F2py and Compaq Visual Fortran 6.6, Win-XP

[Markus Faust]

Hi,

I'm trying to link Fortran files generated with “Compaq Visual Fortran
Optimizing Compiler Version 6.6 (Update B)” under “Enthought Edition
build 1028, Python 2.3 (#46, Aug 11 2003, 09:34:05) [MSC v.1200 32 bit
(Intel)] on win32” on Windows-XP”.

I changed mingw32_support.py as proposed by Pearu Peterson on April 8
2003 (I changed `if 1:` block into `if 0:` block).

When trying the following Python session:
import sys
from scipy_distutils.command.build_flib import
compaq_visual_fortran_compiler
class wrap(compaq_visual_fortran_compiler):
def announce(self, s):
sys.stdout.write(s+'\n')
wrap().get_version()

I get

Has anybody an idea what could be wrong? Finally I would like to link
f90 files to Python.

Hooks related to find_exe were changed in Python 2.3 distutils and this
causes the import error above in your scipy_distutils that assumes Python
2.2 or earlier. CVS version of scipy_distutils works now also with Python
2.3. So, you should update scipy_distutils from scipy CVS when you are
planning to use Python 2.3.

This looks much better now, but I do not succeed in invoking the Visual
Fortran Compiler. f2py always calls the mingw compiler. Do you have an
idea? Thanks in advance Markus!

This is because f2py finds mingw compiler first. You can force f2py
to use other compilers either by defining

FC_VENDOR=Compaq

environment variable or using

--fcompiler=Compaq

switch. Note that the latter does not work with f2py.bat script on windows
and as a workaround write a f2py.py script containing two lines

import f2py2e
f2py2e.main()

In fact, I am dropping f2py.bat support for future f2py releases
(because I don't how to prevent .bat script to replace `=` with ` `). So,
you can remove f2py.bat altogether from your system.

Pearu
