[f2py] Help with using f2py under WinXP

Dear ALL,

Greetings. I am new to py2f (and although not new to Python, I am not
used to writing extension modules). I have a very simple FORTRAN
module, consisting of two small subroutines, with which I want to
create a Python extension module under WindowsXP.

I have compiled and created the extension module with these
subroutines without any hassles under Ubuntu Linux (Jaunty), using g95
(v4.3.3-5), and they work as expected when called from a Python
program. However, when attempting to compile the extension under
WindowsXP (with Python 2.5 and Numpy 1.3, gfortran and gcc 4.6.0
(20100620) [trunk revision 161045] from MinGW), I have struck to a
number of errors.

To compile the extension module, I issued the command:

C:\Projetos\Croizat\source>python c:\Python25\scripts\f2py.py
--build-dir \tmp --fcompiler=gnu95 --compiler=mingw32 -lmsvcr71 -c
Calc.f -m Calc

I then get the following output:

--compiler options

running config_fc

As it can be seen from the two lines indicated by arrows, it seems
that the compiler is confused by the different styles of backlashes
("/" and "\"), but I have no idea of where to look for this!

I presume the subsequent errors are caused by this problem, however I
also could not locate the pyconfig.h under C:\Python25\include. The
output files "fortranobject.c", "fortranobject.h" and "Calcmodule.c"
are correctly created in the \tmp\scr.win32-2.5 directory, but it
seems that because it gets confused with the backlashes, the compiler
is not able to find them in order to complete the process of creating
the extension module.

Any hints?

Thanks in advance for any assistance you can provide.

With warmest regards,
