undefined symbol: ompi_mpi_instance_null when translating from OpenMPI to Cray MPICH

[nhanford]

Hello,

When translating from ROCm-Aware OpenMPI 5.0.3 to ROCm-Aware Cray MPICH 8.1.19, I am getting the following errors:

/osu_allreduce: symbol lookup error: ./osu_allreduce: undefined symbol: ompi_mpi_instance_null

I am using the GNU toolchain. I have tried building a few different ways, but I keep hitting the error.
Please let me know if any additional information is needed.

Thanks,
Nate
