[#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().
Two new tests are needed:
Don't skip building an extension if any of the depends files are newer
than the target.
Pass ext.depends to compiler.compile() so that it can track individual
files.
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.
present - at least the swigged file should be named <name>_wrap.c as
this is also SWIG's default. (Even better would be to generate the
wrapped sources in a different location, but I'll leave this for
later).
Newer versions of SWIG don't accept the -dnone flag any more.
Since virtually nobody uses SWIG with distutils, this should do no
harm.
Suggested be Martin Bless on c.l.p.
distutils for the library modules built as shared objects. A better solution
appears possible, but with the threat that the distutils becomes more
magical ("complex").
This closes SF bug #458343.
Lib/distutils/command/build_ext.py(build_ext.finalize_options): Add
Cygwin specific code to append Python's library directory to the
extension's list of library directories.
(build_ext.get_libraries): Add Cygwin specific code to append Python's
(import) library to the extension's list of libraries.
Removed get_ext_libname() because it is unused.
Fixed get_libraries() to append an '_d' to the python debug
import library. If MSVC is used, do not add 'pythonxx.lib' to
the list of libraries, because this is handled better
by a pragma in config.h.
This should fix bug #115595, but it needs some more testing.
- 'export_symbol_file' (and corresponding 'def_file' in the old
"build info" dict) are gone; warn if we see 'def_file' in the
dict
- the MSVC "pre-link hack" is gone -- all that stuff is now handled
elsewhere (eg. by using 'export_symbols', etc.)
- add 'get_export_symbols()' and 'get_libraries()' methods -- needed
because on Windows, both of those things are a tad more complicated
than fetching them from the Extension instance
to 'msvc_prelink_hack()', adding the parameters that it actually needs,
and only calling it for MSVC compiler objects. Generally gave up on the
idea of a general "hook" mechanism: deleted the empty 'precompile_hook()'.
in the module of the command classes that have command-specific
help options. This lets us keep the principle of lazily importing
the ccompiler module, and also gets away from defining non-methods
at class level.
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!
setup script) to be a list of Extension instances, rather than a list of of
(ext_name, build_info) tuples. This is mostly a simplification, but
'check_extension_list()' got a lot more complicated because of the need to
convert the old-style tuples to Extension instances.
Temporarily dropped support for defining/undefining macros in the
'extensions' list -- I want to change the interface, but haven't yet made
the required changes in CCompiler and friends to support this nicely.
Also neatened up the code that merges 'extra_compile_flags' and the CFLAGS
environment variable.
* Command method 'find_peer()' -> 'get_finalized_command()'
* Command method 'run_peer()' -> 'run_command()'
Also deleted the 'get_command_option()' method from Command, and
fixed the one place where it was used (in "bdist_dumb").
Also added creation of 'implib_dir', a temporary directory specific to
MSVC++ -- but I checked in two ways of fixing it (Lyle's and mine),
because I'm not sure which is right.
- DistutilsOptionError is now documented as it's actually used, ie.
to indicate bogus option values (usually user options, eg. from
the command-line)
- added DistutilsSetupError to indicate errors that definitely arise
in the setup script
- got rid of DistutilsValueError, and changed all usage of it to
either DistutilsSetupError or ValueError as appropriate
- simplified a bunch of option get/set methods in Command and
Distribution classes -- just pass on AttributeError most of
the time, rather than turning it into something else
* build to "Debug" or "Release" temp directory
* put linker turds (.lib and .exp files) in the build temp directory
* tack on "_d" to extensions built with debugging
* added 'get_ext_libname()' help in putting linker turds to temp dir
Also, moved the code that simplifies None to empty list for a bunch
of options to 'finalize_options()' instead of 'run()'.
Changed signature of 'build_extensions()': no longer takes the extension
list, but uses 'self.extensions' (just like 'get_outputs()' has to)
Moved call to 'check_extensions_list()' from 'run()' to 'build_extensions()',
again for consistency with 'get_outputs()'.
* replaced build_lib.py with build_clib.py
* renamed the class in build_clib.py
* changed all references to 'build_lib' command in other command classes
when building extensions (uses build_lib's 'get_library_names()' method).
Ensure that the relative structure of source filenames is preserved in
the temporary build tree, eg. foo/bar.c compiles to
build/temp.<plat>/foo/bar.o.
* 'build_dir' -> 'build_lib', which by default takes its value
straight from 'build_lib' in the 'build' command
* added 'build_temp' and 'inplace' options
* change 'build_extensions()' to put object files (compiler turds) in
'build_temp' dir
* complicated the name-of-extension-file shenanigans in
'build_extensions()' to support "in-place" extension building, i.e.
put the extension right into the source tree (handy for developers)
* added 'get_ext_fullname()', renamed 'extension_filename()' to
'get_ext_filename()', and tweaked the latter a bit -- all to support
the new filename shenanigans
'--help-commands' option).
Shuffled imports around in a few command modules to avoid expensive
up-front import of sysconfig (and resulting delays in generating list
of all commands).
Catch up with renamed 'platdir' -> 'build_platlib' option in 'build'.
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
If 'include_dirs' is a string, split it on os.pathsep (this is half-
hearted -- support for setting compile/link options on the command
line is totally lame and probably won't work at all).
Added 'get_source_files()' for use by 'dist' command.
Added code to 'build_extensions()' to figure out the "def file" to use
with MSVC++ and add it to the linker command line as an "extra_postarg".
- rename 'dir' to 'build_dir'
- take 'package' from distribution option 'ext_package'
- take 'extensions' from distribution option 'ext_modules'
- take 'include_dirs' from distribution
Name keyword args explictly when calling CCompiler methods.
Overhauled how we generate extension filenames (in 'extension_filename()
and 'build_extension()') to take 'package' option into account.
