I'm trying to build the Salomé engineering simulation tool, and am

can
be reproduced by trying to compile a C++ file with:
extern "C"
{
#include "mpi.h"
}
At the end of mpi.h, the C++ headers get loaded while in extern C
mode,
and the result is a vast list of errors.
Yes, it will. Similar to other external packages (like system
headers), you absolutely should not include mpi.h from an extern "C"
block. It will fail, as you've noted. The proper solution is to not
be in an extern "C" block when including mpi.h.
