Hi,

As a follow-up to this email thread, 
https://www.mail-archive.com/petsc-users@mcs.anl.gov/msg44070.html

Are DMLocalToLocalBegin() and DMLocalToLocalEnd() really available for DMPlex with Fortran on the latest version of PETSc (3.17.99 from GitLab)? Matt commented that the Fortran bindings were updated so that those functions must be available in the latest version of PETSc, however, it seems still they are not working from my test with DMPlex in Fortran. Can anyone provide some comments? Probably I am missing some mandatory header file? Currently, I have headers;

#include "petsc/finclude/petscvec.h"
#include "petsc/finclude/petscdmplex.h"
#include "petsc/finclude/petscdmlabel.h"
#include "petsc/finclude/petscdm.h"

The source for these functions is in

  src/dm/ftn-auto/dmf.c

Is it there for you? If not, you can run

  make allfortranstubs

Fortran functions are not declared, so the header should not matter for compilation, just the libraries for linking.

  Thanks,

     Matt
 
Thanks,
