Function Profiling

hi,

I have created one project in eclipse. I have updated my eclipse with Test and Performance Tools Platform (TPTP) tool. Now I got Profiling and Logging option.

While trying to create profile configuration, java application is available but there is no option for C/C++.

1. Is possible to do function profiling for c code in Eclipse?
2. In profiling configuration one of the option is there Attach to agent, in that how can add agent?

thanks,

No idea about profiling out of eclipse for c/c++ programms. However, you could try to compile your progamme on the command line. Just add '-ggdb -pg' to the compiler options. This will create a binary with profiling enabled.

When you run your programm and let it quit in a proper way, you will get a 'gprof.out' file in the CWD. You can examine this file with gprof like so:
gprof 'YOUR_BINARY' gprof.out

This will dump the function profiling data to STDOUT.

Basically, its what i stated:

Code:

gprof 'YOUR_BINARY' gprof.out

Maybe the following helps:
