building C modules in windows + Python 2.3 + cygwin

[Andreou Giannis]

Allthough it is possible to build modules in Python2.3.3 and distutils
with cygwin,
by running:
setup.py build --compiler=cygwin
(after i created the libpython23.a)
running:
setup.py install
afterwards, complains about not building with msvs v.6,
since my Python distribution is built with it.

Since previous Python releases for windows allowed install of modules
that were built with different compilers then that of the current
distribution, with was this feature removed from distutils in Python
version 2.3?


Is there a workaround for this problem?
Can i simply copy the module file in the proper directory?
I do not want to install VS ver.6.

Thank you.

Andreou,

Allthough it is possible to build modules in Python2.3.3 and distutils
with cygwin, by running:
setup.py build --compiler=cygwin

AFAICT, you should use --compiler=mingw32, if you want to create a
native Win32 Python extension:

$ python setup.py --dry-run build --compiler=mingw32
running build
running build_ext
building 'readline' extension
C:\Cygwin\bin\gcc.exe -mno-cygwin ...
^^^^^^^^^^^

Using --compiler=cygwin, I get the following:

$ python setup.py --dry-run build --compiler=cygwin
running build
running build_ext
building 'readline' extension
C:\Cygwin\bin\gcc.exe -mcygwin ...
^^^^^^^^

which should produce a Cygwin Python extension.

Is there a workaround for this problem?

I don't know.

Can i simply copy the module file in the proper directory?

Yes. FWIW, this is how I install the Win32 Python readline module
every time I upgrade my Win32 Python installation...

python setup.py install --skip-build

Note that --skip-build should work in other places where it currently
doesn't/is ignored (bdist comes to mind, any workarounds for it except
bdist_wininst, which oddly works?)

If it's a simple package, there shoulnd't be any problem with this.

Thomas Heller pointed out here some time back how to reorder the
arguments to work around this.

I'm too tired to remember how exactly...
