distutils cygwin bdist_wininst

[Michiel Jan Laurens de Hoon]

I am trying to create a windows installer for my extension module using
distutils. Before, I have created the setup.py, and this works
beautifully on cygwin.

I would like to be able to distribute my extension as a Windows
installer, so that users don't have to mess around with compilers they
might not even have. If I try to make a windows installer on cygwin with

python setup.py bdist_wininst

I get the following error message:

....
distutils.errors.DistutilsPlatformError: distribution contains
extensions and/or C libraries; must be compiled on a Windows 32 platform

If I try to run the same command with Python under Windows instead of
Python on cygwin, then distutils tries to use the cl.exe compiler, which
I don't have.

Is it possible to create a Windows installer with distutils using the
Cygwin/mingw gcc compiler?

Thanks in advance.

$ python setup.py --compiler=mingw32
$ python setup.py bdist_wininst

'python' must be the win32 Python, *not* the Cygwin Python.

Thanks for your help. Unfortunately, if I try that, I get an error:

> c:\\python22\\python setup.py --compiler=mingw32
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help

error: option --compiler not recognized

I get the same error with both the win32 Python and the Cygwin Python.
My win32 Python is the latest version. Any idea what is going wrong? I
attached my setup.py in case it is of any help.

Thanks again -- Michiel

That should be

python setup.py build --compiler-mingw32

Thank you all for your help.

It almost works -- the source files get compiled and everything seems to
be fine, up to the linking stage where two references
(__imp___Py_NoneStruct and __imp__PyCObject_Type) are unresolved. These
two are (I think) in python22.lib, which gcc seems to find, but somehow
it can't find those two routines in it.

I also tried to link them as

c:\cygwin\usr\local\bin\gcc.exe -mno-cygwin -mdll -static --entry
_DllMain@12 -s

build\temp.win32-2.2\Release\cluster.def
c:\python22\libs\python22.lib -o
build\lib.win32-2.2\Pycluster\cluster.pyd -s

to make sure it finds python22.lib, but with the same result.
Any ideas? Sorry to bother you guys again.

I found the special trick needed to make this work. What I needed to do
was to add c:\winnt\system32\python22.dll explicitly to the list of
object files. I guess the -lpython22 is supposed to find python22.dll
instead of python22.lib, but the latter gets used because of the
-L c:\python22\libs.
My Windows installer works now.

Thanks again
