Python: undefined reference to `_imp __Py_InitModule4'

Question

I'm trying to do a debug build of the Rabbyt library using mingw's gcc to run with my MSVC built python26_d.. I got a lot of undefined references which caused me to create libpython26_d.a, however one of the undefined references remains. Googling gives me:

But -rdynamic doesn't help.

Answer 1

My Cygwin and MinGW gcc installs were conflicting with each other. I deleted them both and the installed MinGW and cygwin without gcc and that solved the problem.

Answer 2

I got exactly the same problem here. I'm operating under Win7, trying to build an extension (written in C or C++) to python. After creating libpython26.a with "pexports" and "dlltool" most of the "undefined reference" errors are gone - but one: undefined reference to `imp_Py_InitModule4'. I did not install cygwin at all - only Python26 and MinGW.
