Apologies, will do next time. That would also have helped me realize that I had pushed to my own clone, not petsc-3.3 or petsc-dev repository... I am attaching the patch I was planing on submitting. Out of curiosity, what is the rationale for not wanting an explicit interface? As far as I understand, the fortran standard mandates an explicit interface in this situation (array of strings). I would understand in the situation of pure f77 compatibility for instance, but we threw this away with the iso_c_binding module anyway... Perhaps introducing f2003 in petsc was a bad idea, considering the large variety of compilers you need to support. If you feel that it introduces more issues than solving problems, feel free to strip the PetscOptionsEnum and PetscBagRegisterEnum bindings. They could easily be packaged separately for the few people who will ever need them. -------------- next part -------------- A non-text attachment was scrubbed...
