lttng-tools has been broken on uClibc/musl since a long time due to dlmopen() and LM_ID_BASE not being implemented. The issue has been reported to the upstream lttng developers more than two months ago [1], and no fix has been provided. Therefore, it's time to disable it on uClibc and musl. Fixes: http://autobuild.buildroot.net/results/f9e82a87618bcdcd46d670697b5ac75836f7250d/ (uclibc) http://autobuild.buildroot.net/results/cb0952483b580b053a585760e59d78d11f46fc60/ (musl) [1] https://lists.lttng.org/pipermail/lttng-dev/2017-February/026921.html Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Userspace utilities for the LTTng 2.x tracing
|
|
infrastructure.
|
|
|
|
Those utilities are required on the target system to start
|
|
and stop tracing sessions. Analysis of the trace can be done
|
|
on the host machine using the babeltrace utility. This
|
|
utility is automatically built by Buildroot in
|
|
$(O)/host/usr/bin/babeltrace, as a dependency of
|
|
lttng-tools. However, there is also a lttng-babeltrace
|
|
package for the target, if babeltrace on the target is
|
|
interesting.
|
|
|
|
If userspace tracing is desired, you need to enable
|
|
lttng-libust.
