Profiling and generating call graphs

[Andrea Crotti]

I'm trying to use the wonderful [1] gprof2dot to generate graphs of
function calls.

And I think I'm missing something because I don't get all the possible
calls and the percent of time used.
I added all the possible options found like
gcc -pg -g (when compiling)

And for gprof and gprof2dot
gprof --static-call-graph -m 0 $PROG | $GPROF2DOT -e0.01 -n0.01

But still I don't get anything really that makes sense.
Any idea?
Thanks

Nobody using gprof?
Maybe could you suggest something else to generate nice call graphs from
code execution?

Thanks
