I'm attempting to build an interface between a Fortran application I
have and Python. The problem I'm having is that f2py is not recognizing
my Absoft Fortran compiler. Details follow.
I'm running on a iMacPro (2017) under Mac OS X Mojave (ver. 10.14.4).
The version of the Absoft Compiler I'm running is 19.0.0. I'm using the
Anaconda distribution of Python 3, version 3.6.8, where the version of
NumPy used is ver. 1.16.3.
The commands I'm using to build the Python interface function and there
results are:
f2py -m DIVA_EphGen_f77 -h DIVA_EphGen_f77.pyf DIVA_EphGen_f77.f

A copy of the Fortran code and its corresponding .pyf file have been
attached to this note.
Any suggestions as to how to fix this problem.
