[f2py] Specific problems in using f2py on Windows for newbie

[Jarrod Wilcox]

Pearu et al

Thank you for response to previous post.  My query now has more detail.

I am running on Intel Core 2 64 bit Windows 7.  I reinstalled Python and
numpy using the Enthought free distribution, with Python 2.7.2 (32 bit) July
3, 2011.

To get C and Fortran compilers, I also installed MinGW using the prepackaged
executable version 0.3-alpha-2.1.  It includes MSYS, although I did not use
it in what follows.

As a newbie, I am most comfortable running from IDLE rather than a terminal
window.  An IDLE script follows:
----------------------------------------------------------------------------
-------------
import numpy
from numpy import f2py
import sys

print("sys.path:")
print(sys.path)

def main():
    print("Entering main()")
    if '-c' in sys.argv[1:]:
        f2py.f2py2e.run_compile()
    else:
        f2py.f2py2e.run_main(sys.argv[1:])
        
print("RESULT OF: f2py -m fib1 -h fib1.pyf C:/pydev/data/fib1.f --build-dir
C:/pydev/data/temp/")
fcommand="f2py -m fib1 -h fib1.pyf C:/pydev/data/fib1.f --build-dir
C:/pydev/data/temp/"
sys.argv=fcommand.split()
answer1=main()
print(answer1)

print(' ')
print("RESULT OF: f2py -c --help-fcompiler")   
fcommand="f2py -c --help-fcompiler"   
sys.argv=fcommand.split()
answer2=main()
print(answer2)

print(' ')
print("RESULT OF: f2py -c c:/pydev/data/temp/fib1.pyf c:/pydev/data/fib1.f")
fcommand="f2py -c c:/pydev/data/temp/fib1.pyf c:/pydev/data/fib1.f"    
sys.argv=fcommand.split()
answer3=main()
print(answer3)

ADVICE, PLEASE ASSUME I HAVE ONLY VERY SLIGHT FAMILIARITY WITH C AND UNIX.
