xmingw and f2py

[Flavio]

Hi Nick,

I followed the steps you describe exactly and I am still gettin this
error message when i try to compile.

here is the command I give:

f2py -c --compiler=/opt/xmingw/bin/i386-mingw32msvc-gcc
--f77exec=opt/xmingw/bi
n/i386-mingw32msvc-g77 -L /opt/xmingw/i386-mingw32msvc/lib/ -lpython2.4
-m flib flib.f

and this is the error:

copying
/usr/lib/python2.4/site-packages/numpy-1.0b5-py2.4-linux-i686.egg/numpy/f2py/src/fortranobject.c
-> /tmp/tmpIkxhAr/src.linux-i686-2.4

-> /tmp/tmpIkxhAr/src.linux-i686-2.4
  adding '/tmp/tmpIkxhAr/src.linux-i686-2.4/flib-f2pywrappers.f' to
sources.
running build_ext
error: don't know how to compile C/C++ code on platform 'posix' with
'/opt/xmingw/bin/i386-mingw32msvc-gcc' compiler

any further suggestions?
