[OMPI users] Using custom version of gfortran in mpifort

[Mahmood Naderan]

Hi,
The mpifort wrapper uses the default gfortran compiler on the system. How
can I give it another version of gfortran which has been installed in
another folder?

Regards,
Mahmood

The best way is to specify the compiler(s) that you want Open MPI to use when you configure/build Open MPI itself:

That will propagate your compiler choice down into the wrapper compilers.
