Profiling with GPROF

hi all,

I am trying to instrument a DLL, which will be loaded by a third party program.
So I compiled and linked the DLL with -pg flag. But when I ran the program, the profile data does not get generated ( the gmon file does not get created ).

Is it not possible to profile a dll like this ?

Thank you.

I have not used gprof but there are 2 possible reasons (from general point of view)
1. You may need recompile also the calling exe the same way
2. You may need to specify module of interest for the gmon before you start the application

I have used gprof . . .

Yes, I think you need to, though I've never tried profiling DLLs either.

No, you don't need to do this. Once a program is compiled with -pg, when run it generates the GPROF file. This can then be parsed with

Code:

---

$ gprof gmon.out

into stdout.
