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

[Manal Helal]

Thank you for your reply,

sorry for not trying that, I always link with mpicc, but it is  not working
under cygwin so far,

I tried gcc -lmpi, it seems working better but I think the 0 kb libmpi.a
problem is the one now,

here is the output:

**************************
/cygdrive/f/Program Files/MPICH2/lib/libmpi.a: file not recognized: File
truncat
ed
collect2: ld returned 1 exit status
**************************

I tried repairing the windows mpich2, but the file didn't change, and I
unisiatlled and removed the Program Files/MPICH2, and still the file size is
0 kb, and the same output when linking with gcc

please advise,

thank you very much,

Manal
