Hi,
Is it possible to setup a function that returns the xeno version string ?
In cross compiled environment, this will permit to check at runtime that
you are running the program with the expected xeno libraries !!!
We have had following problem on the target we setted up:
kernel modules were right, but usr/xenomai/libs were coming from an
older xeno release !!
at runtime , our program had some bad issues !
Best Regards
Steph

I think Stephan has a different problem:

He dynamically linked against some old Xenomai lib over a new kernel,
right? That should be caught by the ABI check on library init these
days. Stephan, can you tell us which versions where involved here?

Not if the ABI numbers haven't changed, so the real question is: which
discrepancy did actually caused the issue, and does it reveal a lack in
updating the ABI revs, or a plain application issue.

YES, YOU ARE RIGHT , we linked 2.3.0 compiled programs against 2.1.2 libs

Unfortunately, our ABI revs between those versions are wrong then.
