callable() from copy_reg.py, so the interpreter now starts up
without warnings when '-3' is given. More work like this needs to
be done in the rest of the stdlib.
Use case: Sometimes 'compiling' source files (with SWIG, for example)
creates additionl files which included by later sources. The win32all
setup script requires this.
There is no SF item for this, but it was discussed on distutils-sig:
http://mail.python.org/pipermail/distutils-sig/2003-November/003514.html
specified with an absolute path, the object file is also
written to an absolute path. The patch drops the drive and
leading '/' from the source path, so a path like /path/to/foo.c
results in an object file like build/temp.i686linux/path/to/foo.o.
If you have source files srcdir1/foo.c and srcdir2/foo.c, the
temporary .o for both files is written to build/temp.<platform>/foo.o.
This patch sets strip_dir to false for both calls to object_filename,
so now the object files are written to temp.<platform>/srcdir1/foo.o
and .../srcdir2/foo.o.
2.2 bugfix candidate
[#413582] g++ must be called for c++ extensions
[#454030] distutils cannot link C++ code with GCC
topdir = "Lib/distutils"
* bcppcompiler.py
(BCPPCompiler.create_static_lib): Fixed prototype, removing extra_preargs
and extra_postargs parameters. Included target_lang parameter.
(BCPPCompiler.link): Included target_lang parameter.
* msvccompiler.py
(MSVCCompiler.create_static_lib): Fixed prototype, removing extra_preargs
and extra_postargs parameters. Included target_lang parameter.
(MSVCCompiler.link): Included target_lang parameter.
* ccompiler.py
(CCompiler): New language_map and language_order attributes, used by
CCompiler.detect_language().
(CCompiler.detect_language): New method, will return the language of
a given source, or list of sources. Individual source language is
detected using the language_map dict. When mixed sources are used,
language_order will stablish the language precedence.
(CCompiler.create_static_lib, CCompiler.link, CCompiler.link_executable,
CCompiler.link_shared_object, CCompiler.link_shared_lib):
Inlcuded target_lang parameter.
* cygwinccompiler.py
(CygwinCCompiler.link): Included target_lang parameter.
* emxccompiler.py
(EMXCCompiler.link): Included target_lang parameter.
* mwerkscompiler.py
(MWerksCompiler.link): Included target_lang parameter.
* extension.py
(Extension.__init__): New 'language' parameter/attribute, initialized
to None by default. If provided will overlap the automatic detection
made by CCompiler.detect_language(), in build_ext command.
* sysconfig.py
(customize_compiler): Check Makefile for CXX option, and also the
environment variable CXX. Use the resulting value in the 'compiler_cxx'
parameter of compiler.set_executables().
* unixccompiler.py
(UnixCCompiler): Included 'compiler_cxx' in executables dict, defaulting
to 'cc'.
(UnixCCompiler.create_static_lib): Included target_lang parameter.
(UnixCCompiler.link): Included target_lang parameter, and made
linker command use compiler_cxx, if target_lang is 'c++'.
* command/build_ext.py
(build_ext.build_extension): Pass new ext.language attribute
to compiler.link_shared_object()'s target_lang parameter. If
ext.language is not provided, detect language using
compiler.detect_language(sources) instead.
* command/config.py
(config._link): Pass already available lang parameter as target_lang
parameter of compiler.link_executable().
Strangely, two out of three patches there seem already committed; but
the essential one (get rid of the assert in object_filenames in
ccompiler.py) was not yet applied.
This makes the build procedure for Twisted work again.
This is *not* a backport candidate despite the fact that identical
code appears to exist in 2.2.2; Twisted builds fine there, so there
must have been a change elsewhere.
The default implementation calls _compile() to compile individual
files. This method must be implemented by the subclass. This change
factors out most of the remaining common code in all the compilers
except mwerks.
This change is not backwards compatible. If a compiler subclass
exists outside the distutils package, it may get called with the
unexpected keyword arg. It's easy to extend that compiler by having
it ignore the argument, and not much harder to do the right thing. If
this ends up being burdensome, we can change it before 2.3 final to
work harder at compatibility.
Also add _setup_compile() and _get_cc_args() helper functions that
factor out much of the boilerplate for each concrete compiler class.
This is a conservative version of SF patch 504889. It uses the log
module instead of calling print in various places, and it ignores the
verbose argument passed to many functions and set as an attribute on
some objects. Instead, it uses the verbosity set on the logger via
the command line.
The log module is now preferred over announce() and warn() methods
that exist only for backwards compatibility.
XXX This checkin changes a lot of modules that have no test suite and
aren't exercised by the Python build process. It will need
substantial testing.
the Cygwin-specific compiler class.
(According to Jason Tishler, cygwinccompiler needs some work to
handle the differences in Cygwin- and MSVC-Python. Makefile and
config files are currently ignored by cygwinccompiler, as it was
written to support cygwin for extensions which are intended to be
used with the standard MSVC built Python.)
and also takes the sys.platform name into account. This helps on
platforms where there are multiple possible compiler backends (the
one with which Python itself was compiled is preferred over others
in this case).
The patch uses this new technique to enable using cygwin compiler
per default for cygwin compiled Pythons.

implementations. Details:
* replace 'link_shared_object()', 'link_shared_lib()', and
'link_executable()' with 'link()', which is (roughly)
the union of the three methods it replaces
* in all implementation classes (UnixCCompiler, MSVCCompiler, etc.),
ditch the old 'link_*()' methods and replace them with 'link()'
* in the abstract base class (CCompiler), add the old 'link_*()'
methods as wrappers around the new 'link()' (they also print
a warning of the deprecated interface)
Also increases consistency between MSVCCompiler and BCPPCompiler,
hopefully to make it easier to factor out the mythical WindowsCCompiler
class. Details:
* use 'self.linker' instead of 'self.link'
* add ability to compile resource files to BCPPCompiler
* added (redundant?) 'object_filename()' method to BCPPCompiler
* only generate a .def file if 'export_symbols' defined
methods (but not 'link_executable()', hmmm). Currently only used by
BCPPCompiler; it's a dummy parameter for UnixCCompiler and MSVCCompiler.
Also added 'bcpp' to compiler table used by 'new_compiler()'.
that a particular compiler system depends on. This consists of the
'set_executables()' and 'set_executable()' methods, and a few lines in
the constructor that expect implementation classes to provide an
'executables' attribute, which we use to initialize several instance
attributes. The default implementation is somewhat biased in favour of
a Unix/DOS "command-line" view of the world, but it shouldn't be too
hard to override this for operating systems with a more sophisticated
way of representing programs-to-execute.
it in UnixCCompiler. Still needs to be implemented in MSVCCompiler (and
whatever other compiler classes are lurking out there, waiting to be
checked in).
values that "--foo" can take for various commands: eg. what formats for
"sdist" and "bdist", what compilers for "build_ext" and "build_clib".
I have *not* reviewed this patch; I'm checking it in as-is because it also
fixes a paper-bag-over-head bug in bdist.py, and because I won't have
time to review it properly for several days: so someone else can
test it for me, instead!
Split '_fix_link_args()' up into '_fix_object_args()' (for use of
'create_static_lib() and link methods) and '_fix_lib_args()' (for the
link methods only).
option in the 'build_ext' command):
* in ccompiler.py: 'gen_lib_options()' now takes 'runtime_library_dirs'
parameter
* in unixccompiler.py and msvccompiler.py: now pass
'self.runtime_library_dirs' to 'gen_lib_options()', and define
'runtime_library_dir_option()' (although in msvccompiler.py it
blows up with a DistutilsPlatformError right now!)
