Use a more recent version or a different compiler which means that my GCC 4.1 compiler is too old to build the code (something i do not have control over..It is a cluster of the Uni where I work). so I tried another compiler ifort: ./configure --enable-mpi=yes FC=ifort but now I get another error: ============================================================================== === Multicore architecture support === ============================================================================== checking whether to enable OpenMP support... no checking whether to build MPI code... yes checking whether the C compiler supports MPI... no checking whether the C++ compiler supports MPI... no checking whether the Fortran Compiler supports MPI... no checking whether MPI is usable... no configure: error: MPI support is broken - please fix your config parameters and/or MPI installation Agaiin, I tried ti give a path for the mpi compiler: ./configure --enable-mpi --with-mpi-prefix=/usr FC=ifort WHICH APPARENTLY SOLVED THE PREVIOUS ERROR: ============================================================================== === Multicore architecture startup === ============================================================================== configure: Initializing MPI support configure: looking for MPI in /usr checking for a MPI C compiler... /usr/bin/mpicc checking for a MPI C++ compiler... /usr/bin/mpicxx checking for a MPI Fortran compiler... /usr/bin/mpif90 configure: creating wrapper for MPI Fortran compiler configure: GPU support disabled from command-line But stranegly enough got me back to the furst error although I am using ifort!! checking whether the Fortran compiler provides the iso_c_binding module... configure: error: Fortran compiler does not provide iso_c_binding module. Use a more recent version or a different compiler so what is going on?? please can anyone help me on this..Thank youu Elio University of Rondonia Brazil Classification: UNCLASSIFIED Caveats: NONE
