[lttng-dev] compile error in lttng-ust-2.4.4

[Philippe Proulx]

Babeltrace <http://diamon.org/babeltrace/> offers a basic log-like text
output of the events. Babeltrace ships with Python 3 bindings so that you
can write your own analysis easily.

Trace Compass <http://tracecompass.org/> is a complete GUI environment
for viewing and analyzing traces.

See: <https://lttng.org/viewers/> and
<https://lttng.org/docs/#doc-getting-started>.
