oprofile

hello

I am trying to use oprofile to generate call graph. Compiler is g++, platform is linux x86-64, linker is gfortran

C++ code is compiled with -fno- omit-frame-pointer. oprofile is started with --callgraph=25. report I run with --callgraph.

the call graph is produced but it's only includes self time, which is not much use

what am I missing?
