It's better to ask these questions on numpy-discussion, instead. There are more f2py users per capita there. http://www.scipy.org/Mailing_Lists > I am able to create a <module_name>.so file fine; > however, when I import it into Python, I receive the following > message: > >>>> import matsolve2 > Traceback (most recent call last): > File "<stdin>", line 1, in ? > ImportError: ./matsolve2.so: undefined symbol: _gfortran_filename > > > The steps I used to create the matsolve2.so file are as follows: > > (1) Created a Fortran90 program matsolve.f90 > > Note: The program compiles fine and prints the proper output for the > simple matrix specified.

You want to specify the *kind* of Fortran compiler such that f2py knows what compile/link flags to use. Only use the --f90exec option to inform f2py that the actual executable is named something odd or is in an unexpected place, like /opt/gfortran/bin/gfortran-4.3, for example. The correct option to use is --fcompiler=gnu95 -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
