Hi, I was wondering if in $PETSC_DIR/include/finclude/petscdef.h :
50 #if defined(PETSC_HAVE_MPIUNI) 51 #define MPI_Comm PetscFortranInt 52 #define PetscMPIInt PetscFortranInt 53 #else 54 #define MPI_Comm integer 55 #define PetscMPIInt integer 56 #endif the integer declaration should not be changed to something dependent on PETSC_SIZEOF_INT.
