I will try and get this done on Monday.
Note that setting up a free win32 build environment using mingw is
not very difficult. Here are my notes for setting it up -- replace any
version numbers with the most recent
== Required setup ==
* Download MinGW-3.1.0-1.exe and MSYS-1.0.10.exe from
MinGW - Minimalist GNU for Windows - Browse /Other at SourceForge.net
and install both in C:\MinGW
* Download pexports-0.42h
from http://starship.python.net/crew/kernr/mingw32/pexports-0.42h.zip
and extract it to C:\Program Files\pexports-0.42h
For compiling C++ extensions under mingw, I found I needed to patch
c:/Python23/Lib/distutils/cygwinccompiler.py to work with g++. Find
the set_executables part and change it to
self.set_executables(compiler='gcc -mcygwin -O -Wall',
compiler_cxx='g++ -mcygwin -O -Wall',
compiler_so='gcc -mcygwin -mdll -O -Wall',
linker_exe='gcc -mcygwin',
linker_so=('%s -mcygwin %s' %
(self.linker_dll, shared_option)))
The compiler_cxx is where the change is.
For Python2.4 there is another oneline change you must make; see
os.walk bug?.
You must comment out
#self.dll_libraries = ['msvcr71']
== THE BUILD ==
Execute the following profile batch file to setup path and
environment variables
SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;c:\Python23;c:\mingw\bin;c:\mingw\mingw32\bin;c:\msys\1.0\bin
set LDD=gcc
set CC=gcc
set CXX=g++
set CFLAGS=-mms-bitfields
Execute the command below, changing the version numbers for other
pythons
copy c:\windows\system32\python24.dll .
c:\progra~1\pexports-0.42h\bin\pexports python24.dll > python24.def
c:\MinGW\bin\dlltool --dllname python24.dll --def python24.def --output-lib libpython24.a
copy libpython24.a c:\python24\libs
del python24.dll
del libpython24.a
Build the python binary installer for the package of your choice
python setup.py build --compiler=mingw32 bdist_wininst --install-script postinstall.py
