I experienced this issue with a distro kernel that had backported 
patches that changed some internal APIs. That kernel was still 
advertizing the same version number, so lttng-modules ended up using the 
wrong code path.

See http://bugs.lttng.org/issues/838

I'm not sure about your other compilation error though, I don't remember 
seeing that one. But it may be due to the same reason.


HTH,
