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

[Manal Helal]

Hello

sorry for the late reply.

I removed MPICH2 on windows XP, and resinatlled the
"mpich2-1.0.8-win-ia32.msi" downloaded on the 19th of November. I
don't have now the libraries as zero kb as before. Now I can link
-lmpi and it works and not lmpich like before.

However, in the sample program it is linking and generating the exe
file, and in the main project, it is only in another folder, and it is
complaining about all mpi calls : beginning from

/home/user/project/main.c:314: undefined reference to `_MPI_Init'

down to:


/home/user/project/main.c:366: undefined reference to `_MPI_Finalize'


again for the hello.exe test program generated, I can not run as
before, and the "mpiexec -validate" fails, and I don't know how to fix
that, I see the computer name in the wmpiconfig and I used the default
parameters, and in the wmpiregister I register the windows account I
am using, and it says "Password encrypted into the Registry." and I
click OK, and that's it. but every time I open the wmpiregister
again, I don't see the registered account.

I really appreciate your help,

Kind Regards,

Manal
