Should I be able to simply #include "prof.h" and use it? I tried the first example, but I'm getting this error:

# prof.h:274: PROF error (Invalid argument) Aborted (core dumped)

running through gdb gives me: Starting program: /home/john/Documents/c++/tmp/prof/a # prof.h:274: PROF error (Invalid argument)

Program received signal SIGABRT, Aborted. 0x00007ffff7745cc9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 56 ../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory.
