Thanks a lot for providing the example Sturla, that is exactly what we are
looking for!

Something along the lines as:


Take a look at what SciPy does.

https://github.com/scipy/scipy/blob/81c096001974f0b5efe29ec83b54f725cc681540/scipy/fftpack/setup.py

Multiple Fortran files are compiled into a static library using 
"add_library", which is subsequently linked to the extension module.

[Numpy-discussion] f2py, numpy.distutils and multiple Fortran source files

[David Verelst]

Hi,

For the wafo [1] package we are trying to include the extension compilation
process in setup.py [2] by using setuptools and numpy.distutils [3]. Some
of the extensions have one Fortran interface source file, but it depends on
several other Fortran sources (modules). The manual compilation process
would go as follows:

gfortran -fPIC -c source_01.f
gfortran -fPIC -c source_02.f
f2py -m module_name -c source_01.o source_02.o source_interface.f

Can this workflow be incorporated into setuptools/numpy.distutils?
Something along the lines as:

from numpy.distutils.core import setup, Extension
ext = Extension('module.name',
   depends=['source_01.f', 'source_02.f'],
   sources=['source_interface.f'])

(note that the above does not work)

David

This might be helpful:
https://github.com/timcera/wdmtoolbox/blob/master/setup.py

Looks like I created the *.pyf file and include that in sources.  I think I
only used f2py to create the pyf file and not directly part of the
compilation process.  If memory serves the Extension function knows what to
do with the pyf file.

Kindest regards,
Tim
