zoltan_test 'MPI_Errhandler_create’ was not declared in this scope

[fgfuchs]

When I am compiling, I get the following error:

opm-grid/tests/cpgrid/zoltan_test.cpp:100:9: error: ‘MPI_Errhandler_create’ was not declared in this scope
         MPI_Errhandler_create(MPI_err_handler, &handler);
         ^~~~~~~~~~~~~~~~~~~~~
opm-grid/tests/cpgrid/zoltan_test.cpp:100:9: note: suggested alternative: ‘MPI_Errhandler_free’
         MPI_Errhandler_create(MPI_err_handler, &handler);

My versions are: openmpi 4.0.1-1 zoltan 3.83-5

Can anybody help me with this?

MPI_Errhandler_create was deprecate in MPI 2 and removed, see https://www.open-mpi.org/faq/?category=mpi-removed#mpi-1-mpi-errhandler-create

OK, so this means I need to downgrade my openmpi version?

I will create a pull request based on your diff @akva2 . Thanks
