Many thanks for the answer
The demos xddp-echo , xddp-label and xddp-stream seems all to be working ok.
As sanity check, I copied xddp-echo.c to my workspace and compiled it
with the rest of our code.
Compilation goes ok, but execution fails with message:
socket: Address family not supported by protocol
This brought my attention to this:
http://xenomai.org/pipermail/xenomai/2014-February/030113.html
which says:
"Your application is likely not wrapping POSIX symbols properly, calling
regular socket() instead of the Xenomai implementation. "
We do things this way, possibly something is missing ?
exec_program(${XENOMAI_ROOT}/bin/xeno-config ARGS "--skin=native
