Hello,
The cross-compiled glibc that is included in ELDK 4.0 doesn't seem to
have support for POSIX semaphores. I get the following runtime errors:
sem_open: Function not implemented
when trying to implement a named semaphore, and
sem_init: Function not implemented
when trying to implement an unnamed semaphore.
Does anybody know if POSIX semaphores have been ported to ppc_6xx, and
if so, where I could find a binary copy?
thanks,
Ben

This normally works in every modern glibc. Maybe you were using an
set of kernel headers that is too old. Make sure that you have
up-to-date version of both kernel and glibc and that you use the
kernel header files you get from 'make headers_install' in the kernel.

I haven't had a chance to try this out yet, but appreciate your tip!
