Okay, fair enough for this test example.But the Salomé case is more complicated: extern "C" { #include <hdf5.h> } What to do here? The hdf5 prototypes must be in an extern "C" block, but hdf5.h #includes a file which #includes mpi.h... Thanks for the quick reply!
Yeah, this is a complicated example, mostly because HDF5 should really be covering this problem for you. I think your only option at that point would be to use the #define to not include the C++ code.
The problem is that the MPI standard *requires* mpi.h to include both the C and C++ interface declarations if you're using C++. There's no way for the preprocessor to determine whether there's a currently active extern "C" block, so there's really not much we can do. Best hope would be to get the HDF5 guys to properly protect their code from C++...
