"""distutils.cygwinccompiler
Provides the CygwinCCompiler class, a subclass of UnixCCompiler that
handles the Cygwin port of the GNU C compiler to Windows. It also contains
the Mingw32CCompiler class which handles the mingw32 port of GCC (same as
cygwin in no-cygwin mode).
"""
# problems:
#
# * if you use a msvc compiled python version (1.5.2)
# 1. you have to insert a __GNUC__ section in its config.h
# 2. you have to generate a import library for its dll
# - create a def-file for python??.dll
# - create a import library using
# dlltool --dllname python15.dll --def python15.def \
# --output-lib libpython15.a
#
# see also http://starship.python.net/crew/kernr/mingw32/Notes.html
#
2001-12-06 16:51:35 -04:00
# * We put export_symbols in a def-file, and don't use
# --export-all-symbols because it doesn't worked reliable in some
# tested configurations. And because other windows compilers also
# need their symbols specified this no serious problem.
#
# tested configurations:
2001-12-06 16:51:35 -04:00
#
# * cygwin gcc 2.91.57/ld 2.9.4/dllwrap 0.2.4 works
# (after patching python's config.h and for C++ some other include files)
# see also http://starship.python.net/crew/kernr/mingw32/Notes.html
2001-12-06 16:51:35 -04:00
# * mingw32 gcc 2.95.2/ld 2.9.4/dllwrap 0.2.4 works
# (ld doesn't support -shared, so we use dllwrap)
# * cygwin gcc 2.95.2/ld 2.10.90/dllwrap 2.10.90 works now
# - its dllwrap doesn't work, there is a bug in binutils 2.10.90
2000-08-31 22:24:31 -03:00
# see also http://sources.redhat.com/ml/cygwin/2000-06/msg01274.html
# - using gcc -mdll instead dllwrap doesn't work without -static because
# it tries to link against dlls instead their import libraries. (If
# it finds the dll first.)
# By specifying -static we force ld to link against the import libraries,
# this is windows standard and there are normally not the necessary symbols
# in the dlls.
2001-12-06 16:51:35 -04:00
# *** only the version of June 2000 shows these problems
# * cygwin gcc 3.2/ld 2.13.90 works
# (ld supports -shared)
# * mingw gcc 3.2/ld 2.13 works
# (ld supports -shared)

I've also fixed build_ext to support PCbuild8 and PCbuild9 and backported my fix for xxmodule.c from py3k. The old code msvccompiler is still in place in case somebody likes to build an extension with VS 2003 or earlier. I've also updated the cygwin compiler module for VS 2005 and VS 2008. It works with VS 2005 but I'm unable to test it with VS 2008.
