Normally, one uses the following procedure to build
and install a C/C++
extension:
python setup.py build --compiler=your_c ompiler
python setup.py install
For Python 2.3.3 on Windows, with the Mingw
(Minimalist GNU) compiler,
the following steps must be taken:
1. Find your Mingw bin directory. Copy gcc.exe to
cc.exe.
2. Get PExports from either of:
http://sebsauvage.net/python/pexports-0.42h.zip http://starship.python.net/crew/kern...orts-0.42h.zip
Extract pexports.exe to your Mingw bin directory.
3. Find pythonxx.dll. It should be in your main
Python directory. Do
the following:
pexports python23.dll > python23.def
dlltool --dllname python23.dll --def python23.def
--output-lib libpython23.a
4. Copy libpythonxx.a to \python\libs.
5. Patch distutils. Locate
\python\lib\dis tutils\msvccomp iler.py, open
it, and find the following lines (around line 211):
if len (self.__paths) == 0:
raise DistutilsPlatfo rmError, \
("Python was built with version %s
of Visual Studio, "
"and extensions need to be built
with the same "
"version of the compiler, but it
isn't installed." % self.__version)
Delete these.
6. Move back to the directory of your extension. Do
the following:
python setup.py build --compiler=mingw3 2
python setup.py install
Ideally, only step 6 should be required to install an
extension.
I submitted the patch for step 5 to
python.sourcefo rge.net.
Steps 2-4 can be avoided if the libpythonxx.a file is
distributed
with Python. I'll email the Python folks and ask
them to do this.
Step 1 can probably be avoided with another patch.
This document is based on
http://sebsauvage.net/python/mingw.html,
which was written for Mingw + Python 2.2.

To test this process, try compiling myspell-python, a
spell checking library for Python. See
