The message reports that it tried to compile a very simple MPI program
with exactly the command line you gave it, it seems to have found the
header mpi.h (no complaint about it) but it could not find the function
MPI_Init(), which should be present in any MPI library.
This is something related to your system, so I can't help you with the
details, but find out which commands you need to use to compile the
int main ()
int argc; char **argv; MPI_Init(&argc,&argv);
