Today I tried to compile Emacs including the profiler like so:

CFLAGS=-pg LDFLAGS=-pg ./configure --without-x && make

Emacs creates a profile 

However, when I run ./emacs -Q it creates the same gmon.out at all the times, even if I run and make something in emacs a few seconds or 1 minute.

-rw-r--r-- 1 root root 4625 2009-03-25 11:45 gmon.out

Running
gprof emacs gmon.out | less

it shows just help information, nothing about the symbols of emacs.

Could you help me with some idea how to compile emacs includin the profiler?

This is a commentary from emacs.c:

  /* Set up for profiling.  This is known to work on FreeBSD,
     GNU/Linux and MinGW.  It might work on some other systems too.
     Give it a try and tell us if it works on your system.  To compile
     for profiling, add -pg to the switches your platform uses in
     CFLAGS and LDFLAGS.  For example:
       `make CFLAGS="-pg -g -O -DPROFILING=1" LDFLAGS="-pg -g"'.  */

Yes, IIRC the -DPROFILING is the important one, otherwise only temacs
is profiled.

Thanks. The profiler works now nice.
