I have a similar problem trying to install xenomai 2.6.0. In my case 
latency works correctly, but trying to compile examples gives me the 
same 'unresolved reference' error. I noticed this first trying to 
compile RTXI, which also gives me

I did it before with Xenomai 2.5.6 and did not recall such a linking 
problems. I read before that it might be causes by cross-compilation 
being messed up, but in that case I do default compilation on linux 
2.6.38.8. I did not try 2.5.6 again to check if the problem remains for 
2.5.6, I can try to do that.

Best wishes,
