Description
It seems like the dgf parser silently assumes that MPI_Comm is convertible to an int.
This is true for mpich where MPI_Comm is just a pointer. Unfortunately this is be no means supported by the standard. MPI_Datatype might as well be a class or a struct like in lam-mpi.
The attached code crashed with lam-mpi:
complexity.cc:12: error: invalid conversion from '_comm*' to 'int' complexity.cc:12: error: initializing argument 2 of 'Dune::GridPtr::GridPtr(const char*, int) [with GridType = Dune::YaspGrid<2, 2>]' complexity.cc:13: error: invalid conversion from '_comm*' to 'int' complexity.cc:13: error: initializing argument 2 of 'Dune::GridPtr::GridPtr(const char*, int) [with GridType = Dune::YaspGrid<3, 3>]' complexity.cc:14: error: invalid conversion from '_comm*' to 'int' complexity.cc:14: error: initializing argument 2 of 'Dune::GridPtr::GridPtr(const char*, int) [with GridType = Dune::AlbertaGrid<2, 2>]' complexity.cc:15: error: invalid conversion from '_comm*' to 'int' complexity.cc:15: error: initializing argument 2 of 'Dune::GridPtr::GridPtr(const char*, int) [with GridType = Dune::AlbertaGrid<3, 3>]'
