Hi Raghu,

Did you have a look at the doc? [1] https://lttng.org/docs/v2.10/#doc-c-application

We will need the complete compile command, linker command used and that you identified the scenario [2] from the doc matching your situation.

[2] https://lttng.org/docs/v2.10/#doc-building-tracepoint-providers-and-user-application

Also could you give us the version of lttng-tools and lttng-ust installed?

Cheers
