Hi, I've been using f2py to generate an extension module for someone's free-form f90 code. I need to pass extra arguments to config_fc and right now to get everything working I do this: python setup.py config_fc --f90flags='-ffree-form -fno-underscoring' build_ext --inplace Is there an easy way to set the --f90flags set by default to what I want in the setup.py script itself? I.e. I'd like users to be able to do: python setup.py build_ext --inplace This doesn't seem documented anywhere, is there some place I should look? This is how my setup.py looks currently: #---- from numpy.distutils.core import Extension, setup setup(ext_modules = [Extension("varsha", ["varsha.pyf", "s2p.f", "fft.c", "invLeg.c"], define_macros=[('NO_APPEND_FORTRAN', None)], ) ], ) #---- passing config_fc={...} to either Extension or setup does not work. The numpy version is 1.4.0.dev6976. Thanks! cheers, prabhu
