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

Found a solution myself:

I tried to compile the fib1.f file directly using the gfortran compiler, and
found that indentation in the (fixed format) file was wrong. Correcting this
took care of the "target file xxx not generated" error, but still an error
resulted:

...
...
error: Unable to find vcvarsall.bat


A bit of googling pointed me to the following thread:
http://code.google.com/p/rdflib/issues/detail?id=104#c4
which suggests creating a "distutils.cfg" file.

After creating this file as described in the above reference, everything
wraps/compiles smoothly, and the fib1 subroutine is callable from Python.

Best regards,

Thomas
