Where did you put the distutils.cfg?  It has to go in your 
Python2X\Lib\distutils directory.  Mine looks like this:

[build]
compiler=mingw32

If you have that in place, you should never need the --compiler flag.  In 
the two years I've had that file, I've never needed --compiler or -c.

Second, did you actually build a 'libpython2x.a' file?  You didn't mention 
that.  If you didn't do that, you're not going to be able to actually build 
a .pyd.  See step 2 on this page:

http://sebsauvage.net/python/mingw.html


(By the way, whenever I refer to "python2x" I mean e.g. python22 or 
python23, as appropriate for what version you're using.)


>F:\Python Projects\c>gcc -shared primes.o -o primes.so

That won't work.  Windows uses '.pyd' files, not '.so' files.  And, you've 
got no -L here to specify where your libpython is at.
