That's right. There already exist some MPI installations on this system.

I receive this error when making MPICH 3.3.2 itself, not when compiling some code with mpicc. So It's not clear what you mean about using the correct mpicc.

Thanks. Arham

Hi Arham,

I think you have multiple MPI installations mixing up. Please double check that you are using the correct `mpicc` and check the results with `ldd`.

Hello.

Despite I have disabled fortran by --disable-fortran, I receive errors related to fortran when compiling MPICH 3.3.2.

Example:

.../linux/mpi/intel64/lib/libmpifort.so.12: undefined reference to `PMPI_Type_create_f90_complex'

How can I get rid of those errors without changing other installed softwares?

Please find attached m.txt and c.txt files.

Kind regards,

Arham
