Compiling extensions

[Andrea Gavana]

Hello NG,

I'm struggling and googling around, but without big success. I am
trying to build a fortran extension with F2PY, and it seems to me an
impossible task. At the moment, I have the following installed:

- Latest f2py
- MS Visual Studio 2003
- Python 2.4
- Intel Visual Fortan 9.1

I keep getting errors on undefined symbols/repeated symbols, like:

Well, I would like to ask: is there *any* possible combination of
C/Fortran compilers that actually *works* with Python2.4 on WIndows
XP? Does anyone have some suggestion?

Thank you very much.

Andrea.
