Which distro / version are you running? It appears that the sem_open
call has failed on this platform.

There does appear to be a mistake in the code though with the error
reporting. 'perror' should be used instead of 'error'. The line
number in the config file isn't related to this error report.

Hello Shaun,

This system is a custom distro, based on debian and currently built around kernel 2.6.35.8. Is sem_open introduced only in DAHDI 2.9 ?

Maybe the problem is lack of tmpfs?

statfs("/dev/shm", 0xbff88568) = -1 ENOENT (No such file or directory)

Is this a new requirement for DAHDI?

Yes. It was added in [1] in order to prevent errors when multiple
invocations of dahdi_cfg are run in parallel. I've updated the error
messages [2] on the master branch of dahdi-tools. That might provide
some more information about why sem_open is failing on this
platform.

tmpfs is not a requirement per-se, but it's how most POSIX libraries
on linux (including the one installed on your system) implement the
named semaphores.

Well, I created /dev/shm and mounted tmpfs on it, and the problem is no more. Just creating /dev/shm was not enough.

thanks.

Just one last question: do you have another suggestion about this?

thanks.

Not really. There are other ways that dahdi_cfg could serialize
itself, but POSIX semaphores are widely deployed on systems that are
installing newer versions of DAHDI.

Although, dahdi-tools should probably have a configure script test
for a working implementation of sem_open and use another mechanism
if it is not available.
