Aborting...Hi,
Need your help to figure why those errors are occurring. I had a look on src code of both openmpi and xgboost but is not obvious to me how these MPI::XXXX are supposed to be resolved.

See https://github.com/open-mpi/ompi/issues/3173 the openMPI CXX interfaces were removed in 5.0 following their 3.0 deprecation xgboost needs to convert its use to the C interface as was done in for example https://github.com/INCF/MUSIC/commit/16 … 87a1f5a1ad or at least test for the presence/absence of the CXX interface and not enable OpenMPI use accordingly.

Thanks loqs, that was very helpful to understand.
