This is the fourteenth alpha release of SCons. Please consult the
CHANGES.txt file for a list of specific changes since last release.
Please note the following important changes since release 0.13:
- - Tool specifications no longer take a "platform" argument.
- XXX
+ - Tool specifications no longer take a "platform" argument. You
+ will need to remove this argument if you define any local Tool
+ specifications. The new env['PLATFORM'] construction variable can
+ now be used to find the string that used to be passed in as the
+ "platform" argument.
- Emitter functions in Builders are now passed Node objects, not
strings, for all targets and sources. Your emitter may need to
now take a fourth "for_signature" argument that is set when the
expansion is being called to generate a build signature.
+ - Construction variables for building a target are now frozen when the
+ Builder is called; later changes to the Environment do not
+ necessarily affect how the target is build. You may need to
+ re-order statements in your SConscript files to make sure
+ construction variables are set before calling the Builders that will
+ use them.
+
Please note the following important changes since release 0.11:
- The default behavior of SCons is now to change to the directory in
- Modifying a construction environment in a subsidiary SConscript
file modifies the global environment.
- - PDB files on Win32 in a build that uses BuildDir() are built in
- the source directory, not the build directory.
-
- MSVC .res files are not rebuilt when icons change.
- The -c option does not clean up .sconsign files or directories
(for example) \some\target is the same as X:\some\target (for your
current volume X:).
+ - .sconsign files can be written even when the -n option is used,
+ possibly causing incorrect "up to date" builds the next time around.
+
+ - An explicit target beginning with "../" (i.e. above the current
+ directory) is ignored when using the -u, -U or -D options.
+
- No support yet for the following planned command-line options:
-d -e -l --list-actions --list-derived --list-where
