need to profile the qt/cpp code with arm-linux-gprof

[Meenakshi Yakri]

Hi
I need to profile my qt project/cpp code how to do this.
I am working on ARM-Linux I have GCC
tried profiling with arm-linux-gprof but not working.. the steps i followed
to do this are
1. added the following lines in .pro file of my qt project
CONFIG += DEBUG
QMAKE_CXXFLAGS_DEBUG += -pg
QMAKE_LFLAGS_DEBUG += -pg
did qmake,, make
& after running it din't generate gmon.out
so i am not able to profile..

any other steps to do this profiling using arm-linux-gprof please tell
or any other profiling tools, how to get them & how to use please help
