Hi
the last problem seems to be a problem with lttng-tools v2.0_pre18.
After reverting to version lttng-tools v2.0_pre17 the problem is gone.
Could someone look into that?

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

Hello
I installed the lttng-modules v2.0-pre11 from source code (git
repository). The installation went without problems. But I'm getting the
errors below when executing "sudo lttng list -k".
I'm running Ubuntu with a kernel 3.04. lttng-tools version is v2.0-pre18.
Could someone please look into this problem and let me know how I can
overcome this issue?
BTW, before installing lttng-modules v2.0-pre11, I tried to upgrade to
the latest in master from an older version.
Please try to remove all lttng modules from your
/lib/modules/3.0.4/extra directory, go to your lttng modules tree, make
clean, make, and, as root, make modules_install.
This should fix it. I expect that currently your modules are built
against the wrong kernel tree.
If it does not fix it, investigate whether your /lib/modules/3.0.4/build
symlink points to a kernel tree (or kernel headers) that match your
running kernel.
Best regards,
Mathieu
