Can you try to compile and run this program and see what happens?

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

main(int argc, char **argv)
{
   int node;
   
   MPI_Init(&argc,&argv);
   MPI_Comm_rank(MPI_COMM_WORLD, &node);
     
   printf("Hello World from Node %d\n",node);
            
   MPI_Finalize();
}

For example, if the above code is saved as mpi_hello.c, then run
$ mpicc mpi_hello.c -o mpi_hello
$ ./mpi_hello
$ mpirun -n 3 ./mpi_hello

Hi Miklos,

I did run brew doctor already, fixed all the warnings and attempted the installation again. Same error. 

How do I fix the MPI C compiler then?

Thanks, 

Anna.

Hello Anna,

Apparently you MPI C compiler is not working. Are your brew packages up-to-date, and is the output of "brew doctor" clean?

Regards,

Miklos
