Hi, I am trying to build MPE for use with OpenMPI. I built from source Version 1.10.1 of OpenMPI. I am using this version of MPE ftp://ftp.mcs.anl.gov/pub/mpi/mpe/mpe2.tar.gz Should this work fine? I followed the instructions to build like this: ${MPE_SRC_DIR}/configure MPI_CC=${OPENMPI_INSTALL_DIR}/bin/mpicc \ CC=<C_COMPILER_used_to_build_OpenMPI> \ MPI_F77=${OPENMPI_INSTALL_DIR}/bin/mpif77 \ F77=<FORTRAN_COMPILER_used_to_build_OpenMPI> \ --with-java2=/usr/local/j2sdk-1.4.2 --prefix=<MPE_INSTALL_DIR> make make install I keep running into problems with conflicting declarations log_mpi_core.c:5611: error: conflicting types for 'MPI_Type_struct' /u/hschilli/local/include/mpi.h:1796: error: previous declaration of 'MPI_Type_struct' was here I think the issue is that MPE's declaration uses some const qualifiers while OpenMPI does not. I tried hacking my way through this with the macro HAVE_CONST_IN_MPI_DECL and MPE_CONST but no luck so far. What am I doing wrong? Thanks in advance. --------- Herb Schilling Scientific Applications and Visualization Team http://ocio.grc.nasa.gov/gvis Office of the Chief Information Officer NASA Glenn Research Center [email protected]<mailto:[email protected]>
