (Python itself works this way.)
1577 - Fix looking for default paths in Visual Studio 8.0 (and later).
1579 - Add -lm to the list of default D libraries for linking.
1583 - Provide a more complete write-your-own-Scanner example in the man page.

1588 for more efficient standard input processing.
1592 - Fix the Node.FS.Base.rel_path() method when the two nodes are on

1610 - Fix ParseConfig()'s handling of multiple options in a string that's
1611 replaced a *FLAGS construction variable.
1613 - Have the C++ tools initialize common C compilation variables ($CCFLAGS,
1614 $SHCCFLAGS and $_CCCOMCOM) even if the 'cc' Tool isn't loaded.
1616 From Leanid Nazdrynau:
1618 - Fix detection of Java anonymous classes if a newline precedes the
1621 From Gary Oberbrunner:
1623 - Document use of ${} to execute arbitrary Python code.
1626 1) automatically adding a site_scons subdirectory (in the top-level
1627 SConstruct directory) to sys.path (PYTHONPATH);
1628 2) automatically importing site_scons/site_init.py;
1629 3) automatically adding site_scons/site_tools to the toolpath.

1638 - Fix adding explicitly-named Java inner class files (and any
1639 other file names that may contain a '$') to Jar files.
1643 - Add a NoCache() function to mark targets as unsuitable for propagating
1644 to (or retrieving from) a CacheDir().
1648 - If the swig -noproxy option is used, it won't generate a .py file,
1649 so don't emit it as a target that we expect to be built.
1653 RELEASE 0.96.94 - Sun, 07 Jan 2007 18:36:20 -0600
1655 NOTE: This is a pre-release of 0.97 for testing purposes.
1659 - Allow arbitrary white space after a SWIG %module declaration.
1663 - When compiling resources under MinGW, make sure there's a space
1664 between the --include-dir option and its argument.
1668 - Alleviate long command line issues on Windows by executing command
1669 lines directly via os.spawnv() if the command line doesn't need
1670 shell interpretation (has no pipes, redirection, etc.).
1672 From Walter Franzini:
1674 - Exclude additional Debian packaging files from the copyright check.
1678 - Handle the conflict between the impending Python 2.6 'as' keyword
1679 and our Tool/as.py module name.
1683 - Speed up the Node.FS.Dir.rel_path() method used to generate path names
1684 that get put into the .sconsign* file(s).
1686 - Optimize Node.FS.Base.get_suffix() by computing the suffix once, up
1687 front, when we set the Node's name. (Duh...)
1689 - Reduce the Memoizer's responsibilities to simply counting hits and
1690 misses when the --debug=memoizer option is used, not to actually
1691 handling the key calculation and memoization itself. This speeds
1692 up some configurations significantly, and should cause no functional
1695 - Add a new scons-time script with subcommands for generating
1696 consistent timing output from SCons configurations, extracting
1697 various information from those timings, and displaying them in
1700 - Reduce some unnecessary stat() calls from on-disk entry type checks.
1702 - Fix SideEffect() when used with -j, which was badly broken in 0.96.93.
1704 - Propagate TypeError exceptions when evaluating construction variable
1705 expansions up the stack, so users can see what's going on.
1707 - When disambiguating a Node.FS.Entry into a Dir or File, don't look
1708 in the on-disk source directory until we've confirmed there's no
1709 on-disk entry locally and there *is* one in the srcdir. This avoids
1710 creating a phantom Node that can interfere with dependencies on
1713 - Add an AllowSubstExceptions() function that gives the SConscript
1714 files control over what exceptions cause a string to expand to ''
1715 vs. terminating processing with an error.
1717 - Allow the f90.py and f95.py Tool modules to compile earlier source
1718 source files of earlier Fortran version.
1720 - Fix storing signatures of files retrieved from CacheDir() so they're
1721 correctly identified as up-to-date next invocation.
1723 - Make sure lists of computed source suffixes cached by Builder objects
1724 don't persist across changes to the list of source Builders (so the
1725 addition of suffixes like .ui by the qt.py Tool module take effect).
1727 - Enhance the bootstrap.py script to allow it to be used to execute
1728 SCons more easily from a checked-out source tree.
1732 - Fix post-Memoizer value caching misspellings in Node.FS._doLookup().
1734 From Rob Managan, Dmitry Mikhin and Joel B. Mohler:
1736 - Handle TeX/LaTeX files in subdirectories by changing directory
1737 before invoking TeX/LaTeX.
1739 - Scan LaTeX files for \bibliography lines.
1741 - Support multiple file names in a "\bibliography{file1,file2}" string.
1743 - Handle TeX warnings about undefined citations.
1745 - Support re-running LaTeX if necessary due to a Table of Contents.
1749 - Return LaTeX if "Rerun to get citations correct" shows up on the next
1750 line after the "Warning:" string.
1752 From Gary Oberbrunner:
1754 - Add #include lines to fix portability issues in two tests.
1756 - Eliminate some unnecessary os.path.normpath() calls.
1758 - Add a $CFLAGS variable for C-specific options, leaving $CCFLAGS
1759 for options common to C and C++.
1763 - Have the error message print the missing file that Qt can't find.
1767 - Fix env.MergeFlags() appending to construction variable value of None.
1771 - Fix the "sconsign" script when the .sconsign.dblite file is explicitly
1772 specified on the command line (and not intuited from the old way of
1773 calling it with just ".sconsign").
1775 From Jose Pablo Ezequiel "Pupeno" Fernandez Silva:
1777 - Give the 'lex' tool knowledge of the additional target files produced
1778 by the flex "--header-file=" and "--tables-file=" options.
1780 - Give the 'yacc' tool knowledge of the additional target files produced
1781 by the bison "-g", "--defines=" and "--graph=" options.
1783 - Generate intermediate files with Objective C file suffixes (.m) when
1784 the lex and yacc source files have appropriate suffixes (.lm and .ym).
1788 - Have the mslink.py Tool only look for a 'link' executable on Windows
1791 From Vaclav Smilauer:
1793 - Add support for a "srcdir" keyword argument when calling a Builder,
1794 which will add a srcdir prefix to all non-relative string sources.
1796 From Jonathan Ultis:
1798 - Allow Options converters to take the construction environment as
1799 an optional argument.
1803 RELEASE 0.96.93 - Mon, 06 Nov 2006 00:44:11 -0600
1805 NOTE: This is a pre-release of 0.97 for testing purposes.
1809 - Allow Python Value Nodes to be Builder targets.
1813 - Only filter Visual Studio common filename prefixes on complete
1818 - Fix the build of the SCons documentation on systems that don't
1819 have "python" in the $PATH.
1823 - Enhance ParseConfig() to recognize options that begin with '+'.
1825 From John Calcote, Elliot Murphy:
1827 - Document ways to override the CCPDBFLAGS variable to use the
1828 Microsoft linker's /Zi option instead of the default /Z7.
1830 From Christopher Drexler:
1832 - Make SCons aware bibtex must be called if any \include files
1833 cause creation of a bibliography.
1835 - Make SCons aware that "\bilbiography" in TeX source files means
1836 that related .bbl and .blg bibliography files will be created.
1837 (NOTE: This still needs to search for the string in \include files.)
1841 - Fix inconsistent handling of Action strfunction arguments.
1843 - Preserve white space in display Action strfunction strings.
1845 From James Y. Knight and Gerard Patel:
1847 - Support creation of shared object files from assembly language.
1851 - Speed up the Taskmaster significantly by avoiding unnecessary
1852 re-scans of Nodes to find out if there's work to be done, having it
1853 track the currently-executed top-level target directly and not
1854 through its presence on the target list, and eliminating some other
1855 minor list(s), method(s) and manipulation.
1857 - Fix the expansion of $TARGET and $SOURCE in the expansion of
1858 $INSTALLSTR displayed for non-environment calls to InstallAs().
1860 - Fix the ability to have an Alias() call refer to a directory
1861 name that's not identified as a directory until later.
1863 - Enhance runtest.py with an option to use QMTest as the harness.
1864 This will become the default behavior as we add more functionality
1867 - Let linking on mingw use the default function that chooses $CC (gcc)
1868 or $CXX (g++) depending on whether there are any C++ source files.
1870 - Work around a bug in early versions of the Python 2.4 profile module
1871 that caused the --profile= option to fail.
1873 - Only call Options validators and converters once when initializing a
1874 construction environment.
1876 - Fix the ability of env.Append() and env.Prepend(), in all known Python
1877 versions, to handle different input value types when the construction
1878 variable being updated is a dictionary.
1880 - Add a --cache-debug option for information about what files it's
1881 looking for in a CacheDir().
1883 - Document the difference in construction variable expansion between
1884 {Action,Builder}() and env.{Action,Builder}().
1886 - Change the name of env.Copy() to env.Clone(), keeping the old name
1887 around for backwards compatibility (with the intention of eventually
1888 phasing it out to avoid confusion with the Copy() Action factory).
1892 - Support cleaning and scanning SWIG-generated files.
1896 - Allow selection of Visual Studio version by setting $MSVS_VERSION
1897 after construction environment initialization.
1899 From Jean-Baptiste Lab:
1901 - Try using zipimport if we can't import Tool or Platform modules
1902 using the normal "imp" module. This allows SCons to be packaged
1903 using py2exe's all-in-one-zip-file approach.
1907 - Do not re-scan files if the scanner returns no implicit dependencies.
1909 From Sanjoy Mahajan:
1911 - Change use of $SOURCES to $SOURCE in all TeX-related Tool modules.
1913 From Joel B. Mohler:
1915 - Make SCons aware that "\makeindex" in TeX source files means that
1916 related .ilg, .ind and .idx index files will be created.
1917 (NOTE: This still needs to search for the string in \include files.)
1919 - Prevent scanning the TeX .aux file for additional files from
1920 trying to remove it twice when the -c option is used.
1922 From Leanid Nazdrynau:
1924 - Give the MSVC RES (resource) Builder a src_builder list and a .rc
1925 src_suffix so other builders can generate .rc files.
1927 From Matthew A. Nicholson:
1929 - Enhance Install() and InstallAs() to handle directory trees as sources.
1933 - Don't use the -fPIC flag when using gcc on Windows (e.g. MinGW).
1937 - Add an env.ParseFlags() method that provides separate logic for
1938 parsing GNU tool chain flags into a dictionary.
1940 - Add an env.MergeFlags() method to apply an arbitrary dictionary
1941 of flags to a construction environment's variables.
1943 From Gary Oberbrunner:
1945 - Fix parsing tripartite Intel C compiler version numbers on Linux.
1947 - Extend the ParseConfig() function to recognize -arch and
1950 - Have the error message list the known suffixes when a Builder call
1951 can't build a source file with an unknown suffix.
1953 From Karol Pietrzak:
1955 - Avoid recursive calls to main() in the program snippet used by the
1956 SConf subsystem to test linking against libraries. This changes the
1957 default behavior of CheckLib() and CheckLibWithHeader() to print
1958 "Checking for C library foo..." instead of "Checking for main()
1959 in C library foo...".
1963 - Throw an exception if a command called by ParseConfig() or
1964 ParseFlags() returns an error.
1966 From Stefan Seefeld:
1968 - Initial infrastructure for running SCons tests under QMTest.
1972 - Fix tests that fail due to gcc warnings.
1974 From Dobes Vandermeer:
1976 - In stack traces, print the full paths of SConscript files.
1980 - Fix detection of Visual C++ Express Edition.
1982 From Dobes Vandermeer:
1984 - Let the src_dir option to the SConscript() function affect all the
1985 the source file paths, instead of treating all source files paths
1986 as relative to the SConscript directory itself.
1988 From Nicolas Vigier:
1990 - Fix finding Fortran modules in build directories.
1992 - Fix use of BuildDir() when the source file in the source directory
1993 is a symlink with a relative path.
1997 - Fix the Memoizer when the SCons Python modules are executed from
1998 .pyo files at different locations from where they were compiled.
2002 - Fix missing os.path.join() when constructing the $FRAMEWORKSDKDIR/bin.
2006 RELEASE 0.96.92 - Mon, 10 Apr 2006 21:08:22 -0400
2008 NOTE: This was a pre-release of 0.97 for testing purposes.
2012 - Fix the intelc.py Tool module to not throw an exception if the
2013 only installed version is something other than ia32.
2015 - Set $CCVERSION when using gcc.
2019 - Support generating project and solution files for Microsoft
2020 Visual Studio version 8.
2022 - Support generating more than one project file for a Microsoft
2023 Visual Studio solution file.
2025 - Add support for a support "runfile" parameter to Microsoft
2026 Visual Studio project file creation.
2028 - Put the project GUID, not the solution GUID, in the right spot
2029 in the solution file.
2031 From Erling Andersen:
2033 - Fix interpretation of Node.FS objects wrapped in Proxy instances,
2034 allowing expansion of things like ${File(TARGET)} in command lines.
2036 From Stanislav Baranov:
2038 - Add a separate MSVSSolution() Builder, with support for the
2039 following new construction variables: $MSVSBUILDCOM, $MSVSCLEANCOM,
2040 $MSVSENCODING, $MSVSREBUILDCOM, $MSVSSCONS, $MSVSSCONSCOM,
2041 $MSVSSCONSFLAGS, $MSVSSCONSCRIPT and $MSVSSOLUTIONCOM.
2043 From Ralph W. Grosse-Kunstleve and Patrick Mezard:
2045 - Remove unneceesary (and incorrect) SCons.Util strings on some function
2046 calls in SCons.Util.
2050 - Fix C/C++ compiler selection on AIX to not always use the external $CC
2051 environment variable.
2053 From August Hörandl:
2055 - Add a scanner for \include and \import files, with support for
2056 searching a directory list in $TEXINPUTS (imported from the external
2059 - Support $MAKEINDEX, $MAKEINDEXCOM, $MAKEINDEXCOMSTR and
2060 $MAKEINDEXFLAGS for generating indices from .idx files.
2062 From Steven Johnson:
2064 - Add a NoClean() Environment method and function to override removal
2065 of targets during a -c clean, including documentation and tests.
2069 - Check for whether files exist on disk by listing the directory
2070 contents, not calling os.path.exists() file by file. This is
2071 somewhat more efficient in general, and may be significantly
2072 more efficient on Windows.
2074 - Minor speedups in the internal is_Dict(), is_List() and is_String()
2077 - Fix a signature refactoring bug that caused Qt header files to
2078 get re-generated every time.
2080 - Don't fail when writing signatures if the .sconsign.dblite file is
2081 owned by a different user (e.g. root) from a previous run.
2083 - When deleting variables from stacked OverrideEnvironments, don't
2084 throw a KeyError if we were able to delte the variable from any
2085 Environment in the stack.
2087 - Get rid of the last indentation tabs in the SCons source files and
2088 add -tt to the Python invocations in the packaging build and the
2089 tests so they don't creep back in.
2091 - In Visual Studio project files, put quotes around the -C directory
2092 so everything works even if the path has spaces in it.
2094 - The Intel Fortran compiler uses -object:$TARGET, not "-o $TARGET",
2095 when building object files on Windows. Have the the ifort Tool
2096 modify the default command lines appropriately.
2098 - Document the --debug=explain option in the man page. (How did we
2101 - Add a $LATEXRETRIES variable to allow configuration of the number of
2102 times LaTex can be re-called to try to resolve undefined references.
2104 - Change the order of the arguments to Configure.Checklib() to match
2107 - Handle signature calculation properly when the Python function used
2108 for a FunctionAction is an object method.
2110 - On Windows, assume that absolute path names without a drive letter
2111 refer to the drive on which the SConstruct file lives.
2113 - Add /usr/ccs/bin to the end of the the default external execution
2116 - Add $PKGCHK and $PKGINFO variables for use on Solaris when searching
2117 for the SunPRO C++ compiler. Make the default value for $PKGCHK
2118 be /usr/sbin/pgkchk (since /usr/sbin isn't usually on the external
2121 - Fix a man page example of overriding variables when calling
2122 SharedLibrary() to also set the $LIBSUFFIXES variable.
2124 - Add a --taskmastertrace=FILE option to give some insight on how
2125 the taskmaster decides what Node to build next.
2127 - Changed the names of the old $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
2128 $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX construction variables to
2129 new $WINDOWSDEFPREFIX, $WINDOWSDEFSUFFIX, $WINDOWSDLLPREFIX and
2130 $WINDOWSIMPLIBPREFIX construction variables. The old names are now
2131 deprecated, but preserved for backwards compatibility.
2133 - Fix (?) a runtest.py hang on Windows when the --xml option is used.
2135 - Change the message when an error occurs trying to interact with the
2136 file system to report the target(s) in square brackets (as before) and
2137 the actual file or directory that encountered the error afterwards.
2141 - Add x64 support for Microsoft Visual Studio 8.
2143 From Baptiste Lepilleur:
2145 - Support the --debug=memory option on Windows when the Python version
2146 has the win32process and win32api modules.
2148 - Add support for Visual Studio 2005 Pro.
2150 - Fix portability issues in various tests: test/Case.py,
2151 Test/Java/{JAR,JARCHDIR,JARFLAGS,JAVAC,JAVACFLAGS,JAVAH,RMIC}.py,
2152 test/MSVS/vs-{6.0,7.0,7.1,8.0}-exec.py,
2153 test/Repository/{Java,JavaH,RMIC}.py,
2154 test/QT/{generated-ui,installed,up-to-date,warnings}.py,
2157 - Ignore pkgchk errors on Solaris when searching for the C++ compiler.
2159 - Speed up the SCons/EnvironmentTests.py unit tests.
2161 - Add a --verbose= option to runtest.py to print executed commands
2162 and their output at various levels.
2164 From Christian Maaser:
2166 - Add support for Visual Studio Express Editions.
2168 - Add support for Visual Studio 8 *.manifest files, includng
2169 new $WINDOWS_INSERT_MANIFEST, $WINDOWSPROGMANIFESTSUFFIX,
2170 $WINDOWSPROGMANIFESTPREFIX, $WINDOWSPROGMANIFESTSUFFIX,
2171 $WINDOWSSHLIBMANIFESTPREFIX and $WINDOWSSHLIBMANIFESTSUFFIX
2172 construction variables.
2176 - Fix detection of additional Java inner classes following use of a
2177 "new" keyword inside an inner class.
2179 From Sanjoy Mahajan:
2181 - Correct TeX-related command lines to just $SOURCE, not $SOURCES
2183 From Patrick Mezard:
2185 - Execute build commands for a command-line target if any of the
2186 files built along with the target is out of date or non-existent,
2187 not just if the command-line target itself is out of date.
2189 - Fix the -n option when used with -c to print all of the targets
2190 that will be removed for a multi-target Builder call.
2192 - If there's no file in the source directory, make sure there isn't
2193 one in the build directory, too, to avoid dangling files left
2194 over from previous runs when a source file is removed.
2196 - Allow AppendUnique() and PrependUnique() to append strings (and
2197 other atomic objects) to lists.
2199 From Joel B. Mohler:
2201 - Extend latex.py, pdflatex.py, pdftex.py and tex.py so that building
2202 from both TeX and LaTeX files uses the same logic to call $BIBTEX
2203 when it's necessary, to call $MAKEINDEX when it's necessary, and to
2204 call $TEX or $LATEX multiple times to handle undefined references.
2206 - Add an emitter to the various TeX builders so that the generated
2207 .aux and .log files also get deleted by the -c option.
2209 From Leanid Nazdrynau:
2211 - Fix the Qt UIC scanner to work with generated .ui files (by using
2212 the FindFile() function instead of checking by-hand for the file).
2214 From Jan Nieuwenhuizen:
2216 - Fix a problem with interpreting quoted argument lists on command lines.
2220 - Add /sw/bin to the default execution PATH on Mac OS X.
2224 - When building a .jar file and there is a $JARCHDIR, put the -C
2225 in front of each .class file on the command line.
2227 - Recognize the Java 1.5 enum keyword.
2229 From Asfand Yar Qazi:
2231 - Add /opt/bin to the default execution PATH on all POSIX platforms
2232 (between /usr/local/bin and /bin).
2236 - Fix the use of Configure() contexts from nested subsidiary
2239 From Christoph Schulz:
2241 - Add support for $CONFIGUREDIR and $CONFIGURELOG variables to control
2242 the directory and logs for configuration tests.
2244 - Add support for a $INSTALLSTR variable.
2246 - Add support for $RANLIBCOM and $RANLIBCOMSTR variables (which fixes
2247 a bug when setting $ARCOMSTR).
2251 - Add use of $CPPDEFINES to $RCCOM (resource file compilation) on MinGW.
2253 From Erick Tryzelaar:
2255 - Fix the error message when trying to report that a given option is
2256 not gettable/settable from an SConscript file.
2258 From Dobes Vandermeer:
2260 - Add support for SCC and other settings in Microsoft Visual
2261 Studio project and solution files: $MSVS_PROJECT_BASE_PATH,
2262 $MSVS_PROJECT_GUID, $MSVS_SCC_AUX_PATH, $MSVS_SCC_LOCAL_PATH,
2263 $MSVS_SCC_PROJECT_NAME, $MSVS_SCC_PROVIDER,
2265 - Add support for using a $SCONS_HOME variable (imported from the
2266 external environment, or settable internally) to put a shortened
2267 SCons execution line in the Visual Studio project file.
2269 From David J. Van Maren:
2271 - Only filter common prefixes from source files names in Visual Studio
2272 project files if the prefix is a complete (sub)directory name.
2276 - If $MSVSVERSIONS is already set, don't overwrite it with
2277 information from the registry.
2281 RELEASE 0.96.91 - Thu, 08 Sep 2005 07:18:23 -0400
2283 NOTE: This was a pre-release of 0.97 for testing purposes.
2287 - Have the environment store the toolpath and re-use it to find Tools
2288 modules during later Copy() or Tool() calls (unless overridden).
2290 - Normalize the directory path names in SConsignFile() database
2291 files so the same signature file can interoperate on Windows and
2292 non-Windows systems.
2294 - Make --debug=stacktrace print a stacktrace when a UserError is thrown.
2296 - Remove an old, erroneous cut-and-paste comment in Scanner/Dir.py.
2298 From Stanislav Baranov:
2300 - Make it possible to support with custom Alias (sub-)classes.
2302 - Allow Builders to take empty source lists when called.
2304 - Allow access to both TARGET and SOURCE in $*PATH expansions.
2306 - Allow SConscript files to modify BUILD_TARGETS.
2308 From Timothee Besset:
2310 - Add support for Objective C/C++ .m and .mm file suffixes (for
2315 - Fix the PharLap linkloc.py module to use target+source arguments
2316 when calling env.subst().
2318 From Bjorn Eriksson:
2320 - Fix an incorrect Command() keyword argument in the man page.
2322 - Add a $TEMPFILEPREFIX variable to control the prefix or flag used
2323 to pass a long-command-line-execution tempfile to a command.
2327 - Enhanced the SCons setup.py script to install man pages on
2330 - Add support for an Options.FormatOptionHelpText() method that can
2331 be overridden to customize the format of Options help text.
2333 - Add a global name for the Entry class (which had already been
2336 - Fix re-scanning of generated source files for implicit dependencies
2337 when the -j option is used.
2339 - Fix a dependency problem that caused $LIBS scans to not be added
2340 to all of the targets in a multiple-target builder call, which
2341 could cause out-of-order builds when the -j option is used.
2343 - Store the paths of source files and dependencies in the .sconsign*
2344 file(s) relative to the target's directory, not relative to the
2345 top-level SConstruct directory. This starts to make it possible to
2346 subdivide the dependency tree arbitrarily by putting an SConstruct
2347 file in every directory and using content signatures.
2349 - Add support for $YACCHFILESUFFIX and $YACCHXXFILESUFFIX variables
2350 that accomodate parser generators that write header files to a
2351 different suffix than the hard-coded .hpp when the -d option is used.
2353 - The default behavior is now to store signature information in a
2354 single .sconsign.dblite file in the top-level SConstruct directory.
2355 The old behavior of a separate .sconsign file in each directory can
2356 be specified by calling SConsignFile(None).
2358 - Remove line number byte codes within the signature calculation
2359 of Python function actions, so that changing the location of an
2360 otherwise unmodified Python function doesn't cause rebuilds.
2362 - Fix AddPreAction() and AddPostAction() when an action has more than
2363 one target file: attach the actions to the Executor, not the Node.
2365 - Allow the source directory of a BuildDir / build_dir to be outside
2366 of the top-level SConstruct directory tree.
2368 - Add a --debug=nomemoizer option that disables the Memoizer for clearer
2369 looks at the counts and profiles of the underlying function calls,
2370 not the Memoizer wrappers.
2372 - Print various --debug= stats even if we exit early (e.g. using -h).
2374 - Really only use the cached content signature value if the file
2375 is older than --max-drift, not just if --max-drift is set.
2377 - Remove support for conversion from old (pre 0.96) .sconsign formats.
2379 - Add support for a --diskcheck option to enable or disable various
2380 on-disk checks: that File and Dir nodes match on-disk entries;
2381 whether an RCS file exists for a missing source file; whether an
2382 SCCS file exists for a missing source file.
2384 - Add a --raw argument to the sconsign script, so it can print a
2385 raw representation of each entry's NodeInfo dictionary.
2387 - Add the 'f90' and 'f95' tools to the list of Fortran compilers
2388 searched for by default.
2390 - Add the +Z option by default when compiling shared objects on
2395 - Handle Visual Studio project and solution files in Unicode.
2397 From Sanjoy Mahajan:
2399 - Fix a bad use of Copy() in an example in the man page, and a
2400 bad regular expression example in the man page and User's Guide.
2404 - Have the Visual Studio project file(s) echo "Starting SCons" before
2405 executing SCons, mainly to work around a quote-stripping bug in
2406 (some versions of?) the Windows cmd command executor.
2408 From Georg Mischler:
2410 - Remove the space after the -o option when invoking the Borland
2411 BCC compiler; some versions apparently require that the file name
2412 argument be concatenated with the option.
2414 From Leanid Nazdrynau:
2416 - Fix the Java parser's handling of backslashes in strings.
2420 - Add construction variables to support frameworks on Mac OS X:
2421 $FRAMEWORKS, $FRAMEWORKPREFIX, $FRAMEWORKPATH, $FRAMEWORKPATHPREFIX.
2423 - Re-order link lines so the -o option always comes right after the
2426 From Gary Oberbrunner:
2428 - Add support for Intel C++ beta 9.0 (both 32 and 64 bit versions).
2430 - Document the new $FRAMEWORK* variables for Mac OS X.
2432 From Karol Pietrzak:
2434 - Add $RPATH (-R) support to the Sun linker Tool (sunlink).
2436 - Add a description of env.subst() to the man page.
2440 - Look in the right directory, not always the local directory, for a
2441 same-named file or directory conflict on disk.
2443 - On Windows, preserve the external environment's %SYSTEMDRIVE%
2448 - Have the Fortran module emitter look for Fortan modules to be created
2449 relative to $FORTRANMODDIR, not the top-level directory.
2451 - When saving Options to a file, run default values through the
2452 converter before comparing them with the set values. This correctly
2453 suppresses Boolean Option values from getting written to the saved
2454 file when they're one of the many synonyms for a default True or
2457 - Fix the Fortran Scanner's ability to handle a module being used
2458 in the same file in which it is defined.
2462 - Add the -KPIC option by default when compiling shared objects on
2465 - Change the default suffix for Solaris objects to .o, to conform to
2466 Sun WorkShop's expectations. Change the profix to so_ so they can
2467 still be differentiated from static objects in the same directory.
2471 - When calling the resource compiler on MinGW, add --include-dir and
2472 the source directory so it finds the source file.
2474 - Update EnsureSConsVersion() to support revision numbers.
2478 - Fix a misplaced line in the man page.
2482 RELEASE 0.96.90 - Tue, 15 Feb 2005 21:21:12 +0000
2484 NOTE: This was a pre-release of 0.97 for testing purposes.
2488 - Fix Java parsing to avoid erroneously identifying a new array
2489 of class instances as an anonymous inner class.
2491 - Fix a typo in the man page description of PathIsDirCreate.
2495 - Allow Help() to be called multiple times, appending to the help
2498 - Allow Tools found on a toolpath to import Python modules from
2499 their local directory.
2501 From Steve Christensen:
2503 - Handle exceptions from Python functions as build actions.
2505 - Add a set of canned PathOption validators: PathExists (the default),
2506 PathIsFile, PathIsDir and PathIsDirCreate.
2510 - Add support for .lex and .yacc file suffixes for Lex and Yacc files.
2514 - Huge performance improvement: wrap the tuples representing an
2515 include path in an object, so that the time it takes to hash the
2516 path doesn't grow porportionally to the length of the path.
2518 From Gottfried Ganssauge:
2520 - Fix SCons on SuSE/AMD-64 Linux by having the wrapper script also
2521 check for the build engine in the parent directory of the Python
2522 library directory (/usr/lib64 instead of /usr/lib).
2524 From Stephen Kennedy:
2526 - Speed up writing the .sconsign file at the end of a run by only
2527 calling sync() once at the end, not after every entry.
2531 - When compiling with Microsoft Visual Studio, don't include the ATL and
2532 MFC directories in the default INCLUDE and LIB environment variables.
2534 - Remove the following deprecated features: the ParseConfig()
2535 global function (deprecated in 0.93); the misspelled "validater"
2536 keyword to the Options.Add() method (deprecated in 0.91); the
2537 SetBuildSignatureType(), SetContentSignatureType(), SetJobs() and
2538 GetJobs() global functions (deprecated in 0.14).
2540 - Fix problems with corrupting the .sconsign.dblite file when
2541 interrupting builds by writing to a temporary file and renaming,
2542 not writing the file directly.
2544 - Fix a 0.96 regression where when running with -k, targets built from
2545 walking dependencies later on the command line would not realize
2546 that a dependency had failed an earlier build attempt, and would
2547 try to rebuild the dependent targets.
2549 - Change the final messages when using -k and errors occur from
2550 "{building,cleaning} terminated because of errors" to "done
2551 {building,cleaning} targets (errors occurred during {build,clean})."
2553 - Allow Configure.CheckFunc() to take an optional header argument
2554 (already supported by Conftest.py) to specify text at the top of
2555 the compiled test file.
2557 - Fix the --debug=explain output when a Python function action changed
2558 so it prints a meaningful string, not the binary representation of
2559 the function contents.
2561 - Allow a ListOption's default value(s) to be a Python list of specified
2562 values, not just a string containing a comma-separated list of names.
2564 - Add a ParseDepends() function that will parse up a list of explicit
2565 dependencies from a "make depend" style file.
2567 - Support the ability to change directory when executing an Action
2568 through "chdir" keyword arguments to Action and Builder creation
2571 - Fix handling of Action ojects (and other callables that don't match
2572 our calling arguments) in construction variable expansions.
2574 - On Win32, install scons.bat in the Python directory when installing
2575 from setup.py. (The bdist_wininst installer was already doing this.)
2577 - Fix env.SConscript() when called with a list of SConscipt files.
2578 (The SConscript() global function already worked properly.)
2580 - Add a missing newline to the end of the --debug=explain "unknown
2583 - Enhance ParseConfig() to work properly for spaces in between the -I,
2584 -L and -l options and their arguments.
2586 - Packaging build fix: Rebuild the files that are use to report the
2587 --version of SCons whenever the development version number changes.
2589 - Fix the ability to specify a target_factory of Dir() to a Builder,
2590 which the default create-a-directory Builder was interfering with.
2592 - Mark a directory as built if it's created as part of the preparation
2593 for another target, to avoid trying to build it again when it comes
2594 up in the target list.
2596 - Allow a function with the right calling signature to be put directly
2597 in an Environment's BUILDERS dictionary, making for easier creation
2598 and use of wrappers (pseudo-Builders) that call other Builders.
2600 - On Python 2.x, wrap lists of Nodes returned by Builders in a UserList
2601 object that adds a method that makes str() object return a string
2602 with all of the Nodes expanded to their path names. (Builders under
2603 Python 1.5.2 still return lists to avoid TypeErrors when trying
2604 to extend() list, so Python 1.5.2 doesn't get pretty-printing of Node
2605 lists, but everything should still function.)
2607 - Allow Aliases to have actions that will be executed whenever
2608 any of the expanded Alias targets are out of date.
2610 - Fix expansion of env.Command() overrides within target and
2613 - Support easier customization of what's displayed by various default
2614 actions by adding lots of new construction variables: $ARCOMSTR,
2615 $ASCOMSTR, $ASPPCOMSTR, $BIBTEXCOMSTR, $BITKEEPERCOMSTR, $CCCOMSTR,
2616 $CVSCOMSTR, $CXXCOMSTR, $DCOMSTR, $DVIPDFCOMSTR, $F77COMSTR,
2617 $F90COMSTR, $F95COMSTR, $FORTRANCOMSTR, $GSCOMSTR, $JARCOMSTR,
2618 $JAVACCOMSTR, $JAVAHCOMSTR, $LATEXCOMSTR, $LEXCOMSTR, $LINKCOMSTR,
2619 $M4COMSTR, $MIDLCOMSTR, $P4COMSTR, $PCHCOMSTR, $PDFLATEXCOMSTR,
2620 $PDFTEXCOMSTR, $PSCOMSTR, $QT_MOCFROMCXXCOMSTR, $QT_MOCFROMHCOMSTR,
2621 $QT_UICCOMSTR, $RCCOMSTR, $REGSVRCOMSTR, $RCS_COCOMSTR, $RMICCOMSTR,
2622 $SCCSCOMSTR, $SHCCCOMSTR, $SHCXXCOMSTR, $SHF77COMSTR, $SHF90COMSTR,
2623 $SHF95COMSTR, $SHFORTRANCOMSTR, $SHLINKCOMSTR, $SWIGCOMSTR,
2624 $TARCOMSTR, $TEXCOMSTR, $YACCCOMSTR and $ZIPCOMSTR.
2626 - Add an optional "map" keyword argument to ListOption() that takes a
2627 dictionary to map user-specified values to legal values from the list
2628 (like EnumOption() already doee).
2630 - Add specific exceptions to try:-except: blocks without any listed,
2631 so that they won't catch and mask keyboard interrupts.
2633 - Make --debug={tree,dtree,stree} print something even when there's
2636 - Fix how Scanners sort the found dependencies so that it doesn't
2637 matter whether the dependency file is in a Repository or not.
2638 This may cause recompilations upon upgrade to this version.
2640 - Make AlwaysBuild() work with Alias and Python value Nodes (making
2641 it much simpler to support aliases like "clean" that just invoke
2642 an arbitrary action).
2644 - Have env.ParseConfig() use AppendUnique() by default to suppress
2645 duplicate entries from multiple calls. Add a "unique" keyword
2646 argument to allow the old behavior to be specified.
2648 - Allow the library modules imported by an SConscript file to get at
2649 all of the normally-available global functions and variables by saying
2650 "from SCons.Script import *".
2652 - Add a --debug=memoizer option to print Memoizer hit/mass statistics.
2654 - Allow more than one --debug= option to be set at a time.
2656 - Change --debug=count to report object counts before and after
2657 reading SConscript files and before and after building targets.
2659 - Change --debug=memory output to line up the numbers and to better
2660 match (more or less) the headers on the --debug=count columns.
2662 - Speed things up when there are lists of targets and/or sources by
2663 getting rid of some N^2 walks of the lists involved.
2665 - Cache evaluation of LazyActions so we don't create a new object
2666 for each invocation.
2668 - When scanning, don't create Nodes for include files that don't
2669 actually exist on disk.
2671 - Make supported global variables CScanner, DScanner, ProgramScanner and
2672 SourceFileScanner. Make SourceFileScanner.add_scanner() a supported
2673 part of the public interface. Keep the old SCons.Defaults.*Scan names
2674 around for a while longer since some people were already using them.
2676 - By default, don't scan directories for on-disk files. Add a
2677 DirScanner global scanner that can be used in Builders or Command()
2678 calls that want source directory trees scanned for on-disk changes.
2679 Have the Tar() and Zip() Builders use the new DirScanner to preserve
2680 the behavior of rebuilding a .tar or .zip file if any file or
2681 directory under a source tree changes. Add Command() support for
2682 a source_scanner keyword argument to Command() that can be set to
2683 DirScanner to get this behavior.
2685 - Documentation changes: Explain that $CXXFLAGS contains $CCFLAGS
2686 by default. Fix a bad target_factory example in the man page.
2687 Add appendices to the User's Guide to cover the available Tools,
2688 Builders and construction variables. Comment out the build of
2689 the old Python 10 paper, which doesn't build on all systems and
2690 is old enough at this point that it probably isn't worth the
2691 effort to make it do so.
2695 - Avoid "maximum recursion limit" errors when removing $(-$) pairs
2696 from long command lines.
2698 From Clive Levinson:
2700 - Make ParseConfig() recognize and add -mno-cygwin to $LINKFLAGS and
2701 $CCFLAGS, and -mwindows to $LINKFLAGS.
2703 From Michael McCracken:
2705 - Add a new "applelink" tool to handle the things like Frameworks and
2706 bundles that Apple has added to gcc for linking.
2708 - Use more appropriate default search lists of linkers, compilers and
2709 and other tools for the 'darwin' platform.
2711 - Add a LoadableModule Builder that builds a bundle on Mac OS X (Darwin)
2712 and a shared library on other systems.
2714 - Improve SWIG tests for use on Mac OS X (Darwin).
2718 - Enhance the tests to guarantee persistence of ListOption
2719 values in saved options files.
2721 - Supply the help text when -h is used with the -u, -U or -D options.
2723 From Christian Neeb:
2725 - Fix the Java parser's handling of string definitions to avoid ignoring
2728 From Han-Wen Nienhuys:
2730 - Optimize variable expansion by: using the re.sub() method (when
2731 possible); not using "eval" for variables for which we can fetch the
2732 value directory; avoiding slowing substitution logic when there's no
2735 From Gary Oberbrunner:
2737 - Add an Environment.Dump() method to print the contents of a
2738 construction environment.
2740 - Allow $LIBS (and similar variables) to contain explicit File Nodes.
2742 - Change ParseConfig to add the found library names directly to the
2743 $LIBS variable, instead of returning them.
2745 - Add ParseConfig() support for the -framework GNU linker option.
2747 - Add a PRINT_CMD_LINE_FUNC construction variable to allow people
2748 to filter (or log) command-line output.
2750 - Print an internal Python stack trace in response to an otherwise
2751 unexplained error when --debug=stacktrace is specified.
2753 - Add a --debug=findlibs option to print what's happening when
2754 the scanner is searching for libraries.
2756 - Allow Tool specifications to be passed a dictionary of keyword
2759 - Support an Options default value of None, in which case the variable
2760 will not be added to the construction environment unless it's set
2761 explicitly by the user or from an Options file.
2763 - Avoid copying __builtin__ values into a construction environment's
2764 dictionary when evaluating construction variables.
2766 - Add a new cross-platform intelc.py Tool that can detect and
2767 configure the Intel C++ v8 compiler on both Windows, where it's
2768 named icl, and Linux, where it's named icc. It also checks that
2769 the directory specified in the Windows registry exists, and sets a
2770 new $INTEL_C_COMPILER_VERSION construction variable to identify the
2771 version being used. (Niall Douglas contributed an early prototype
2772 of parts of this module.)
2774 - Fix the private Conftest._Have() function so it doesn't change
2775 non-alphanumeric characters to underscores.
2777 - Supply a better error message when a construction variable expansion
2778 has an unknown attribute.
2780 - Documentation changes: Update the man page to describe use of
2781 filenames or Nodes in $LIBS.
2785 - Have the linkloc tool use $MSVS_VERSION to select the Microsoft
2786 Visual Studio version to use.
2790 - Fix the Builder name returned from ListBuilders and other instances
2791 of subclasses of the BuilderBase class.
2793 - Add Builders and construction variables to support rpcgen:
2794 RPCGenClient(), RPCGenHeader(), RPCGenService(), RPCGenXDR(),
2795 $RPCGEN, $RPCGENFLAGS, $RPCGENCLIENTFLAGS, $RPCGENHEADERFLAGS,
2796 $RPCGENSERVICEFLAGS, $RPCGENXDRFLAGS.
2798 - Update the man page to document that prefix and suffix Builder
2799 keyword arguments can be strings, callables or dictionaries.
2801 - Provide more info in the error message when a user tries to build
2802 a target multiple ways.
2804 - Fix Delete() when a file doesn't exist and must_exist=1. (We were
2805 unintentionally dependent on a bug in versions of the Python shutil.py
2806 module prior to Python 2.3, which would generate an exception for
2807 a nonexistent file even when ignore_errors was set.)
2809 - Only replace a Node's builder with a non-null source builder.
2811 - Fix a stack trace when a suffix selection dictionary is passed
2812 an empty source file list.
2814 - Allow optional names to be attached to Builders, for default
2815 Builders that don't get attached to construction environments.
2817 - Fix problems with Parallel Task Exception handling.
2819 - Build targets in an associated BuildDir even if there are targets
2820 or subdirectories locally in the source directory.
2822 - If a FunctionAction has a callable class as its underlying Python
2823 function, use its strfunction() method (if any) to display the
2826 - Fix handling when BuildDir() exists but is unwriteable. Add
2827 "Stop." to those error messages for consistency.
2829 - Catch incidents of bad builder creation (without an action) and
2830 supply meaningful error messages.
2832 - Fix handling of src_suffix values that aren't extensions (don't
2835 - Don't retrieve files from a CacheDir, but report what would happen,
2836 when the -n option is used.
2838 - Use the source_scanner from the target Node, not the source node
2841 - Internal Scanners fixes: Make sure Scanners are only passed Nodes.
2842 Fix how a Scanner.Selector called its base class initialization.
2843 Make comparisons of Scanner objects more robust. Add a name to
2844 an internal default ObjSourceScanner.
2846 - Add a deprecated warning for use of the old "scanner" keyword argument
2847 to Builder creation.
2849 - Improve the --debug=explain message when the build action changes.
2851 - Test enhancements in SourceCode.py, option-n.py, midl.py. Better
2852 Command() and Scanner test coverage. Improved test infrastructure
2855 - Refactor the interface between Action and Executor objects to treat
2858 - The --debug=presub option will now report the pre-substitution
2859 each action seprately, instead of reporting the entire list before
2860 executing the actions one by one.
2862 - The --debug=explain option explaining a changed action will now
2863 (more correctly) show pre-substitution action strings, instead of
2864 the commands with substituted file names.
2866 - A Node (file) will now be rebuilt if its PreAction or PostAction
2869 - Python Function actions now have their calling signature (target,
2870 source, env) reported correctly when displayed.
2872 - Fix BuildDir()/build_dir handling when the build_dir is underneath
2873 the source directory and trying to use entries from the build_dir
2874 as sources for other targets in the build-dir.
2876 - Fix hard-coding of JDK path names in various Java tests.
2878 - Handle Python stack traces consistently (stop at the SConscript stack
2879 frame, by default) even if the Python source code isn't available.
2881 - Improve the performance of the --debug={tree,dtree} options.
2883 - Add --debug=objects logging of creation of OverrideWarner,
2884 EnvironmentCopy and EnvironmentOverride objects.
2886 - Fix command-line expansion of Python Value Nodes.
2888 - Internal cleanups: Remove an unnecessary scan argument. Associate
2889 Scanners only with Builders, not nodes. Apply overrides once when
2890 a Builder is called, not in multiple places. Cache results from the
2891 Node.FS.get_suffix() and Node.get_build_env() methods. Use the Python
2892 md5 modules' hexdigest() method, if there is one. Have Taskmaster
2893 call get_stat() once for each Node and re-use the value instead of
2894 calling it each time it needs the value. Have Node.depends_on()
2895 re-use the list from the children() method instead of calling it
2898 - Use the correct scanner if the same source file is used for targets in
2899 two different environments with the same path but different scanners.
2901 - Collect logic for caching values in memory in a Memoizer class,
2902 which cleans up a lot of special-case code in various methods and
2903 caches additional values to speed up most configurations.
2905 - Add a PathAccept validator to the list of new canned PathOption
2910 - Documentation changes: Use $CPPDEFINES instead of $CCFLAGS in man
2915 - Allow $JARCHDIR to be expanded to other construction variables.
2917 From Christoph Wiedemann:
2919 - Add an Environment.SetDefault() method that only sets values if
2920 they aren't already set.
2922 - Have the qt.py Tool not override variables already set by the user.
2924 - Add separate $QT_BINPATH, $QT_CPPPATH and $QT_LIBPATH variables
2925 so these can be set individually, instead of being hard-wired
2928 - The %TEMP% and %TMP% external environment variables are now propagated
2929 automatically to the command execution environment on Windows systems.
2931 - A new --config= command-line option allows explicit control of
2932 of when the Configure() tests are run: --config=force forces all
2933 checks to be run, --config=cache uses all previously cached values,
2934 --config=auto (the default) runs tests only when dependency analysis
2935 determines it's necessary.
2937 - The Configure() subsystem can now write a config.h file with values
2938 like HAVE_STDIO_H, HAVE_LIBM, etc.
2940 - The Configure() subsystem now executes its checks silently when the
2941 -Q option is specified.
2943 - The Configure() subsystem now reports if a test result is being
2944 taken from cache, and prints the standard output and error output
2945 of tests even when cached.
2947 - Configure() test results are now reported as "yes" or "no" instead of
2950 - Fixed traceback printing when calling the env.Configure() method
2951 instead of the Configure() global function.
2953 - The Configure() subsystem now caches build failures in a .sconsign
2954 file in the subdirectory, not a .cache file. This may cause
2955 tests to be re-executed the first time after you install 0.97.
2957 - Additional significant internal cleanups in the Configure() subsystem
2960 - Have the Qt Builder make uic-generated files dependent on the .ui.h
2961 file, if one exists.
2963 - Add a test to make sure that SCons source code does not contain
2964 try:-except: blocks that catch all errors, which potentially catch
2965 and mask keyboard interrupts.
2967 - Fix us of TargetSignatures('content') with the SConf subsystem.
2969 From Russell Yanofsky:
2971 - Add support for the Metrowerks Codewarrior compiler and linker
2976 RELEASE 0.96.1 - Mon, 23 Aug 2004 12:55:50 +0000
2978 From Craig Bachelor:
2980 - Handle white space in the executable Python path name within in MSVS
2981 project files by quoting the path.
2983 - Correct the format of a GUID string in a solution (.dsw) file so
2984 MSVS can correctly "build enable" a project.
2988 - Add a must_exist flag to Delete() to let the user control whether
2989 it's an error if the specified entry doesn't exist. The default
2990 behavior is now to silently do nothing if it doesn't exist.
2992 - Package up the new Platform/darwin.py, mistakenly left out of 0.96.
2994 - Make the scons.bat REM statements into @REM so they aren't printed.
2996 - Make the SCons packaging SConscript files platform independent.
3000 - Fix scanning of pre-compiled header (.pch) files for #includes,
3005 RELEASE 0.96 - Wed, 18 Aug 2004 13:36:40 +0000
3009 - Make the CacheDir() directory if it doesn't already exist.
3011 - Allow construction variable substitutions in $LIBS specifications.
3013 - Allow the emitter argument to a Builder() to be or expand to a list
3014 of emitter functions, which will be called in sequence.
3016 - Suppress null values in construction variables like $LIBS that use
3017 the internal _concat() function.
3019 - Remove .dll files from the construction variables searched for
3020 libraries that can be fed to Win32 compilers.
3022 From Chad Austin and Christoph Wiedemann:
3024 - Add support for a $RPATH variable to supply a list of directories
3025 to search for shared libraries when linking a program. Used by
3026 the GNU and IRIX linkers (gnulink and sgilink).
3030 - Restore the ability to do construction variable substitutions in all
3031 kinds of *PATH variables, even when the substitution returns a Node
3036 - Allow the Java() Builder to take more than one source directory.
3038 From Ralf W. Grosse-Kunstleve:
3040 - Have SConsignFile() use, by default, a custom "dblite.py" that we can
3041 control and guarantee to work on all Python versions (or nearly so).
3043 From Jonathan Gurley:
3045 - Add support for the newer "ifort" versions of the Intel Fortran
3050 - Make the new *FLAGS variable type work with copied Environments.
3052 From Chris Hoeppler:
3054 - Initialize the name of a Scanner.Classic scanner correctly.
3058 - Add support for the .dylib shared library suffix and the -dynamiclib
3059 linker option on Mac OS X.
3063 - Add an Execute() method for executing actions directly.
3065 - Support passing environment override keyword arguments to Command().
3067 - Fix use of $MSVS_IGNORE_IDE_PATHS, which was broken when we added
3068 support for $MSVS_USE_MFC_DIRS last release.
3070 - Make env.Append() and env.Prepend() act like the underlying Python
3071 behavior when the variable being appended to is a UserList object.
3073 - Fix a regression that prevented the Command() global function in
3074 0.95 from working with command-line strings as actions.
3076 - Fix checking out a file from a source code management system when
3077 the env.SourceCode() method was called with an individual file name
3078 or node, not a directory name or node.
3080 - Enhance the Task.make_ready() method to create a list of the
3081 out-of-date Nodes for the task for use by the wrapping interface.
3083 - Allow Scanners to pull the list of suffixes from the construction
3084 environment when the "skeys" keyword argument is a string containing
3085 a construction variable to be expanded.
3087 - Support new $CPPSUFFIXES, $DSUFFIXES $FORTRANSUFFIXES, and
3088 $IDLSUFFIXES. construction variables that contain the default list
3089 of suffixes to be scanned by a given type of scanner, allowing these
3090 suffix lists to be easily added to or overridden.
3092 - Speed up Node creation when calling a Builder by comparing whether two
3093 Environments are the same object, not if their underlying dictionaries
3096 - Add a --debug=explain option that reports the reason(s) why SCons
3097 thinks it must rebuild something.
3099 - Add support for functions that return platform-independent Actions
3100 to Chmod(), Copy(), Delete(), Mkdir(), Move() and Touch() files
3101 and/or directories. Like any other Actions, the returned Action
3102 object may be executed directly using the Execute() global function
3103 or env.Execute() environment method, or may be used as a Builder
3104 action or in an env.Command() action list.
3106 - Add support for the strfunction argument to all types of Actions:
3107 CommandAction, ListAction, and CommandGeneratorAction.
3109 - Speed up turning file system Nodes into strings by caching the
3110 values after we're finished reading the SConscript files.
3112 - Have ParseConfig() recognize and supporting adding the -Wa, -Wl,
3113 and -Wp, flags to ASFLAGS, LINKFLAGS and CPPFLAGS, respectively.
3115 - Change the .sconsign format and the checks for whether a Node is
3116 up-to-date to make dependency checks more efficient and correct.
3118 - Add wrapper Actions to SCons.Defaults for $ASCOM, $ASPPCOM, $LINKCOM,
3119 $SHLINKCOM, $ARCOM, $LEXCOM and $YACCCOM. This makes it possible
3120 to replace the default print behavior with a custom strfunction()
3123 - When a Node has been built, don't walk the whole tree back to delete
3124 the parents's implicit dependencies, let returning up the normal
3125 Taskmaster descent take care of it for us.
3127 - Add documented support for separate target_scanner and source_scanner
3128 arguments to Builder creation, which allows different scanners to
3129 be applied to source files
3131 - Don't re-install or (re-generate) .h files when a subsidiary #included
3132 .h file changes. This eliminates incorrect circular dependencies
3133 with .h files generated from other source files.
3135 - Slim down the internal Sig.Calculator class by eliminating methods
3136 whose functionality is now covered by Node methods.
3138 - Document use of the target_factory and source_factory keyword
3139 arguments when creating Builder objects. Enhance Dir Nodes so that
3140 they can be created with user-specified Builder objects.
3142 - Don't blow up with stack trace when the external $PATH environment
3145 - Make Builder calls return lists all the time, even if there's only
3146 one target. This keeps things consistent and easier to program to
3149 - Add a Flatten() function to make it easier to deal with the Builders
3150 all returning lists of targets, not individual targets.
3152 - Performance optimizations in Node.FS.__doLookup().
3154 - Man page fixes: formatting typos, misspellings, bad example.
3156 - User's Guide fixes: Fix the signatures of the various example
3157 *Options() calls. Triple-quote properly a multi-line Split example.
3159 - User's Guide additions: Chapter describing File and Directory
3160 Nodes. Section describing declarative nature of SCons functions in
3161 SConscript files. Better organization and clarification of points
3162 raised by Robert P. J. Day. Chapter describing SConf (Autoconf-like)
3163 functionality. Chapter describing how to install Python and
3164 SCons. Chapter describing Java builds.
3168 - Add a .win32 attribute to force file names to expand with
3169 Windows backslash path separators.
3171 - Fix escaping file names on command lines when the expansion is
3172 concatenated with another string.
3174 - Add support for Fortran 90 and Fortran 95. This adds $FORTRAN*
3175 variables that specify a default compiler, command-line, flags,
3176 etc. for all Fortran versions, plus separate $F90* and $F95*
3177 variables for when different compilers/flags/etc. must be specified
3178 for different Fortran versions.
3180 - Have individual tools that create libraries override the default
3181 $LIBPREFIX and $LIBSUFFIX values set by the platform. This makes
3182 it easier to use Microsoft Visual Studio tools on a CygWin platform.
3184 From Gary Oberbrunner:
3186 - Add a --debug=presub option to print actions prior to substitution.
3188 - Add a warning upon use of the override keywords "targets" and
3189 "sources" when calling Builders. These are usually mistakes which
3190 are otherwise silently (and confusingly) turned into construction
3193 - Try to find the ICL license file path name in the external environment
3194 and the registry before resorting to the hard-coded path name.
3196 - Add support for fetching command-line keyword=value arguments in
3197 order from an ARGLIST list.
3199 - Avoid stack traces when trying to read dangling symlinks.
3201 - Treat file "extensions" that only contain digits as part of the
3202 file basename. This supports version numbers as part of shared
3203 library names, for example.
3205 - Avoid problems when there are null entries (None or '') in tool
3208 - Add an example and explanation of how to use "tools = ['default', ..."
3209 when creating a construction environment.
3211 - Add a section describing File and Directory Nodes and some of their
3212 attributes and methods.
3214 - Have ParseConfig() add a returned -pthread flag to both $CCFLAGS
3217 - Fix some test portability issues on Mac OS X (darwin).
3221 - Fix a bug introduced in building shared libraries under MinGW.
3225 - Handling SCons exceptions according to Pythonic standards.
3227 - Fix test/chained-build.py on systems that execute within one second.
3229 - Fix tests on systems where 'ar' warns about archive creation.
3233 - Fix use of the --implicit-cache option with timestamp signatures.
3235 - If Visual Studio is installed, assume the C/C++ compiler, the linker
3236 and the MIDL compiler that comes with it are available, too.
3238 - Better error messages when evaluating a construction variable
3239 expansion yields a Python syntax error.
3241 - Change the generation of PDB files when using Visual Studio from
3242 compile time to link time.
3246 - Allow SConf.CheckLib() to search a list of libraries, like the
3247 Autoconf AC_SEARCH_LIBS macro.
3249 - Allow the env.WhereIs() method to take a "reject" argument to
3250 let it weed out specific path names.
3252 From Christoph Wiedemann:
3254 - Add new Moc() and Uic() Builders for more explicit control over
3255 Qt builds, plus new construction variables to control them:
3256 $QT_AUTOSCAN, $QT_DEBUG, $QT_MOCCXXPREFIX, $QT_MOCCXXSUFFIX,
3257 $QT_MOCHPREFIX, $QT_MOCHSUFFIX, $QT_UICDECLPREFIX, $QT_UICDECLSUFFIX,
3258 $QT_UICIMPLPREFIX, $QT_UICIMPLSUFFIX and $QT_UISUFFIX.
3260 - Add a new single_source keyword argument for Builders that enforces
3261 a single source file on calls to the Builder.
3265 RELEASE 0.95 - Mon, 08 Mar 2004 06:43:20 -0600
3269 - Replace print statements with calls to sys.stdout.write() so output
3270 lines stay together when -j is used.
3272 - Add portability fixes for a number of tests.
3274 - Accomodate the fact that Cygwin's os.path.normcase() lies about
3275 the underlying system being case-sensitive.
3277 - Fix an incorrect _concat() call in the $RCINCFLAGS definition for
3280 - Fix a problem with the msvc tool with Python versions prior to 2.3.
3282 - Add support for a "toolpath" Tool() and Environment keyword that
3283 allows Tool modules to be found in specified local directories.
3285 - Work around Cygwin Python's silly fiction that it's using a
3286 case-sensitive file system.
3288 - More robust handling of data in VCComponents.dat.
3290 - If the "env" command is available, spawn commands with the more
3291 general "env -" instead of "env -i".
3293 From Kerim Borchaev:
3295 - Fix a typo in a msvc.py's registry lookup: "VCComponents.dat", not
3298 From Chris Burghart:
3300 - Fix the ability to save/restore a PackageOption to a file.
3302 From Steve Christensen:
3304 - Update the MSVS .NET and MSVC 6.0/7.0 path detection.
3306 From David M. Cooke:
3308 - Make the Fortran scanner case-insensitive for the INCLUDE string.
3312 - If no version of MSVC is detected but the tool is specified,
3313 use the MSVC 6.0 paths by default.
3315 - Ignore any "6.1" version of MSVC found in the registry; this is a
3316 phony version number (created by later service packs?) and would
3317 throw off the logic if the user had any non-default paths configure.
3319 - Correctly detect if the user has independently configured the MSVC
3320 "include," "lib" or "path" in the registry and use the appropriate
3321 values. Previously, SCons would only use the values if all three
3322 were set in the registry.
3324 - Make sure side-effect nodes are prepare()d before building their
3325 corresponding target.
3327 - Preserve the ability to call BuildDir() multiple times with the
3328 same target and source directory arguments.
3332 - Add support for the Digital Mars "D" programming language.
3334 From Scott Lystig Fritchie:
3336 - Fix the ability to use a custom _concat() function in the
3337 construction environment when calling _stripixes().
3339 - Make the message about ignoring a missing SConscript file into a
3340 suppressable Warning, not a hard-coded sys.stderr.write().
3342 - If a builder can be called multiple times for a target (because
3343 the sources and overrides are identical, or it's a builder with the
3344 "multi" flag set), allow the builder to be called through multiple
3345 environments so long as the builders have the same signature for
3346 the environments in questions (that is, they're the same action).
3350 - When multiple targets are built by a single action, retrieve all
3351 of them from cache, not just the first target, and exec the build
3352 command if any of the targets isn't present in the cache.
3354 From Zephaniah Hull:
3356 - Fix command-line ARGUMENTS with multiple = in them.
3360 - Fix EnsureSConsVersion() so it checks against the SCons version,
3361 not the Python version, on Pythons with sys.version_info.
3363 - Don't swallow the AttributeError when someone uses an expansion like
3364 $TARGET.bak, so we can supply a more informative error message.
3366 - Fix an odd double-quote escape sequence in the man page.
3368 - Fix looking up a naked drive letter as a directory (Dir('C:')).
3370 - Support using File nodes in the LIBS construction variable.
3372 - Allow the LIBS construction variable to be a single string or File
3373 node, not a list, when only one library is needed.
3375 - Fix typos in the man page: JAVACHDIR => JARCHDIR; add "for_signature"
3376 to the __call__() example in the "Variable Substitution" section.
3378 - Correct error message spellings of "non-existant" to "non-existent."
3380 - When scanning for libraries to link with, don't append $LIBPREFIXES
3381 or $LIBSUFFIXES values to the $LIBS values if they're already present.
3383 - Add a ZIPCOMPRESSION construction variable to control whether the
3384 internal Python action for the Zip Builder compresses the file or
3385 not. The default value is zipfile.ZIP_DEFLATED, which generates
3388 - Refactor construction variable expansion to support recursive
3389 expansion of variables (e.g. CCFLAGS = "$CCFLAGS -g") without going
3390 into an infinite loop. Support this in all construction variable
3391 overrides, as well as when copying Environments.
3393 - Fix calling Configure() from more than one subsidiary SConscript file.
3395 - Fix the env.Action() method so it returns the correct type of
3396 Action for its argument(s).
3398 - Fix specifying .class files as input to JavaH with the .class suffix
3399 when they weren't generated using the Java Builder.
3401 - Make the check for whether all of the objects going into a
3402 SharedLibrary() are shared work even if the object was built in a
3405 - Supply meaningful error messages, not stack traces, if we try to add
3406 a non-Node as a source, dependency, or ignored dependency of a Node.
3408 - Generate MSVS Project files that re-invoke SCons properly regardless
3409 of whether the file was built via scons.bat or scons.py.
3410 (Thanks to Niall Douglas for contributing code and testing.)
3412 - Fix TestCmd.py, runtest.py and specific tests to accomodate being
3413 run from directories whose paths include white space.
3415 - Provide a more useful error message if a construction variable
3416 expansion contains a syntax error during evaluation.
3418 - Fix transparent checkout of implicit dependency files from SCCS
3421 - Added new --debug=count, --debug=memory and --debug=objects options.
3422 --debug=count and --debug=objects only print anything when run
3423 under Python 2.1 or later.
3425 - Deprecate the "overrides" keyword argument to Builder() creation
3426 in favor of using keyword argument values directly (like we do
3427 for builder execution and the like).
3429 - Always use the Builder overrides in substitutions, not just if
3430 there isn't a target-specific environment.
3432 - Add new "rsrcpath" and "rsrcdir" and attributes to $TARGET/$SOURCE,
3433 so Builder command lines can find things in Repository source
3434 directories when using BuildDir.
3436 - Fix the M4 Builder so that it chdirs to the Repository directory
3437 when the input file is in the source directory of a BuildDir.
3439 - Save memory at build time by allowing Nodes to delete their build
3440 environments after they've been built.
3442 - Add AppendUnique() and PrependUnique() Environment methods, which
3443 add values to construction variables like Append() and Prepend()
3444 do, but suppress any duplicate elements in the list.
3446 - Allow the 'qt' tool to still be used successfully from a copied
3447 Environment. The include and library directories previously ended up
3448 having the same string re-appended to the end, yielding an incorrect
3451 - Supply a more descriptive error message when the source for a target
3454 - Initialize all *FLAGS variables with objects do the right thing with
3455 appending flags as strings or lists.
3457 - Make things like ${TARGET.dir} work in *PATH construction variables.
3459 - Allow a $MSVS_USE_MFC_DIRS construction variable to control whether
3460 ATL and MFC directories are included in the default INCLUDE and
3463 - Document the dbm_module argument to the SConsignFile() function.
3467 - Add support for the bcc32, ilink32 and tlib Borland tools.
3471 - Supply an error message if the user tries to configure a BuildDir
3472 for a directory that already has one.
3474 - Remove documentation of the still-unimplemented -e option.
3476 - Add -H help text listing the legal --debug values.
3478 - Don't choke if a construction variable is a non-string value.
3480 - Build Type Libraries in the target directory, not the source
3483 - Add an appendix to the User's Guide showing how to accomplish
3484 various common tasks in Python.
3488 - Add support for Microsoft Visual Studio 2003 (version 7.1).
3490 - Evaluate $MSVSPROJECTSUFFIX and $MSVSSOLUTIONSUFFIX when the Builder
3491 is invoked, not when the tool is initialized.
3493 From Christoph Wiedemann:
3495 - When compiling Qt, make sure the moc_*.cc files are compiled using
3496 the flags from the environment used to specify the target, not
3497 the environment that first has the Qt Builders attached.
3501 RELEASE 0.94 - Fri, 07 Nov 2003 05:29:48 -0600
3503 From Hartmut Goebel:
3505 - Add several new types of canned functions to help create options:
3506 BoolOption(), EnumOption(), ListOption(), PackageOption(),
3511 - Fix use of CPPDEFINES with C++ source files.
3513 - Fix env.Append() when the operand is an object with a __cmp__()
3514 method (like a Scanner instance).
3516 - Fix subclassing the Environment and Scanner classes.
3518 - Add BUILD_TARGETS, COMMAND_LINE_TARGETS and DEFAULT_TARGETS variables.
3522 - SGI fixes: Fix C++ compilation, add a separate Tool/sgic++.py module.
3524 From Gary Oberbrunner:
3526 - Fix how the man page un-indents after examples in some browsers.
3530 - Fix the C and C++ tool specifications for AIX.
3534 RELEASE 0.93 - Thu, 23 Oct 2003 07:26:55 -0500
3538 - On POSIX, execute commands with the more modern os.spawnvpe()
3539 function, if it's available.
3541 - Scan .S, .spp and .SPP files for C preprocessor dependencies.
3543 - Refactor the Job.Parallel() class to use a thread pool without a
3544 condition variable. This improves parallel build performance and
3545 handles keyboard interrupts properly when -j is used.
3549 - Add support for a JARCHDIR variable to control changing to a
3550 directory using the jar -C option.
3552 - Add support for detecting Java manifest files when using jar,
3553 and specifying them using the jar m flag.
3555 - Fix some Python 2.2 specific things in various tool modules.
3557 - Support directories as build sources, so that a rebuild of a target
3558 can be triggered if anything underneath the directory changes.
3560 - Have the scons.bat and scons.py files look for the SCons modules
3561 in site-packages as well.
3563 From Christian Engel:
3565 - Support more flexible inclusion of separate C and C++ compilers.
3567 - Use package management tools on AIX and Solaris to find where
3568 the comilers are installed, and what version they are.
3570 - Add support for CCVERSION and CXXVERSION variables for a number
3571 of C and C++ compilers.
3575 - Add test cases for the new capabilities to run bibtex and to rerun
3578 From Ralf W. Grosse-Kunstleve:
3580 - Accomodate anydbm modules that don't have a sync() method.
3582 - Allow SConsignFile() to take an argument specifying the DBM
3585 From Stephen Kennedy:
3587 - Add support for a configurable global .sconsign.dbm file which
3588 can be used to avoid cluttering each directory with an individual
3593 - Fix (re-)scanning of dependencies in generated or installed
3598 - The -Q option suppressed too many messages; fix it so that it only
3599 suppresses the Reading/Building messages.
3601 - Support #include when there's no space before the opening quote
3604 - Accomodate alphanumeric version strings in EnsurePythonVersion().
3606 - Support arbitrary expansion of construction variables within
3607 file and directory arguments to Builder calls and Environment methods.
3609 - Add Environment-method versions of the following global functions:
3610 Action(), AddPostAction(), AddPreAction(), Alias(), Builder(),
3611 BuildDir(), CacheDir(), Clean(), Configure(), Default(),
3612 EnsurePythonVersion(), EnsureSConsVersion(), Environment(),
3613 Exit(), Export(), FindFile(), GetBuildPath(), GetOption(), Help(),
3614 Import(), Literal(), Local(), Platform(), Repository(), Scanner(),
3615 SConscriptChdir(), SConsignFile(), SetOption(), SourceSignatures(),
3616 Split(), TargetSignatures(), Tool(), Value().
3618 - Add the following global functions that correspond to the same-named
3619 Environment methods: AlwaysBuild(), Command(), Depends(), Ignore(),
3620 Install(), InstallAs(), Precious(), SideEffect() and SourceCode().
3622 - Add the following global functions that correspond to the default
3623 Builder methods supported by SCons: CFile(), CXXFile(), DVI(), Jar(),
3624 Java(), JavaH(), Library(), M4(), MSVSProject(), Object(), PCH(),
3625 PDF(), PostScript(), Program(), RES(), RMIC(), SharedLibrary(),
3626 SharedObject(), StaticLibrary(), StaticObject(), Tar(), TypeLibrary()
3629 - Rearrange the man page to show construction environment methods and
3630 global functions in the same list, and to explain the difference.
3632 - Alphabetize the explanations of the builder methods in the man page.
3634 - Rename the Environment.Environment class to Enviroment.Base.
3635 Allow the wrapping interface to extend an Environment by using its own
3636 subclass of Environment.Base and setting a new Environment.Environment
3637 variable as the calling entry point.
3639 - Deprecate the ParseConfig() global function in favor of a same-named
3640 construction environment method.
3642 - Allow the Environment.WhereIs() method to take explicit path and
3643 pathext arguments (like the underlying SCons.Util.WhereIs() function).
3645 - Remove the long-obsolete {Get,Set}CommandHandler() functions.
3647 - Enhance env.Append() to suppress null values when appropriate.
3649 - Fix ParseConfig() so it works regardless of initial construction
3652 Extend CheckHeader(), CheckCHeader(), CheckCXXHeader() and
3653 CheckLibWithHeader() to accept a list of header files that will be
3654 #included in the test. The last one in the list is assumed to be
3655 the one being checked for. (Prototype code contributed by Gerard
3656 Patel and Niall Douglas).
3658 - Supply a warning when -j is used and threading isn't built in to
3659 the current version of Python.
3661 - First release of the User's Guide (finally, and despite a lot
3662 of things still missing from it...).
3666 - Generalize the action for .tex files so that it will decide whether
3667 a file is TeX or LaTeX, check the .aux output to decide if it should
3668 run bibtex, and check the .log output to re-run LaTeX if needed.
3670 From Bram Moolenaar:
3672 - Split the non-SCons-specific functionality from SConf.py to a new,
3673 re-usable Conftest.py module.
3675 From Gary Oberbrunner:
3677 - Allow a directory to be the target or source or dependency of a
3678 Depends(), Ignore(), Precious() or SideEffect() call.
3682 - Use the %{_mandir} macro when building our RPM package.
3684 From Marko Rauhamaa:
3686 - Have the closing message say "...terminated because of errors" if
3691 - On Win32 systems, only use "rm" to delete files if Cygwin is being
3692 used. ("rm" doesn't understand Win32-format path names.)
3694 From Christoph Wiedemann:
3696 - Fix test/SWIG.py to find the Python include directory in all cases.
3698 - Fix a bug in detection of Qt installed on the local system.
3700 - Support returning Python 2.3 BooleanType values from Configure checks.
3702 - Provide an error message if someone mistakenly tries to call a
3703 Configure check from within a Builder function.
3705 - Support calling a Builder when a Configure context is still open.
3707 - Handle interrupts better by eliminating all try:-except: blocks
3708 which caught any and all exceptions, including KeyboardInterrupt.
3710 - Add a --duplicate= option to control how files are duplicated.
3714 RELEASE 0.92 - Wed, 20 Aug 2003 03:45:28 -0500
3716 From Charles Crain and Gary Oberbrunner:
3718 - Fix Tool import problems with the Intel and PharLap linkers.
3722 - Refactor the DictCmdGenerator class to be a Selector subclass.
3724 - Allow the DefaultEnvironment() function to take arguments and pass
3725 them to instantiation of the default construction environment.
3727 - Update the Debian package so it uses Python 2.2 and more closely
3728 resembles the currently official Debian packaging info.
3732 - When the yacc -d flag is used, take the .h file base name from the
3733 target .c file, not the source (matching what yacc does).
3737 RELEASE 0.91 - Thu, 14 Aug 2003 13:00:44 -0500
3741 - Support specifying a list of tools when calling Environment.Copy().
3743 - Give a Value Nodes a timestamp of the system time when they're
3744 created, so they'll work when using timestamp-based signatures.
3746 - Add a DefaultEnvironment() function that only creates a default
3747 environment on-demand (for fetching source files, e.g.).
3749 - Portability fix for test/M4.py.
3753 - Tighten up the scons -H help output.
3755 - When the input yacc file ends in .yy and the -d flag is specified,
3756 recognize that a .hpp file (not a .h file) will be created.
3758 - Make builder prefixes work correctly when deducing a target
3759 from a source file name in another directory.
3761 - Documentation fixes: typo in the man page; explain up-front about
3762 not propagating the external environment.
3764 - Use "cvs co -d" instead of "cvs co -p >" when checking out something
3765 from CVS with a specified module name. This avoids zero-length
3766 files when there is a checkout error.
3768 - Add an "sconsign" script to print the contents of .sconsign files.
3770 - Speed up maintaining the various lists of Node children by using
3771 dictionaries to avoid "x in list" searches.
3773 - Cache the computed list of Node children minus those being Ignored
3774 so it's only calculated once.
3776 - Fix use of the --cache-show option when building a Program()
3777 (or using any other arbitrary action) by making sure all Action
3778 instances have strfunction() methods.
3780 - Allow the source of Command() to be a directory.
3782 - Better error handling of things like raw TypeErrors in SConscripts.
3784 - When installing using "setup.py install --prefix=", suppress the
3785 distutils warning message about adding the (incorrect) library

3807 - Allow the "prefix" and "suffix" attributes of a Builder to be
3808 callable objects that return generated strings, or dictionaries
3809 that map a source file suffix to the right prefix/suffix.

3911 - SCons now enforces (with an error) that construction variables
3912 must have the same form as valid Python identifiers.
3914 - Fix man page bugs: remove duplicate AddPostAction() description;
3915 document no_import_lib; mention that CPPFLAGS does not contain

4027 - Check out CVS source files using POSIX path names (forward slashes
4028 as separators) even on Win32.

4082 - Fix a number of tests that searched for a Fortran compiler using the
4083 external PATH instead of what SCons would use.
4085 - Fix the interaction of SideEffect() and BuildDir() so that (for
4086 example) PDB files get put correctly in a BuildDir().

4111 From Christoph Wiedemann:
4113 - Integrate David Snopek's "Autoscons" code as the new SConf
4114 configuration subsystem, including caching of values between
4115 runs (using normal SCons dependency mechanisms), tests, and
4120 RELEASE 0.13 - Mon, 31 Mar 2003 20:22:00 -0600
4124 - Fix a bug when BuildDir(duplicate=0) is used and SConscript
4125 files are called from within other SConscript files.
4127 - Support (older) versions of Perforce which don't set the Windows
4132 RELEASE 0.12 - Thu, 27 Mar 2003 23:52:09 -0600
4136 - Added support for the Perforce source code management system.
4138 - Fix str(Node.FS) so that it returns a path relative to the calling
4139 SConscript file's directory, not the top-level directory.
4141 - Added support for a separate src_dir argument to SConscript()
4142 that allows explicit specification of where the source files
4143 for an SConscript file can be found.
4145 - Support more easily re-usable flavors of command generators by
4146 calling callable variables when strings are expanded.
4150 - Added an INSTALL construction variable that can be set to a function
4151 to control how the Install() and InstallAs() Builders install files.
4152 The default INSTALL function now copies, not links, files.
4154 - Remove deprecated features: the "name" argument to Builder objects,
4155 and the Environment.Update() method.
4157 - Add an Environment.SourceCode() method to support fetching files
4158 from source code systems. Add factory methods that create Builders
4159 to support BitKeeper, CVS, RCS, and SCCS. Add support for fetching
4160 files from RCS or SCCS transparently (like GNU Make).
4162 - Make the internal to_String() function more efficient.
4164 - Make the error message the same as other build errors when there's a
4165 problem unlinking a target file in preparation for it being built.

4168 warn if the user tries to set them in a construction environment.
4170 - Add support for Tar and Zip files.
4172 - Better documentation of the different ways to export variables to a
4173 subsidiary SConscript file. Fix documentation bugs in a tools

4177 - Support fetching arbitrary files from the TARGETS or SOURCES lists
4178 (e.g. ${SOURCES[2]}) when calculating the build signature of a
4181 - Don't silently swallow exceptions thrown by Scanners (or other
4182 exceptions while finding a node's dependent children).
4184 - Push files to CacheDir() before calling the superclass built()
4185 method (which may clear the build signature as part of clearing
4186 cached implicit dependencies, if the file has a source scanner).
4187 (Bug reported by Jeff Petkau.)
4189 - Raise an internal error if we attempt to push a file to CacheDir()
4190 with a build signature of None.
4192 - Add an explicit Exit() function for terminating early.
4194 - Change the documentation to correctly describe that the -f option
4195 doesn't change to the directory in which the specified file lives.
4197 - Support changing directories locally with SConscript directory
4198 path names relative to any SConstruct file specified with -f.
4199 This allows you to build in another directory by simply changing
4200 there and pointing at the SConstruct file in another directory.
4202 - Change the default SConscriptChdir() behavior to change to the
4203 SConscript directory while it's being read.
4205 - Fix an exception thrown when the -U option was used with no

4209 when used in a source directory.
4213 - Add SharedObject() support to the masm tool.
4215 - Fix WhereIs() to return normalized paths.
4219 - Don't copy a built file to a CacheDir() if it's already there.
4221 - Avoid partial copies of built files in a CacheDir() by copying
4222 to a temporary file and renaming.
4226 - Fix incorrect dependency-cycle errors when an Aliased source doesn't
4231 RELEASE 0.11 - Tue, 11 Feb 2003 05:24:33 -0600
4235 - Add support for IRIX and the SGI MIPSPro tool chain.
4237 - Support using the MSVC tool chain when running Cygwin Python.
4241 - Avoid losing signal bits in the exit status from a command,
4242 helping terminate builds on interrupt (CTRL+C).
4246 - Added new AddPreAction() and AddPostAction() functions that support
4247 taking additional actions before or after building specific targets.
4249 - Add support for the PharLap ETS tool chain.
4253 - Allow Python function Actions to specify a list of construction
4254 variables that should be included in the Action's signature.

4257 and suffix, even when using the GNU linker.
4258 (Bug reported by Neal Becker.)
4260 - Use DOS-standard CR-LF line endings in the scons.bat file.
4261 (Bug reported by Gary Ruben.)
4263 - Doc changes: Eliminate description of deprecated "name" keyword
4264 argument from Builder definition (reported by Gary Ruben).
4266 - Support using env.Append() on BUILDERS (and other dictionaries).
4267 (Bug reported by Bj=F6rn Bylander.)
4269 - Setting the BUILDERS construction variable now properly clears
4270 the previous Builder attributes from the construction Environment.
4271 (Bug reported by Bj=F6rn Bylander.)
4273 - Fix adding a prefix to a file when the target isn't specified.
4274 (Bug reported by Esa Ilari Vuokko.)
4276 - Clean up error messages from problems duplicating into read-only
4277 BuildDir directories or into read-only files.
4279 - Add a CommandAction.strfunction() method, and add an "env" argument
4280 to the FunctionAction.strfunction() method, so that all Action
4281 objects have strfunction() methods, and the functions for building
4282 and returning a string both take the same arguments.
4284 - Add support for new CacheDir() functionality to share derived files
4285 between builds, with related options --cache-disable, --cache-force,
4288 - Change the default behavior when no targets are specified to build
4289 everything in the current directory and below (like Make). This
4290 can be disabled by specifying Default(None) in an SConscript.
4292 - Revamp SCons installation to fix a case-sensitive installation
4293 on Win32 systems, and to add SCons-specific --standard-lib,
4294 --standalone-lib, and --version-lib options for easier user
4295 control of where the libraries get installed.
4297 - Fix the ability to directly import and use Platform and Tool modules
4298 that have been implicitly imported into an Environment().
4300 - Add support for allowing an embedding interface to annotate a node
4303 - Extend the SConscript() function to accept build_dir and duplicate
4304 keyword arguments that function like a BuildDir() call.
4308 - Fix the output of -c -n when directories are involved, so it
4313 - Use a different shared object suffix (.os) when using gcc so shared
4314 and static objects can exist side-by-side in the same directory.
4316 - Allow the same object files on Win32 to be linked into either
4317 shared or static libraries.
4319 - Cache implicit cache values when using --implicit-cache.
4323 RELEASE 0.10 - Thu, 16 Jan 2003 04:11:46 -0600
4325 From Derrick 'dman' Hudson:
4327 - Support Repositories on other file systems by symlinking or
4328 copying files when hard linking won't work.
4332 - Remove Python bytecode (*.pyc) files from the scons-local packages.
4334 - Have FunctionActions print a description of what they're doing
4335 (a representation of the Python call).
4337 - Fix the Install() method so that, like other actions, it prints
4338 what would have happened when the -n option is used.
4340 - Don't create duplicate source files in a BuildDir when the -n
4343 - Refactor the Scanner interface to eliminate unnecessary Scanner
4344 calls and make it easier to write efficient scanners.
4346 - Added a "recursive" flag to Scanner creation that specifies the
4347 Scanner should be invoked recursively on dependency files returned
4350 - Significant performance improvement from using a more efficient
4351 check, throughout the code, for whether a Node has a Builder.
4353 - Fix specifying only the source file to MultiStepBuilders such as
4354 the Program Builder. (Bug reported by Dean Bair.)
4356 - Fix an exception when building from a file with the same basename as
4357 the subdirectory in which it lives. (Bug reported by Gerard Patel.)
4359 - Fix automatic deduction of a target file name when there are
4360 multiple source files specified; the target is now deduced from just
4361 the first source file in the list.
4363 - Documentation fixes: better initial explanation of SConscript files;
4364 fix a misformatted "table" in the StaticObject explanation.
4366 From Steven Knight and Steve Leblanc:
4368 - Fix the -c option so it will remove symlinks.
4372 - Add a Clean() method to support removing user-specified targets
4373 when using the -c option.
4375 - Add a development script for running SCons through PyChecker.
4377 - Clean up things found by PyChecker (mostly unnecessary imports).
4379 - Add a script to use HappyDoc to create HTML class documentation.
4383 - Make the Environment.get() method return None by default.
4387 - Add SetJobs() and GetJobs() methods to allow configuration of the
4388 number of default jobs (still overridden by -j).
4390 - Convert the .sconsign file format from ASCII to a pickled Python
4393 - Error message cleanups: Made consistent the format of error
4394 messages (now all start with "scons: ***") and warning messages (now
4395 all start with "scons: warning:"). Caught more cases with the "Do
4396 not know how to build" error message.
4398 - Added support for the MinGW tool chain.
4400 - Added a --debug=includes option.
4404 RELEASE 0.09 - Thu, 5 Dec 2002 04:48:25 -0600

4425 From Charles Crain and Steven Knight:
4427 - Add Repository() functionality, including the -Y option.
4431 - Fix auto-deduction of target names so that deduced targets end
4432 up in the same subdirectory as the source.
4434 - Don't remove source files specified on the command line!
4436 - Suport the Intel Fortran Compiler (ifl.exe).
4438 - Supply an error message if there are no command-line or
4439 Default() targets specified.
4441 - Fix the ASPPCOM values for the GNU assembler.
4442 (Bug reported by Brett Polivka.)
4444 - Fix an exception thrown when a Default() directory was specified
4445 when using the -U option.
4447 - Issue a warning when -c can't remove a target.
4449 - Eliminate unnecessary Scanner calls by checking for the
4450 existence of a file before scanning it. (This adds a generic
4451 hook to check an arbitrary condition before scanning.)
4453 - Add explicit messages to tell when we're "Reading SConscript files
4454 ...," "done reading SConscript files," "Building targets," and
4455 "done building targets." Add a -Q option to supress these.
4457 - Add separate $SHOBJPREFIX and $SHOBJSUFFIX construction variables
4458 (by default, the same as $OBJPREFIX and $OBJSUFFIX).
4460 - Add Make-like error messages when asked to build a source file,
4461 and before trying to build a file that doesn't have all its source
4462 files (including when an invalid drive letter is used on WIN32).
4464 - Add an scons-local-{version} package (in both .tar.gz and .zip
4465 flavors) to help people who want to ship SCons as a stand-alone
4466 build tool in their software packages.
4468 - Prevent SCons from unlinking files in certain situations when
4469 the -n option is used.
4471 - Change the name of Tool/lib.py to Tool/mslib.py.
4473 From Steven Knight and Anthony Roach:
4475 - Man page: document the fact that Builder calls return Node objects.
4479 - Refactor option processing to use our own version of Greg Ward's
4480 Optik module, modified to run under Python 1.5.2.
4482 - Add a ParseConfig() command to modify an environment based on
4483 parsing output from a *-config command.
4487 - Fix interpretation of '#/../foo' on Win32 systems.
4491 - Fixed use of command lines with spaces in their arguments,
4492 and use of Nodes with spaces in their string representation.
4494 - Make access and modification times of files in a BuildDir match
4495 the source file, even when hard linking isn't available.
4497 - Make -U be case insensitive on Win32 systems.
4499 - Issue a warning and continue when finding a corrupt .sconsign file.
4501 - Fix using an alias as a dependency of a target so that if one of the
4502 alias' dependencies gets rebuilt, the resulting target will, too.
4504 - Fix differently ordered targets causing unnecessary rebuilds
4505 on case insensitive systems.
4507 - Use os.system() to execute external commands whenever the "env"
4508 utility is available, which is much faster than fork()/exec(),
4509 and fixes the -j option on several platforms.
4511 - Fix use of -j with multiple targets.
4513 - Add an Options() object for friendlier accomodation of command-
4516 - Add support for Microsoft VC++ precompiled header (.pch) files,

4519 - Don't compute the $_CPPINCFLAGS, $_F77INCFLAGS, $_LIBFLAGS and
4520 $_LIBDIRFLAGS variables each time a command is executed, define
4521 them so they're computed only as needed. Add a new _concat
4522 function to the Environment that allows people to define their
4523 own similar variables.
4525 - Fix dependency scans when $LIBS is overridden.
4527 - Add EnsurePythonVersion() and EnsureSConsVersion() functions.
4529 - Fix the overly-verbose stack trace on ListBuilder build errors.
4531 - Add a SetContentSignatureType() function, allowing use of file
4532 timestamps instead of MD5 signatures.
4534 - Make -U and Default('source') fail gracefully.
4536 - Allow the File() and Dir() methods to take a path-name string as
4537 the starting directory, in addition to a Dir object.

4540 and ESCAPE construction variables.
4542 - Allow construction variables to be overridden when a Builder
4547 - Dynamically check for the existence of utilities with which to
4548 initialize Environments by default.
4552 RELEASE 0.08 - Mon, 15 Jul 2002 12:08:51 -0500
4556 - Fixed a bug with relative CPPPATH dirs when using BuildDir().
4557 (Bug reported by Bob Summerwill.)
4559 - Added a warnings framework and a --warn option to enable or
4562 - Make the C scanner warn users if files referenced by #include
4563 directives cannot be found and --warn=dependency is specified.
4565 - The BUILDERS construction variable should now be a dictionary
4566 that maps builder names to actions. Existing uses of lists,
4567 and the Builder name= keyword argument, generate warnings
4568 about use of deprecated features.
4570 - Removed the "shared" keyword argument from the Object and
4573 - Added separated StaticObject, SharedObject, StaticLibrary and
4574 SharedLibrary builders. Made Object and Library synonyms for
4575 StaticObject and StaticLibrary, respectively.

4584 - Allow a build directory to be outside of the SConstruct tree.
4586 - Add a FindFile() function that searches for a file node with a
4589 - Add $CPPFLAGS to the shared-object command lines for g++ and gcc.
4591 From Charles Crain and Steven Knight:
4593 - Add a "tools=" keyword argument to Environment instantiation,
4594 and a separate Tools() method, for more flexible specification
4595 of tool-specific environment changes.
4599 - Add a "platform=" keyword argument to Environment instantiation,
4600 and a separate Platform() method, for more flexible specification
4601 of platform-specific environment changes.
4603 - Updated README instructions and setup.py code to catch an
4604 installation failure from not having distutils installed.
4606 - Add descriptions to the -H help text for -D, -u and -U so
4607 people can tell them apart.
4609 - Remove the old feature of automatically splitting strings
4610 of file names on white space.
4612 - Add a dependency Scanner for native Fortran "include" statements,
4613 using a new "F77PATH" construction variable.
4615 - Fix C #include scanning to detect file names with characters like
4618 - Add more specific version / build output to the -v option.
4620 - Add support for the GNU as, Microsoft masm, and nasm assemblers.
4622 - Allow the "target" argument to a Builder call to be omitted, in
4623 which case the target(s) are deduced from the source file(s) and the
4624 Builder's specified suffix.
4626 - Add a tar archive builder.
4628 - Add preliminary support for the OS/2 Platform, including the icc
4633 - Fix --implicit-cache if the scanner returns an empty list.
4637 - Add a "multi" keyword argument to Builder creation that specifies
4638 it's okay to call the builder multiple times for a target.
4640 - Set a "multi" on Aliases so multiple calls will append to an Alias.
4642 - Fix emitter functions' use of path names when using BuildDir or
4645 - Fix --implicit-cache causing redundant rebuilds when the header
4648 - Fix --implicit-cache when a file has no implicit dependencies and
4649 its source is generated.
4651 - Make the drive letters on Windows always be the same case, so that
4652 changes in the case of drive letters don't cause a rebuild.
4654 - Fall back to importing the SCons.TimeStamp module if the SCons.MD5
4655 module can't be imported.
4657 - Fix interrupt handling to guarantee that a single interrupt will
4658 halt SCons both when using -j and not.
4660 - Fix .sconsign signature storage so that output files of one build
4661 can be safely used as input files to another build.
4663 - Added a --debug=time option to print SCons execution times.
4665 - Print an error message if a file can't be unlinked before being
4666 built, rather than just silently terminating the build.
4668 - Add a SideEffect() method that can be used to tell the build
4669 engine that a given file is created as a side effect of building
4670 a target. A file can be specified as a side effect of more than
4671 one build comand, in which case the commands will not be executed
4674 - Significant performance gains from not using our own version of
4675 the inefficient stock os.path.splitext() method, caching source
4676 suffix computation, code cleanup in MultiStepBuilder.__call__(),
4677 and replicating some logic in scons_subst().
4679 - Add --implicit-deps-changed and --implicit-deps-unchanged options.
4681 - Add a GetLaunchDir() function.
4683 - Add a SetBuildSignatureType() function.
4687 - Add an Append() method to Environments, to append values to
4688 construction variables.
4690 - Change the name of Update() to Replace(). Keep Update() as a
4691 deprecated synonym, at least for now.
4693 From Terrel Shumway:
4695 - Use a $PYTHON construction variable, initialized to sys.executable,
4696 when using Python to build parts of the SCons packages.
4698 - Use sys.prefix, not sys.exec_prefix, to find pdb.py.
4702 RELEASE 0.07 - Thu, 2 May 2002 13:37:16 -0500
4706 - Changes to build SCons packages on IRIX (and other *NIces).
4708 - Don't create a directory Node when a file already exists there,
4711 - Add 'dirs' and 'names' keyword arguments to SConscript for
4712 easier specification of subsidiary SConscript files.
4716 - Internal cleanup of environment passing to function Actions.
4718 - Builders can now take arbitrary keyword arguments to create
4719 attributes to be passed to: command generator functions,
4720 FunctionAction functions, Builder emitter functions (below),
4721 and prefix/suffix generator functions (below).
4723 - Command generator functions can now return ANYTHING that can be
4724 converted into an Action (a function, a string, a CommandGenerator
4725 instance, even an ActionBase instance).
4727 - Actions now call get_contents() with the actual target and source
4728 nodes used for the build.
4730 - A new DictCmdGenerator class replaces CompositeBuilder to support
4731 more flexible Builder behavior internally.
4733 - Builders can now take an emitter= keyword argument. An emitter
4734 is a function that takes target, source, and env argument, then
4735 return a 2-tuple of (new sources, new targets). The emitter is
4736 called when the Builder is __call__'ed, allowing a user to modify
4737 source and target lists.
4739 - The prefix, suffix and src_suffix Builder arguments now take a
4740 callable as well a string. The callable is passed the Environment
4741 and any extra Builder keyword arguments and is expected to return
4742 the appropriate prefix or suffix.
4744 - CommandActions can now be a string, a list of command + argument
4745 strings, or a list of commands (strings or lists).
4747 - Added shared library support. The Object and Library Builders now
4748 take a "shared=1" keyword argument to specify that a shared object
4749 or shared library should be built. It is an error to try to build
4750 static objects into a shared library or vice versa.
4752 - Win32 support for .def files has been added. Added the Win32-specific
4753 construction variables $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
4754 $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX. When building a .dll,
4755 the new construction variable $WIN32_INSERT_DEF, controls whether
4756 the appropriately-named .def file is inserted into the target
4757 list (if not already present). A .lib file is always added to
4758 a Library build if not present in the list of targets.
4760 - ListBuilder now passes all targets to the action, not just the first.
4762 - Fix so that -c now deletes generated yacc .h files.
4764 - Builder actions and emitter functions can now be initialized, through
4765 construction variables, to things other than strings.
4767 - Make top-relative '#/dir' lookups work like '#dir'.
4769 - Fix for relative CPPPATH directories in subsidiary SConscript files
4772 - Add a for_signature argument to command generators, so that
4773 generators that need to can return distinct values for the
4774 command signature and for executing the command.
4778 - Create a better scons.bat file from a py2bat.py script on the Python
4779 mailing list two years ago (modeled after pl2bat.pl).
4783 - Fix so that -c -n does *not* remove the targets!
4785 - Man page: Add a hierarchical libraries + Program example.
4787 - Support long MSVC linker command lines through a builder action
4788 that writes to a temporary file and uses the magic MSVC "link @file"
4789 argument syntax if the line is longer than 2K characters.
4791 - Fix F77 command-line options on Win32 (use /Fo instead of -o).
4793 - Use the same action to build from .c (lower case) and .C (upper
4794 case) files on case-insensitive systems like Win32.
4796 - Support building a PDF file directly from a TeX or LaTeX file
4797 using pdftex or pdflatex.
4799 - Add a -x option to runtest.py to specify the script being tested.
4800 A -X option indicates it's an executable, not a script to feed
4801 to the Python interpreter.
4803 - Add a Split() function (identical to SCons.Util.argmunge()) for use
4804 in the next release, when Builders will no longer automatically split
4805 strings on white space.
4809 - Add the SConscriptChdir() method.
4813 - Fix --debug=tree when used with directory targets.
4815 - Significant internal restructuring of Scanners and Taskmaster.
4817 - Added new --debug=dtree option.
4819 - Fixes for --profile option.
4821 - Performance improvement in construction variable substitution.
4823 - Implemented caching of content signatures, plus added --max-drift
4824 option to control caching.
4826 - Implemented caching of dependency signatures, enabled by new
4827 --implicit-cache option.
4829 - Added abspath construction variable modifier.
4831 - Added $SOURCE variable as a synonym for $SOURCES[0].
4833 - Write out .sconsign files on error or interrupt so intermediate
4834 build results are saved.
4836 - Change the -U option to -D. Make a new -U that builds just the
4837 targets from the local SConscript file.
4839 - Fixed use of sys.path so Python modules can be imported from
4840 the SConscript directory.
4842 - Fix for using Aliases with the -u, -U and -D options.
4844 - Fix so that Nodes can be passed to SConscript files.
4848 - Changes for official Debian packaging.
4852 RELEASE 0.06 - Thu, 28 Mar 2002 01:24:29 -0600
4856 - Fix command generators to expand construction variables.
4858 - Make FunctionAction arguments be Nodes, not strings.
4860 From Stephen Kennedy:
4862 - Performance: Use a dictionary, not a list, for a Node's parents.
4866 - Add .zip files to the packages we build.
4868 - Man page: document LIBS, fix a typo, document ARGUMENTS.
4870 - Added RANLIB and RANLIBFLAGS construction variables. Only use them
4871 in ARCOM if there's a "ranlib" program on the system.
4873 - Add a configurable CFILESUFFIX for the Builder of .l and .y files
4876 - Add a CXXFile Builder that turns .ll and .yy files into .cc files
4877 (configurable via a CXXFILESUFFIX construction variable).
4879 - Use the POSIX-standard lex -t flag, not the GNU-specific -o flag.
4880 (Bug reported by Russell Christensen.)
4882 - Fixed an exception when CPPPATH or LIBPATH is a null string.
4883 (Bug reported by Richard Kiss.)
4885 - Add a --profile=FILE option to make profiling SCons easier.
4887 - Modify the new DVI builder to create .dvi files from LaTeX (.ltx
4890 - Add support for Aliases (phony targets).
4892 - Add a WhereIs() method for searching for path names to executables.
4894 - Add PDF and PostScript document builders.
4896 - Add support for compiling Fortran programs from a variety of
4897 suffixes (a la GNU Make): .f, .F, .for, .FOR, .fpp and .FPP
4899 - Support a CPPFLAGS variable on all default commands that use the
4904 - Add support for the -U option.
4906 - Allow CPPPATH, LIBPATH and LIBS to be specified as white-space
4909 - Add a document builder to create .dvi files from TeX (.tex) files.
4913 - Fix: Construction variables with values of 0 were incorrectly
4916 - Support env['VAR'] to fetch construction variable values.
4918 - Man page: document Precious().
4922 RELEASE 0.05 - Thu, 21 Feb 2002 16:50:03 -0600
4926 - Set PROGSUFFIX to .exe under Cygwin.
4930 - Allow a library to specified as a command-line source file, not just
4931 in the LIBS construction variable.
4933 - Compensate for a bug in os.path.normpath() that returns '' for './'
4936 - More performance optimizations: cache #include lines from files,
4937 eliminate unnecessary calls.
4939 - If a prefix or suffix contains white space, treat the resulting
4940 concatenation as separate arguments.
4942 - Fix irregularities in the way we fetch DevStudio information from
4943 the Windows registry, and in our registry error handling.
4947 - Flush stdout after print so it intermixes correctly with stderr
4950 - Allow Scanners to return a list of strings, and document how to
4951 write your own Scanners.
4953 - Look up implicit (scanned) dependencies relative to the directory
4954 of file being scanned.
4956 - Make writing .sconsign files more robust by first trying to write
4957 to a temp file that gets renamed.
4959 - Create all of the directories for a list of targets before trying
4960 to build any of the targets.
4962 - WIN32 portability fixes in tests.
4964 - Allow the list of variables exported to an SConscript file to be
4967 - Document the overlooked LIBPATH construction variable.
4968 (Bug reported by Eicke Godehardt.)
4970 - Fix so that Ignore() ignores indirect, implicit dependencies
4971 (included files), not just direct dependencies.
4973 - Put the man page in the Debian distribution.
4975 - Run HTML docs through tidy to clean up the HTML (for Konqueror).
4977 - Add preliminary support for Unicode strings.
4979 - Efficiency: don't scan dependencies more than once during the

5005 RELEASE 0.04 - Wed, 30 Jan 2002 11:09:42 -0600
5009 - Significant performance improvements in the Node.FS and
5012 - Fix signatures of binary files on Win32 systems.
5014 - Allow LIBS and LIBPATH to be strings, not just arrays.
5016 - Print a traceback if a Python-function builder throws an exception.
5020 - Fix using a directory as a Default(), and allow Default() to
5021 support white space in file names for strings in arrays.
5023 - Man page updates: corrected some mistakes, documented various
5024 missing Environment methods, alphabetized the construction
5025 variables and other functions, defined begin and end macros for
5026 the example sections, regularized white space separation, fixed
5027 the use of Export() in the Multiple Variants example.
5029 - Function action fixes: None is now a successful return value.
5030 Exceptions are now reported. Document function actions.
5032 - Add 'Action' and 'Scanner' to the global keywords so SConscript
5033 files can use them too.
5035 - Removed the Wrapper class between Nodes and Walkers.
5037 - Add examples using Library, LIBS, and LIBPATH.
5039 - The C Scanner now always returns a sorted list of dependencies
5040 so order changes don't cause unnecessary rebuilds.
5042 - Strip $(-$) bracketed text from command lines. Use this to
5043 surround $_INCDIRS and $_LIBDIRS so we don't rebuild in response
5044 to changes to -I or -L options.
5046 - Add the Ignore() method to ignore dependencies.
5048 - Provide an error message when a nonexistent target is specified
5049 on the command line.
5051 - Remove targets before building them, and add an Environment
5052 Precious() method to override that.
5054 - Eliminate redundant calls to the same builder when the target is a
5055 list of targets: Add a ListBuilder class that wraps Builders to
5056 handle lists atomically. Extend the Task class to support building
5057 and updating multiple targets in a single Task. Simplify the
5058 interface between Task and Taskmaster.
5060 - Add a --debug=pdb option to re-run SCons under the Python debugger.
5062 - Only compute a build signature once for each node.
5064 - Changes to our sys.path[] manipulation to support installation into
5065 an arbitrary --prefix value.

5073 RELEASE 0.03 - Fri, 11 Jan 2002 01:09:30 -0600
5077 - Performance improvements in the Node.FS and Sig.Calculator classes.
5079 - Add the InstallAs() method.
5081 - Execute commands through an external interpreter (sh, cmd.exe, or
5082 command.com) to handle redirection metacharacters.
5084 - Allow the user to supply a command handler.
5088 - Search both /usr/lib and /usr/local/lib for scons directories by
5089 adding them both to sys.path, with whichever is in sys.prefix first.
5091 - Fix interpreting strings of multiple white-space separated file names
5092 as separate file names, allowing prefixes and suffixes to be appended
5093 to each individually.
5095 - Refactor to move CompositeBuilder initialization logic from the
5096 factory wrapper to the __init__() method, and allow a Builder to
5097 have both an action and a src_builder (or array of them).
5099 - Refactor BuilderBase.__call__() to separate Node creation/lookup
5100 from initialization of the Node's builder information.
5102 - Add a CFile Builder object that supports turning lex (.l) and
5103 yacc (.y) files into .c files.
5105 - Document: variable interpretation attributes; how to propogate
5106 the user's environment variables to executed commands; how to
5107 build variants in multiple BuildDirs.
5109 - Collect String, Dict, and List type-checking in common utility
5110 routines so we can accept User{String,Dict,List}s all over.
5112 - Put the Action factory and classes into their own module.
5114 - Use one CPlusPlusAction in the Object Builder's action dictionary,
5115 instead of letting it create multiple identical instances.
5117 - Document the Install() and InstallAs() methods.
5121 - Require that a Builder be given a name argument, supplying a
5122 useful error message when it isn't.
5126 - Add a "duplicate" keyword argument to BuildDir() that can be set
5127 to prevent linking/copying source files into build directories.
5129 - Add a "--debug=tree" option to print an ASCII dependency tree.
5131 - Fetch the location of the Microsoft Visual C++ compiler(s) from
5132 the Registry, instead of hard-coding the location.
5134 - Made Scanner objects take Nodes, not path names.
5136 - Have the C Scanner cache the #include file names instead of
5137 (re-)scanning the file each time it's called.
5139 - Created a separate class for parent "nodes" of file system roots,
5140 eliminating the need for separate is-parent-null checks everywhere.
5142 - Removed defined __hash__() and __cmp() methods from FS.Entry, in
5143 favor of Python's more efficient built-in identity comparisons.
5147 RELEASE 0.02 - Sun, 23 Dec 2001 19:05:09 -0600
5151 - Added the Install(), BuildDir(), and Export() methods.
5153 - Fix the -C option by delaying setting the top of the FS tree.
5155 - Avoid putting the directory path on the libraries in the LIBS
5156 construction variable.
5158 - Added a GetBuildPath() method to return the full path to the
5159 Node for a specified string.
5161 - Fixed variable substitution in CPPPATH and LIBPATH.
5165 - Fixed the version comment in the scons.bat (the UNIX geek used
5168 - Fix to setup.py so it doesn't require a sys.argv[1] argument.
5170 - Provide make-like warning message for "command not found" and
5173 - Added an EXAMPLES section to the man page.
5175 - Make Default() targets properly relative to their SConscript
5176 file's subdirectory.
5180 - Documented CXXFLAGS, CXXCOM, and CPPPATH.
5182 - Fixed SCONS_LIB_DIR to work as documented.
5184 - Made Default() accept Nodes as arguments.
5186 - Changed Export() to make it easier to use.
5188 - Added the Import() and Return() methods.
