gcc compiling for profiler question

[Boltar]

Hi

I'm trying to create a gmon.out file with gcc so I can run my program
through gmon. However the -pg option doesn't seem to work. Is there a
trick to generating this file?

Thanks for any help

I meant gprof , not gmon.

You must run the program once before the output is generated.
Same as gcov.

Works now. I assumed it ran the prog in situ like gdb.

Thanks

Look up gprof (either "man gprof" or "info gprof" or both). This
is off-topic on c.l.c.
