Hi Anna, I notice that your gcc and mpi are quite old. You probably want to run brew update brew upgrade to have more recent versions. Regards, David On Wed, 9 Aug 2017 at 10:06 Homolya, Miklós <m.homolya14@imperial.ac.uk> wrote:

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
