[Numpy-discussion] Help for Windows Python, numpy and f2py (original) (raw)

Good morning, I used the Windows installer to install Python 2.4.3 on a late-model Dell PC running XP Pro. Then I installed numpy-0.9.8 and scipy-0.4.9, also from the Windows installers. Now I am trying to build a dll file for a Fortran 77 file and previously-generated (Linux) pyf file. I installed MinGW from the MinGW 5.0.2 Windows installer, and modified my Windows path to put the MinGW directory before a pre-existing Cygwin installation. However, both a setup.py file and running the C:\python2.4.3\Scripts\f2py.py file in the Windows command line fail with the message that the .NET Framework SDK has to be initialized or that the msvccompiler cannot be found. Any advice on what I'm missing would be much appreciated! Here is the message I get trying to run f2py:

C:\projects\workspace\MARSFortran>C:\python2.4.3\python C:\python2.4.3\Scripts\f 2py.py -c --fcompiler=g77 mars.pyf mars.f>errors error: The .NET Framework SDK needs to be installed before building extensions f or Python.
