3 SCons checkpoint release 1.2.0.d20090223 is now available at the SCons
6 http://www.scons.org/download.php
8 This checkpoint provides early access to new features and fixes
9 scheduled for release in SCons 1.3.0.
14 - This checkpoint release notably contains completely new code for
15 detecting installed versions of Microsoft Visual C/C++. The new code
16 has been tested extensively, but it is possible that it will fail to
17 find installed versions on configurations that we don't have available
18 for testing. Please report *any* problems with support for Microsoft
19 Visual C/C++ as soon as possible so that we can diagnose and fix
20 them before releasing SCons 1.3.0.
22 - Python versions prior to 2.4 are supported by SCons 1.2.0, but are
23 officially deprecated and will generate a disableable warning message.
24 We plan to remove support for these older versions in SCons 2.0.
25 If removing this support would cause a problem for you, please contact
26 the dev@scons.tigris.org mailing list.
28 - The following deprecated features will still be supported in 1.3.0
29 but will generate mandatory, non-disableable warnings:
31 -- Support for Python versions 1.5, 1.6, 2.0, 2.1, 2.2, and 2.3.
32 -- The overrides= keyword argument to the Builder() call.
33 -- The scanner= keyword argument to the Builder() call.
34 -- The BuildDir() function and env.BuildDir() method.
35 -- The env.Copy() method.
36 -- The SourceSignatures() function and
37 env.SourceSignatures() method.
38 -- The TargetSignatures() function and
39 env.TargetSignatures() method.
40 -- The Sig module (now an unnused stub).
41 -- The --debug=dtree, --debug=stree and --debug=tree options.
42 -- The --debug=nomemoizer option.
43 -- The Options object and the related BoolOption(), EnumOption(),
44 ListOption(), PackageOption() and PathOption() functions.

54 For a complete list of changes in all releases, see the official
57 http://www.scons.org/CHANGES.txt
59 We do not recommend that downstream distributions (Debian, Fedora,
60 etc.) package a checkpoint release, mainly to avoid confusing the
61 "public" release numbering with the long checkpoint release names.
64 Here is a summary of all changes since the 1.1.0 release:
69 - SCons now supports batch compilation of Visual Studio C/C++ source
70 files when the new $MSVC_BATCH construction variable is set.
71 - New reserved $CHANGED_SOURCES, $CHANGED_TARGETS, $UNCHANGED_SOURCES
72 and $UNCHANGED_TARGETS variables provide finer-grained control
73 over what source or targets to pass to a command line.
74 - A new batch_key= keyword argument to Action object creation supports
75 general batched builds.
76 - A new --warn=future-deprecated option provides advance warnings about
77 future deprecated features that still have warnings hidden by default.
78 - Visual Studio 8 project files can now be generated for 64-bit platforms.
79 - Visual Studio & Visual C++ now support TARGET_OS, TARGET_ARCH for
80 cross-compiling to x86, x86_64, ia64
82 CHANGED/ENHANCED EXISTING FUNCTIONALITY
84 - $CCFLAGS is no longer included in the default definitions of $CXXFLAGS
85 for Visual C/C++ and MIPSpro C++ on SGI (to match other tools and
86 avoid flag duplication on C++ command lines).
87 - The $CCFLAGS variable is now passed to Visual C/C++ precompiled header
89 - Scanning files encoded in utf-8 and utf-16 for implicit dependencies
91 - Linker tools modules now differentiate properly between the SharedLibrary
92 and LoadableModule Builders.
93 - Don't automatically try to build .pdf graphics files for .eps files in
94 \includegraphics{} calls in TeX/LaTeX files when building with the PDF
95 builder (and thus using pdflatex).
96 - Setting WINDOWS_INSERT_DEF=0 now disables --output-def when linking
98 - AppendENVPath() and PrependENVPath() now interpret '#' in paths
99 relative to the top-level SConstruct directory.
100 - The message, "scons: Build interrupted." is no printed on error output,
102 - Quoted module names in SWIG source files are no handled correctly.
103 - Suffix-matching for scanners is now case-insensitive on Windows.
104 - Generated Visual Studio 8 project files now work better with
105 IntelliSense, by defining IncludeSearchPath and PreprocessorDefinitions.
106 - Unnecessary nested $( $) strings around $_LIBDIRFLAGS have been removed
107 from the default command lines for the Microsoft linker, the OS/2
108 ilink linker and the Phar Lap linkloc linker.
109 - SCons now internally spells the Windows environment variables
110 "SystemDrive" and "SystemRoot" (instead of "SYSTEMDRIVE" and
112 - Major revamp of Visual Studio/Visual C++ logic for locating and
113 configuring available version on the machine.
117 - The $CHANGED_SOURCES variable now correctly includes files whose
118 corresponding targets don't exist.
119 - The $CHANGED_SOURCES variable now works correctly with the
120 --config=force option.
121 - $SOURCE and $SOURCES attributes now work even when there are no
122 sources specified in the Builder call.
123 - $SWIGOUTDIR values with spaces now work properly.
124 - Fix use of $SWIGOUTDIR when generating Python wrappers.
125 - Add $SWIGDIRECTORSUFFIX and $SWIGVERSION construction variables.
126 - The Borland ilink linker now uses the -e option to specify the output
128 - SCons now correctly identifies shared libraries and shared object files
130 - Implicit command dependencies are detected even when the first argument
131 is quoted on the command line.
132 - #include file names that contain escaped backslashes (\\) are now
134 - Have AddOption() remove variables from the list of
135 seen-but-unknown variables (which are reported later).
136 - An option name and aliases can now be specified as a tuple.
138 - Fix the -n option when used with VariantDir(duplicate=1)
139 and the variant directory doesn't already exist.
140 - Fix scanning of Unicode files for both UTF-16 endian flavors.
141 - Fix a TypeError on #include of file names with Unicode characters.
142 - Fix an exception if a null command-line argument is passed in.

144 (sources and dependencies).
145 - Remove redundant __metaclass__ initializations in Environment.py.
146 - Fix SWIG testing infrastructure to work on Mac OS X.
148 - When reporting a target that SCons doesn't know how to make,
149 specify whether it's a File, Dir, etc.
150 - Add -recorder flag to Latex commands and updated internals to
151 use the output to find files TeX creates. This allows the MiKTeX
152 installations to find the created files

155 - Remove LATEXSUFFIXES from environments that don't initialize Tex.
156 - Add support for the glosaaries package for glossaries and acronyms

162 the name of the output file from the latex default
169 - The TestCommon.shobj_prefix variable is now documented.
170 - Document that the msvc Tool module uses $PCH, $PCHSTOP and $PDB.
