#if defined(PETSC_HAVE_STDINT_H) && defined(PETSC_HAVE_INTTYPES_H) && defined(PETSC_HAVE_MPI_INT64_T) /* MPI_INT64_T is not guaranteed to be a macro */ typedef int64_t PetscInt64; #elif (PETSC_SIZEOF_LONG_LONG == 8) typedef long long PetscInt64; Verylikely you have a MPI that doesn't set 'PETSC_HAVE_MPI_INT64_T' - hence PETSc is not using int64_t. So you might have to just ignore the warnings.. Satish
