POSIX semaphores in CentOS 5.1?

[MHR <mhullrich@xxxxxxxxx>]

According to the man pages for sem_wait, etc., POSIX semaphores are available in Linux 2.6 (with the right NTPL threading in glibc).

However, I have a program that compiles just fine but won't link because it can't find the library for the semaphore operations.

What am I missing?

I ran a find and grep through all the libc's on the system and they turned up nothing:

$ find /lib /usr/lib -name "*libc\.*" -print -exec nm {} 2>/dev/null \; | grep sem_

(no results)

Time is critical (yeah, I know...).

Thanks.
