<p>One way to know if your app is really compiled with

You would typically see something like this: <br>

If you see nothing, as Mathieu said, you can check the individual
make commands and see what flags are being used on the command line.<span class="m_-7198374342017345733gmail-m_-789035653171103869HOEnZb"><font color="#888888"><br>

<div>Hi,</div>
<div> I am trying to use Function Tracing for my
application running in 32-bit ARM Platform. I have
added below lines in my makefile for enabling Trace
Data for function tracing </div>
<div><br>
</div>
<div>AM_CFLAGS += -g -O0 -finstrument-functions</div>
<div>AM_CXXFLAGS += -g -O0 -finstrument-functions </div>
<div><br>
</div>
<div>**(My App have both C && CPP files, So I
added CFLAGS & CXXFLAGS). </div>
<div><br>
</div>
<div>I am running below commands,</div>
<div><span style="white-space:pre-wrap"> </span>$lttng create
session1</div>
<div><span style="white-space:pre-wrap"> </span>$lttng

</div>
<div>Its showing nothing.</div>
<div><br>

<div>I tried with below event-enable command also. There
is no data</div>
<div><span style="white-space:pre-wrap"> </span>$lttng
enable-event -u -a --loglevel TRACE_DEBUG_FUNCTION </div>

</div>
<div>But If I use the command, "lttng enable-event -u
-a" for enabling the event, I am getting below output
