[mpich-discuss] need to compile unix code as windows exe

[Manal Helal]

Hello

I tried the following from the configure script, just to create the
references for the windows installation:

ln -s libmpich.a libmpi.a
ln -s libmpich.so.1 libmpi.so.1


I just also found that the windows mpich2 installation installed a 0 kb
libmpi.a in the "Program Files\MPICH2\lib" path?!

I think I am on the wrong direction all together, please help,

Kind Regards,

Manal
