Intel MPI 2019 always using gcc version 4.9.3

Question

Is there a way to specify the GCC version in intel MPI while I use the mpicc command to compile a program?

Does it not respect the `CC` environment variable mentioned in the man page? (At least the OpenMPI version of `mpicc` mentions that.) — Peter Cordes, Sep 17 '21 at 05:20
How to providing the CC flag to OpenMPI version of mpicc? Is it like — Sap BH, Sep 17 '21 at 05:25
It's not a flag, it's an environment variable. In a shell command, you can set it for a command like `CC=something some_command -args` just like normal. — Peter Cordes, Sep 17 '21 at 05:46

Working now.

The make the mpicc for Intel MPI to pick a specific gcc I used the option -gcc-name=path/bin/g++.

mpicc -gcc-name=path/bin/g++ text.cpp
