No need. Use Cython and Fortran 2003 ISO C bindings. That is the only portable way to interop between Fortran and C (including CPython) anyway.

Too add to Sturla - I think this is what he mentioned but in more details: http://www.fortran90.org/src/best-practices.html#interfacing-with-python Shawn On Tue, Jul 14, 2015 at 9:45 PM, Sturla Molden wrote:

For my wdmtoolbox I have a f2py wrapped Fortran 77 library. Works great on Linux, but because of the 'C' wrapper that f2py creates you run into the same problem as Cython on Windows. https://github.com/cython/cython/wiki/CythonExtensionsOnWindows I guess if you first find a Windows machine, get it all setup, you may not have to futz with it too much, but I just don't want to do it for such a niche package. I probably have a handful of users. So I've been toying with the idea to use ctypes + iso_c_binding. I could then use MinGW on Windows to compile the code for all versions of Python that have ctypes. I've tested this approach on a few functions and it works, but far from done. My $0.02. Kindest regards, Tim
