This patch adds a new configure argument on OSX:
--with-universal-archs=[32-bit|64-bit|all]
When used with the --enable-universalsdk option this controls which
CPU architectures are includes in the framework. The default is 32-bit,
meaning i386 and ppc. The most useful alternative is 'all', which includes
all 4 CPU architectures supported by MacOS X (i386, ppc, x86_64 and ppc64).
This includes limited support for the Carbon bindings in 64-bit mode as well,
limited because (a) I haven't done extensive testing and (b) a large portion
of the Carbon API's aren't available in 64-bit mode anyway.
I've also duplicated a feature of Apple's build of python: setting the
environment variable 'ARCHFLAGS' controls the '-arch' flags used for building
extensions using distutils.
installed to build extensions. This patch makes distutils emit a warning when
the compiler should use an SDK but that SDK is not installed, hopefully reducing
some confusion.
This patchs makes it possible to create a universal build on OSX 10.4 and use
the result to build extensions on 10.3. It also makes it possible to override
the '-arch' and '-isysroot' compiler arguments for specific extensions.
On cygwin, the setup.py script uses unixccompiler.py for compiling and linking
C extensions. The unixccompiler.py script assumes that executables do not get
special extensions, which makes sense for Unix. However, on Cygwin,
executables get an .exe extension.
This causes a problem during the configuration step (python setup.py config),
in which some temporary executables may be generated. As unixccompiler.py does
not know about the .exe extension, distutils fails to clean up after itself: it
does not remove _configtest.exe but tries to remove _configtest instead.
The attached patch to unixccompiler.py sets the correct exe_extension for
cygwin by checking if sys.platform is 'cygwin'. With this patch, distutils
cleans up after itself correctly.

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().
Always use _setup_compile() to do the grunt work of processing
arguments, figuring out which files to compile, and emitting debug
messages for files that are up-to-date.
Use _get_cc_args() when possible.
Remove __init__ that just called base class __init__ with same args.
Fold long argument lists into fewer, shorter lines.
Remove parens in tuple unpacks.
Don't put multiple statements on one line with a semicolon.
In find_library_file() compute the library_filename() upfront.
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.
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()'.
meant playing along with the new "dictionary of executables" scheme
added to CCompiler by adding the 'executables' class attribute, and
changing all the compile/link/etc. methods to use the new attributes
(which encapsulate both the program to run and its standard arguments,
so it was a *little* bit more than just changing some names).
it in UnixCCompiler. Still needs to be implemented in MSVCCompiler (and
whatever other compiler classes are lurking out there, waiting to be
checked in).
than we actually use, and do actually use AR and SO.
Run ranlib on static libraries. (Should probably have a platform-check
so we don't run ranlib when it's not necessary, ie. on most modern
Unices.)
