Good afternoon!
I'm trying to build a Python module using F2PY on a simple Fortran
code using the PGI 17.4 community compilers.
I'm using Conda 4.3.21 with Python 2.7.13 and F2PY 2. The command
line I'm using is,
f2py --compiler=pg --fcompiler=pg -c -m mdevice mdevice.f90
The output from f2py is at the end of the email. Any suggestions
are greatly appreciated.
--compiler=pg seems wrong, that specifies the C/C++ compiler to use
not the Fortran compiler. Hence you get the error "don't know how to
compile C/C++ code on platform 'posix' with 'pg' compiler". Try just
leaving that off (thereby using the default C compiler you have
installed, probably gcc).
Ralf - thanks for the response! I had tried that before and F2PY still
thinks it's using the PGI C compiler:

I'm definitely at a lose here. I have no idea how to make F2PY work with
the PGI compilers. I'm beginning to think F2PY is completely borked
unless you use the defaults (gcc).
Thanks!

Thanks!
