I would like, at first, to thank you for your projet and your impressive work !
For the past few days I have been trying to learn how to use lttng (v2.12).
I followed the installation on your website for an Ubuntu 20.04.
The steps to get the trace of a Linux kernel and the babel trace are great !
However, I am stuck for the 'Trace a user application' : https://lttng.org/docs/v2.12/#doc-tracing-your-own-user-application
Compilation steps are ok, it launches without error but lttng
list --userspace
gives me nothing.I tried of course to add -L/usr/local/lib and -Wl,-rpath,/usr/local/lib
