yes - these 2 functions can have fortran stubs autogenerated. Removing the 'C' - and then running configure [which does an equivalent of 'make allfortranstubs'] - and 'make all' would be the steps.. Satih On Mon, 18 Jul 2016, Patrick Sanan wrote:

I'd like to use VecGetLocalVector and VecRestoreLocalVector from Fortran.

It appears that these are not covered by the Fortran interface, based on the fact that they don't appear in my include/petsc/finclude directory anywhere, even though other related functions do.

This seems to be confirmed by the fact that this function has the "comment-only" Sowing block in src/vec/vec/interface/rvector.c and does not appear in the ftn-custom (or f90-custom) directory there.

I'm new to using Fortran directly with PETSc. I can delete the "C" from the Sowing blocks, rebuild the library, and link, but I'm not confident enough to say that this worked yet. Should that be all that is required to make these functions available?
