Hi Petsc Users I am trying to use the sequence of call DMLabelPropagateBegin(synchLabel,sf,ierr) call DMLabelPropagatePush(synchLabel,sf,PETSC_NULL_OPTIONS,PETSC_NULL_INTEGER,ierr) call DMLabelPropagateEnd(synchLabel,sf, ierr) in fortran.
I apologize if I messed something up, it appears as if the DMLabelPropagatePush command doesn't have an appropriate Fortran interface as I get an undefined reference when it is called. I would appreciate any assistance. As a side note in practice, what is the proper Fortran NULL pointer to use for void arguments? I used an integer one temporarily to get to the undefined reference error but I assume it doesn't matter?
