Success at last !

I renamed the "mymodules" to "primes" in setup.py
*and* used the following line fromt he command line :
D:\Python Projects\c>setup.py build_ext --compiler=mingw32
running build_ext
building 'primes' extension
writing build\temp.win32-2.3\Release\primes.def
F:\MinGW\bin\gcc.exe -mno-cygwin -shared -s
build\temp.win32-2.3\Release\primes.
o build\temp.win32-2.3\Release\primes.def -LD:\Python23\libs
-LD:\Python23\PCBui
ld -lpython23 -o build\lib.win32-2.3\primes.pyd
D:\Python Projects\c>
I tried the command line option first and it failed - but I noticed the
presence of errors mentioning 'mymodules' -(which I assumed was just an
output name for the module) - so I renamed.... and it succeeded. I'll
try it again with disutils.
Hmm... just have - still get the Visual Studio 6 needed
error.................
So it looks like disutils *isn't* picking up my disutils.cfg.........
Oh well..........
Thanks for your help guys.
I look forward to trying some more interesting stuff over the weekend.
Regards,
Fuzzy

However - below are the resutls of my *failed* experiments last
night.............
I thought I'd followed the instructions in :
http://randomthoughts.vandorp.ca/syncato/WK/blog/758_Simple_instructions_to_compile_python_C_extensions_in_windows.item
to the letter !
(Thanks for the replies by the way - both Phillip and Greg).
Now the 'random thoughts' page says that after installing MinGW
successfully and adding a disutils.cfg file (which didn't exist
already).... I ought to be able to compile extensions from disutils
automagically.................
However it seems that maybe :
python setup.py build_ext --compiler=mingw32
is the right way instead.... (I'll try it when I get home)
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.
Can you tell me what the correct gcc incantion would be to generate a
.pyd I guestimated with the following result.:
D:\Python Projects\c>gcc -shared primes.o -L
D:\Python23\libs\libpython23.a -o
