>Thanks for yoru reply, but I don't really understand how to solve as I got problem loading the module, so I can't have any output to see .... So do you know what else can I do?
Provide more information please:
$ cat /proc/cpuinfo
$ oprofpp --version
and what is your linux distribution/kernel version ?

you probably don't have local apic (laptop ?) then oprofile try to use RTC
clock to get a sampling, RTC fail because you the kernel already use RTC,
you must either unload the RTC module or if the RTC is built-in in the
kernel you must recompile your kernel w/o RTC support
