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.
