Hi,
nm --undefined-only *.o | cut -c12- | sort | uniq
would give you a list of all external symbols
nm --defined-only *.o | cut -c12- | sort | uniq
would give you a list of all defined symbols
now all enties in 2nd list, which are not in first list should be what you are
looking for ('comm' should be able to do that).
