It depends on how you compile your program. If you're using MPC, they
should be set. If you're using a hand-written makefile, then you're on
your own and you don't necessarily need them, though they can be usefull
shortcuts.

Good, this is indeed what you needed to do.

You probably need to add -lTAO_CosNaming to your link command.
