how do i profile a program using the gcc compiler. I read in the manual that "-p" or "-pg" does the job but i just can't get it to work :S. And one more thing. What is the linux couterpart of "wglGetProcAddress" ? [edited by - browny on August 3, 2003 3:30:33 PM]

-pg is the normal flag for profiling. What do you mean by " can''t get it to work"?

well.. i compiled the source with "-p" or "-pg" and then ran the program normally. After that i am supposed to run "prof" right ? But it says some "a.out" or something is missing ! What''s that ?

Supply the filename of the executable you would like profiled as a parameter to the profiling program.

What you do is run a.out normally and it will generate a gmon.out file. You then run gprof:

gprof a.out

and it will generate the profile tree for you. I also use a GUI called kprof which makes it much easier to see what is going on.

glXGetProcAddress

extern void (*glXGetProcAddressARB(const GLubyte *procName))(void);
