Profiler for g++

[SilentStrike]

Does anyone have any recommendations for a free profiler for code generated by g++? I searched google for g++ and profiler, but I didn't come up with anything.

Have you tried the GNU one yet? You probably even have it already.

I tried it, but it's weird. It doesn't work for my game. I compile it with the -pg flag and then run it, but instead of the game working like normal, it's just all black. The profiler output is obviously erroroneoss as well, the first few lines...

Flat profile:

Are you looking for something more like CPU monitors and stuff where you can see the realtime stats? Perhaps just build a small class to output what you need to the screen, like FPS and stuff.

I was looking for a profiler, one that shows the time spent in each function, etc, but using gprof and the -pg flag makes the program not work.

Same black screen odd behavior with the profiler from MSVC, guess I gotta start hunting for memory errors .
