I am compiling an application using openmpi 3.1.1. The application is mixed Fortran/C/C++. I am using the intel compiler on a mac pro running OS 10.13.6. When I try to use the mpi_f08 interface I get unresolved symbols at load time, specficially _mpi_f08_types_mp_ompi_comm_op_ne_, _mpi_f08_types_mp_ompi_datatype_op_eq_, _mpi_f08_types_mp_ompi_op_op_eq_, _mpi_f08_types_mp_ompi_request_op_ne_, and _mpi_f08_types_mp_ompi_win_op_eq_. Generally the comparisons are being done against the appropriate NULL object, such as MPI_COMM_NULL. These routines appear to be present in the dylib objects created when I built openmpi, and I verified that the installed permissions are correct with user and group having read and execute permission as appropriate. Has anyone else seen this problem, and if some do you have any suggestions as to how to resolve this issue? Fortunately for me, I have the option to not use the f08 interface, and in this case everything works, but I would like to understand why using mpi_f08 fails to load for me.
