Robert, Thanks for your prompt response. I think I got a lot closer but no cigar yet.
This is the output C:\fortrandll>f2py -c -m sample sample.pyf sample.for numpy_info: FOUND: define_macros = [('NUMERIC_VERSION', '"\\"24.2\\""')] include_dirs = ['C:\\Python24\\include'] running build running config_fc running build_src building extension "sample" sources creating c:\docume~1\fb\locals~1\temp\tmpcosvgv creating c:\docume~1\fb\locals~1\temp\tmpcosvgv\src f2py: sample.pyf Reading fortran codes...

I think I have a problem with distutils' msvccompiler.py. It may be the MacroExpander in distutils guessing the visual studio path incorrectly or something related to the registry keys. Is there a way to specify the C compiler path to f2py so that it does not rely on the distutils? Or maybe I am totally off base here, I don't know. Any thoughts? -- http://mail.python.org/mailman/listinfo/python-list
