Re: Profiling GNU Octave

No success, the output is still empty:

index % time    self  children    called     name

                0.00    0.00       1/1           __libc_csu_init [16]

[9]      0.0    0.00    0.00       1         _GLOBAL__sub_I_main [9]

                0.00    0.00       1/1           __static_initialization_and_destruction_0(int, int) [10]

-----------------------------------------------

                0.00    0.00       1/1           _GLOBAL__sub_I_main [9]

[10]     0.0    0.00    0.00       1         __static_initialization_and_destruction_0(int, int) [10]

If you know what is happening, please share.

Nevermore! I added -O3 and it striped the profiling info.

Building again...

Hi,

I'm trying to do some profiling before add OpenMP constructs, however, gprof's output is showing empty. I have set both CXXFLAGS and LDFLAGS to include the -pg flag, don't know what is causing the profiler to miss the function calls:

index % time    self  children    called     name

                0.00    0.00       1/1           __libc_csu_init [15]

[9]      0.0    0.00    0.00       1         _GLOBAL__sub_I_main [9]

-----------------------------------------------

These are the only two calls captured and they have no practical meaning. Anyone knows what is happening?

Best,

Júlio.
