unknown symbol register_kprobe


I am trying to compile and insert this kprobe example(from RedHat Website) in my F17 kernel:

http://www.redhat.com/magazine/005ma...robebio_c.html

and this makefile: http://www.redhat.com/magazine/005ma.../makefile.html

but when I try to insert module into kernel, I see this error message: Error: could not insert module ./gooran_module.ko: Unknown symbol in module. dmesg says:

[ 3533.204708] gooran_module: Unknown symbol register_kprobe (err 0) [ 3533.204750] gooran_module: Unknown symbol unregister_kprobe (err 0)

Can anyone help me?

Well in the link the includes are missing. Did you include the following?
Code:
#include <linux/modules.h>
#include <linux/kernel.h>
#include <linux/kprobes.h>
#include <linux/ptrace.h>
* Hope this is still relevant to you.
