Details

Things don't work well. Here's a sample program:

#include "mpi.h"
#include <stdio.h>

int main(int argc, char *argv[])
{
    int rank, size, len;
    char version[MPI_MAX_LIBRARY_VERSION_STRING];

    MPI_Init(&argc, &argv);
    MPI_Comm_rank(MPI_COMM_WORLD, &rank);
    MPI_Comm_size(MPI_COMM_WORLD, &size);
    MPI_Get_library_version(version, &len);
    printf("Hello, world, I am %d of %d, (%s, %d)\n", rank, size, version, len);
    MPI_Finalize();

    return 0;
}
