Apologies for troubling you all, the solution is quite simple. You just need to include library stdc++. I'll post something on the newsgroup. The setup.py file looks like: # setup.py - for building _pysimple.pyd # # To use, from command line type: # python setup.py build --compiler=mingw32 # # or python setup.py build --compiler=bcpp # # If sources=['pysimple.i'] then SWIG will be called # but do not yet know how to set SWIG options. # from distutils.core import setup, Extension setup (name = "_pysimple", version = "1.0", maintainer = "Andrew Gregory", maintainer_email = "andrew.gregory@npl.co.uk", description = "Sample Python DLL", ext_modules = [Extension('_pysimple', library_dirs=['C:\\mingw\\lib'], libraries=['stdc++'], sources=['pysimple_wrap.cxx'])]) Suggestion: a future release of distutils might do this automatically for mingw when the source extension is .cpp, .cc or .cxx?

Looks like some lib is missing. Hard to tell which without a working MinGW installed :-) That's not just "some lib", but a part of the C++ runtime. It may be as simple as setting LD_LIBRARY_PATH to include the location of the C++ runtimes shipped with mingw when linking.

Patches are welcome. AFAIK, nobody is supporting MinGW for distutils, so you're on your own here.

Could be that g++ needs to be used instead of gcc for compiling C++ code...

Yes, that is definitely the case.

...

at least that's what the CVS log suggests. The MinGW class has gcc hard-coded...

Easy fix, then!
