As already noted, gprof is the standard basic profiling tool for
anything compiled with gcc/g++.

I frequently use Valgrind (the 'callgrind' tool), particularly on
large applications because it offers better control of the profiling
and better visualization/browsing of the results.  Valgrind also
doesn't need a special recompile of the code.
