Hi all, I want to use PETSc with 64-bit indices with a Fortran90 code. It seems some PETSc functions have no problem, but some of the others do not accept 32-bit error code integer (e.g., "ierr" declared as PetscErrorCode type).
For example, call DMPlexGetChart(dm, pst, pend, ierr);CHKERRA(ierr) works okay, but call DMPlexGetDepthStratum(dm, 0, vst, vend, ierr);CHKERRA(ierr) gives an error regarding the datatype of ierr. The error basically leads: Error: Type mismatch in argument ‘b’ at (1); passed INTEGER(4) to INTEGER(8) I tried to declare ierr as integer(kind=8) type, but there are still some problems. If PETSc is configured with 32-bit indices, the Fortran code works without problem. What surprising to me is that as mentioned above, DMPlexGetChart() works okay, but DMPlexGetDepthStratum() does not work with "ierr (PetscErrorCode type)" variable with 64-bit indices. Can I get any comments on it? Thanks, Mike
