[Numpy-discussion] f2py "target file xxx not generated"

Hi,

I'm trying to get started with f2py on a Windows 7 environment using the
Python(x,y) v 2.6.5.6 distribution.
I'm following the introductory example of the f2py userguide and try to wrap
the file FIB1.F using the command:

f2py.py -c fib1.f -m fib1

from the windows command line. I get the following output:

output of f2py.py -c --help-fcompiler:

Running f2py without arguments result in the following version information:

Version:     1
numpy Version: 1.5.1
Requires:    Python 2.3 or higher.
License:     NumPy license (see LICENSE.txt in the NumPy source code)

I'm puzzled by this, I expect I have the compiler correctly installed, since
f2py recognizes it (and I am able to compile Fortran code using GCC from
Eclipse).
How about the f2py version number = 1? I was under the impression that
development had reached version >2.


Reinstalling Numpy from SourceForge numpy-1.5.1-win32-superpack-python2.6.exe
result in exactly the same output as above.

Trying to install f2py using easy_install and then running f2py without
arguments result in the following error:

Any comments on how to adapt my setup to allow f2py to function correctly
would be much appreciated!

Best regards,

Thomas
