Note that --fcompiler= and other such options are actually options
to numpy.distutils (f2py script would just pass these options
forward to numpy.distutils). f2py_options can contain only f2py
specific options.
Hence you should try to modify sys.path
in the beggining of the setup.py file to specify the fortran
compiler options. For example, in setup.py file, insert:
import sys
sys.path.extend('config_fc --fcompiler=intel ....'.split())
See
python setup.py config_fc --help
python setup.py build_ext --help
for more information about possible options.
