I need to trace program flow (trace user function calls).
I have found a script xtrace from glibc which promises to do that. But if I
run it doesn't print anything except programs output.
How should I use it. It is neccessary to recompile the program with a
special option?

Or does there exist any other similar tool to xtrace?

As you mention glibc, I assume that your compiler is gcc.

Have a look at the -finstrument-functions option for gcc.
