[SciPy-User] numpy.distutils cross compile question

Dear all.

     I've written a small package in my field  containing  some pure 
python scripts and fortran extension libraries. At first I just use f2py 
for the compiling work before importing these extensions into python and 
they all worked well. This time, I write a "setup.py" file which import 
"setup" function in "numpy.distutils.core" and will build a scipy sub 
package on my ubuntu 64 machine, with gfortran specified by the command 
"python setup.py build fgnu95", which works well.

     My questions comes with the problem when I'd like to  build a win 
32/64 package. I think it concerns cross compiling, so I installed mingw 
compilers like "i686-w64-mingw32-gfortran" and "i686-w64-mingw-32-gcc" 
on my ubuntu 12.04. However I don't know how to write the setup.py file 
for cross compiling using numpy.distutils. I tried typing "python 
setup.py" and specify fortran compiler by typing 
"fi686-w64-mingw32-gfortran" for building, however it doesn't work. So 
I'm wondering whether I have to build this package on linux 32, 64 bit 
and win 32, 64 bit?

     Thanks a lot.
