Description
Trusty's stable ppa has kernel modules v2.7 and everything else that's 2.6. It does not allow kernel tracing.
The nightly does not work either.
I confirm that the stable PPA does not work because of version mismatch between lttng-modules-dkms and the other packages.
The packages in the daily PPA are in sync, but there seems to be a linking problem:
[ 125.103539] lttng_tracer: Unknown symbol lttng_clock_unref (err 0)
[ 125.103564] lttng_tracer: Unknown symbol lttng_clock_ref (err 0)
[ 125.103601] lttng_tracer: Unknown symbol lttng_trace_clock (err 0)
Michael, who is also taking care of the Debian packaging, will look into it.
I applied loads of duct tape to the packaging of lttng-ust, lttng-modules and lttng-tools so that it builds. I copied a lot of stuff from the latest Debian package. I tested basic functionality of userspace and kernel tracing on Trusty, but not Java/Python tracing, so I don't know if that is properly configured.
I did not really pay attention to have a safe upgrade path. I know that Marc-André bumped into some conflicts between old and new packages while upgrading, but it could all be fixed by removing all lttng-related packages first.
