But using -mat_fd_type ds vs -mat_fd_type wp does produce (slightly) different convergence histories? Barry

If your fortran function includes petscsnesdef.h does it work ok?

No, unfortunately.

(I forgot to say, I'm doing #include <petsc/finclude/petsc.h90> in my code.)

Just pass in the string 'ds' it looks like our Fortran include files are not correct.

This does compile, but doesn't look like it is actually doing anything- i.e it's not giving the same behaviour as if I set "-mat_fd_type ds" on the command line. It just gives the default wp behaviour.
