oprofile unable to produce call graph
- by aaa
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?
