Then build the kernel again.

Then I checked weather xeno_rtipc.ko was loaded, it wasn't. I tried it with insmod and modprobe but both got error: Unknown symbol in module

The Dmesg:
[  230.190867] xeno_rtipc: Unknown symbol xnmap_delete (err 0)
[  230.190900] xeno_rtipc: Unknown symbol xnpipe_connect (err 0)

[  230.191180] xeno_rtipc: Unknown symbol xnmap_create (err 0)
[  230.191231] xeno_rtipc: Unknown symbol xnmap_remove (err 0)

[  230.191341] xeno_rtipc: Unknown symbol xnpipe_recv (err 0)



Do I need some other xenomai settings enabled or  libraries?

Please read our suggestions carefully: Go to your kernel build folder, invoke "make menuconfig" and check under Xenomai settings if RTIPC as well as XDDP are enable. If not, change that, rebuild, install, profit.
