[lttng-dev] Errors using lttng-modules v2.0-pre11

[Bernd Hufmann]

Hi Mathieu

Thanks, for the info.

I did as you suggested. Now I get the following error for "sudo lttng 
list -k"

Spawning a session daemon
FATAL: Module lttng_tracer not found.
FATAL: Module lttng_tracer not found.
Error: Unable to list kernel events
Error: Kernel tracer not available

BTW,  /lib/modules/3.0.4/build points to /usr/src/linux-3.0.4, so I 
think this is fine.

Please let me know how to continue.

BR,
Bernd
