I find it very naive to say "read the man page to get started with a program", especially such a deep-level program like gprof. I tried it, read that I have to use the -pg switch, did that, and now I get an error msg that gmon.out cannot be found by gprof. One simple example how you actually do it would have resolved this. --ThorstenStaerk 06:44, September 25, 2009 (UTC)
