To follow up on my own post, I've noticed that Python distutils under Cygwin does not link to /usr/bin/libpython2.1.dll, but rather to -L/usr/lib/python2.1/config -lpython2.1, which is a different library. Anyway, when I try this new approach, the linking stage fails due to extra leading underscores in object files. Since this is the same problem as in http://www.cygwin.com/ml/cygwin/2001-07/msg01699.html , I'll append what I've done and my problems to that thread. >Hi, > >I'm trying to build a simple C++ Python extension module under the latest >cygwin. > >The module's name is 'convert'.
