There are numerous examples of this problem in the amber mailing list

I occurs because the compiler you used to build your MPI library is
different from the compiler you used to build amber. You need to download
the source code for the mpi implementation you want to use and then build
it yourself using the compiler you want to use. Then make sure you setup
your paths correctly to pick up your own mpi installation and then recreate
the config.h file in amber and rebuild it and this time it should link

All the best
