1. PETSC_FUNCTION_NAME_CXX is defined in petscconf.h which is created by
configure. Perhaps you need to rerun your configure
    if you updated from an earlier version. You can check in

       petsc-3.17.0/arch-linux-c-debug/include/petscconf.h

   for the macro

2. The PETSC_RESTRICT is a knock-on error from the last error.

  Thanks,

     Matt
