I just did:

cat hello.c

main()
{
        printf("Hello warudo\n");
}

gcc -pg hello.c
a.out
ls -l
total 610
-rwxrwxr-x   1 andy     tek       187472 Mar  5 13:41 a.out*
-rw-rw-r--   1 andy     tek       101286 Mar  5 13:41 gmon.out
-rw-rw-r--   1 andy     tek           40 Mar  5 13:41 hello.c

gprof

 ..... lots of stuff...


This was on solaris 2.5.1, with gcc 2.7.2.2. on linux RH 5.0, it
"works" but the output lack details, and the gmon.out is very small...

-rwxr-xr-x   1 andy     users       12686 Mar  5 12:49 a.out*
-rw-r--r--   1 andy     users         194 Mar  5 12:49 gmon.out

Also notice the a.out file is rather small...

Not sure what it happning....

The only thing I did find out is that the time on my linux box is
wrong :)
