I have an embedded box running 2.6.18 linux with rt patch.

I am developing an  userspace application which need timer_create() .
I have a big desktop machine with a 4 GB ram, running only linux
2.6.18 ( not rt linux ) . I would like to compile and test it on this
Desktop PC .

I compiled my program and linked with librt.a on my Desktop PC. But
when i run my program , it says

undefined symbol: pthread_once

what could be the problem, ???
