[Jérémie Galarneau]

Hi Claudiu,

I'm the mentor assigned to the prospective "Trace probe support in C++" project.

I'd recommend you get familiar with one of the lttng-ust example
application (in doc/examples), compile and run it, and read back the
resulting trace using Babeltrace. This will give you an idea of how
tracepoints are integrated in an application to be instrumented. I
have recently proposed a patch that adds example applications and
plain, automake-less, Makefiles to lttng-ust[1]. Clone my personal
development branch[2] to find it already applied.

You will also want to have a look at "tests/hello.cxx" in lttng-ust's
source tree which demonstrates that a C++ application can be compiled
even though a tracepoint header file is included. As explained in that
test's README, the tracepoint provider is compiled as a C library and
then linked into an application compiled as C++.

The objective of this project is to eliminate this intermediate step
and let C++ developers build them directly into their application
as-is. I can only suggest you try to compile your test application and
providers as C++ and work your way through the errors and warnings.
You'll never let anyone tell you C and C++ are the same again!

Thanks for reaching out,
Jérémie
