Hi Marco,
Kindly ignore my below email, as the problem is solved. Actually, i had
mingw already installed in my system previously, and its path was set in
environment variables. And, the cygwin version I installed didn't have
gcc/g++ packages installed. So, when i was running, mpicc, it was by
default picking the gcc/g++ of mingw. So I removed path of mingw, and
installed packages in cygwin, and now mpicc/mpic++ etc are working. T
Thanks again for your kind help.

Dear Marco
Once again thank you for kind help. As you suggested, I installed Cygwin,
along with the OpenMPI packages, from the links you sent.
When I run this example (hello.c):
#include <stdio.h>
#include <mpi.h>
int main(int argc, char *argv[]) {
int numprocs, rank, namelen;
char processor_name[MPI_MAX_PROCESSOR_NAME];
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Get_processor_name(processor_name, &namelen);
printf("Process %d on %s out of %d\n", rank, processor_name, numprocs);
MPI_Finalize();
}
Now I am getting the following error:
OSMANK@osman /home
$ ls
file1.cc hello.c OSMANK
OSMANK@osman /home
$ mpicc hello.c -o hello
hello.c:1:17: *fatal error: mpi.h: No such file or directory*
compilation terminated.
OSMANK@osman /home
I have also tried a c++ version (mpic++) with .cc file and it also gives
the same error. Can you kindly suggest what is wrong here. Do I need to set
any paths? The command such as mpirun or mpicc etc itself does not give
error, but asks for the file inputs.
Thank you in advance.
