<div>Recently I started to integrate LTTNG in Android ICS by
compiling each package, each dependency, by using the Android
build system. It is a lot of work because I met different
problems and to be sincere, I do not know if at the end will
work and I do not know how much I will need to modify the
sources in order to work.<br>
</div>
<br>
My questions are about this integration. I mention that I read a
lot of discussions about this on Internet, on this mailing list,
but the things are still not very clear for me.<br>
<br>
It is ok? what I am trying to do ? to integrate and build by
using the Android build system.<br>
Could you give me some guidelines, indications about how I
should proceed, maybe a tutorial or maybe some android make
files/patches that would help me to see how the job must be done
and if I am doing it right ?<br>

Hi!<br>
<br>
A group of students at Ecole Polytechnique of Montreal worked on
that topic. They were able to get a kernel trace from Nexus 7
tablet. It required small modifications to tools, and cleanup is in
process to merge patches upstream[1]. Kernel tracing is working,
while UST requires still some work on few bugs. I received the
confirmation from the students the build scripts they created will
be released under open source licence soon.<br>
<br>
LTTng tools depends on two libraries libpopt and libuuid that are in
android sources. It's simpler to just build the whole thing. Once
tools are built, then they can be installed on the target. <br>
<br>
A tutorial would be a must! I'm installing it on my phone right now,
if nobody else did the tutorial by then, I will do so. That would be
great if this was to be integrated in the dev tools in the android
source repo!<br>
<br>
Cheers,<br>
<br>
Francis<br>
