MPI_Comm_f2c

Hi, I am facing an error, but I can not find info about it....

% _mpirun -np 4 julia MUMPS.jl_                                        
*** The MPI_Comm_f2c() function was called before MPI_INIT was invoked.
*** This is disallowed by the MPI standard.

Any ideas? R

What's in MUMPS.jl_? How did you install MUMPS? Does it work with the script in examples/?

Hi, I tried the suggested script and also reinstalling MPICH via brew and I think the problem is connected to MPI.jl

Sorry for the delay here. Is this on Linux?
