Profilling with CL and g++

Hi,
Its long time now I use CL and I'm quiet happy with it. Great product!
Now I have problem in profiling my code (I want to check functions that a time consuming and optimize code). After search I found that gprof and callgrind are valid options. Now I tried callgrind and I wanted to check out gprof. Looking at g++ manual I need to add -pg flag and so I did select in CL project and in compiling and linking CL logs that the flag is indeed included. but running CL does not output profile file. Is there any setting that I miss? any advice?
CL SVN (4.0.5646)
wxWidgets 2.9 (codelite is compiled against 2.8)
Ubuntu 12.04
gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)
Thanks In advance

Hi,
You may want to try the new callgraph plugin...

Hi Jeremie,
I hope you do fine
I have the plugin but I thought it needs the same file which my CL built app does not generate. Do I miss something here?

Have you checked into Working directory set by the project, and near the executable.
Are you sure you have -pg in compiler options AND linker options ?
(Note also the compiler option -g (to have debug info) is useful
and make sure that linker option -s (strip symbol) is not present)
It works fine here.

Let me check what is CWD. So far other options you mentioned looks fine!
Thanks!

That is the problem. I can see it but then It cannot open it says
The CallGraph plugin has suggested node threshold 1 to speed-up the call graph creation. You can alter it on the call graph panel.
clicking ok gives
Failed to open file CallGraph.png. Please check the project settings, rebuild the project and try again.
Don't know what is wrong but trying to figure out!

Hi Steve,
Do you have
dot in the path ? I suppose it's needed by this plugin...
