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
