[lttng-dev] Issues on basic LTTng trace userspace (tutorial)

[MONTET Julien]

Hello the LTTng team !

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

Have you ever had those kind of issues ?
Could you advise me some debugging methods or solutions ?

Have a nice day,

Julien Montet
