I'm not sure why that software is defining MPI_BOOL -- that's bad form. MPI reserves the "namespace" prefix of MPI_ -- middleware and applications should not be defining new symbols with an MPI_ prefix (to prevent exactly this kind of confusion). -- Jeff Squyres jsquy...@cisco.com _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
