I think that makes sense - the debug information has stored the path of <br>
the build environment which is the sysroot portion.<br>

I don't see anything more that stands out.<br>
<br>
I'm going to step back a bit to make sure I have correct understanding <br>
of your situation.<br>
<br>
Based on your previous statements, it sounded like you weren't sure if <br>
your application is statically linked or not. This is different than <br>
using a statically linked probe provider.<br>
<br>
You can verify by running `ldd /path/to/my_app`. lttng-ust doesn't <br>
support being statically linked, it is always loaded dynamically. The <br>
trace probe providers (TPPs) may be statically linked, which is different.<br>
<br>
You mentioned earlier that the building scenario you were using <br>
resembles the hello world example. To confirm my understanding, do you <br>
mean the hello-static-lib example in lttng-ust/doc/examples? In the <br>
docs, this is called "The instrumented application is statically linked <br>
with the tracepoint provider package archive file". Note that the final <br>
application still uses dynamic linking (`-ldl -llttng-ust`, and the <br>
absence of `-static -static-libc` when creating the final executable).<br></blockquote><div><br></div><div><div>I may have not been clear. Most of the application components are
statically linked but I think there are some that are built as shared
objects (.so's) so that's what I was referring to. I know that
lttng-ust is dynamically linked ... I think the lttng-ust docs say this
is only option but also makes reference to the fact static linking was
once possible (in some versions of the documentation) but not supported
anymore (I probably have the docs memorized by now ha, ha ... I've
looked at many, many versions of them).</div><div><br></div><div>Just for full disclosure my ldd looks like:</div><div><br></div><div><span style="font-family:monospace"><span style="color:rgb(0,0,0);background-color:rgb(255,255,255)"> linux-vdso.so.1 (0x0000ffffab196000)

My current understanding is that the statedump tracepoints are <br>

is run (at least for C programs). If you do the following test, I think <br>
you should be able to see the statedumps. Could you confirm if you have <br>

<br>
Ultimately, given the bespoke environment, build steps, and application <br>
it's tough to diagnose a lot of things that we would go over with a fine <br>
tooth comb: seeing how the TPPs are built and linked, seeing how the <br>
application is built and linked, analyzing what's happening at runtime, <br>
having a coredump that allows us to see the variables, etc.<br>
<br>
If you can provide a minimal reproducer, it's possible to dig further <br>
into it.<br>
<br>
Otherwise, to look in more detail at your specific project would be <br>
covered under a service contract (for which we can sign NDAs, etc. as <br>
needed). Feel free to reach out the <a href="mailto:sales@efficios.com" target="_blank">sales@efficios.com</a> to organise that.<br></blockquote><div><br></div><div><div>I understand but so far schedules & budget/priorities haven't

<br>
LD_PRELOAD has an effect if the application you are running is <br>
dynamically linked (note: the TPP can be statically linked inside an <br>
dynamically linked executable, and the preloads are still useful and/or <br>
needed in that case).<br>
<br>
The function of the helpers are to ensure that various system calls <br>
don't clobber things in use by lttng-ust. E.g., close() is shimmed by <br>
liblttng-ust-fd.so so that FDs that lttng-ust uses aren't suddenly shut <br>
by the program.<br>
<br>
If you want to see it in action, you could try an experiment with a <br>
slightly modified hello-static-lib application, with instructions in the <br>

<br>
The effect of the preloads such as liblttng-ust-fd.so are independent of <br>
how the TPP is built and linked to the application or library.<br>
