[lttng-dev] Installing LTTNG on beaglebone black or rasberry pi

[Nwafor, Ebelechukwu]

Hi Jonathan. Thank you for your response.

On the beaglebone black, i tried building lttng-tools, lttng-modules-dkms
and lttng-ust-dev from source v2.8.1 by following the documentation.
lttng-modules-dkms runs fine but the module does not show up on the list of
running modules when i issue an lsmod command. Also, i run into errors
while trying to build and compile lttng-tools. Beaglebone black runs on
debian. Linux beaglebone 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015
armv7l GNU/Linux


On the raspberry pi, I use the commands, apt-get install lttng-modules-dkms
lttng-tools lttng-ust-dev. Everything seems to work fine with the exception
of lttng-modules-dkms which does not show up on the list on running
modules. Also, every time i try to view available kernel events, it comes
up with an error saying unable to list kernel events: kernel tracer not
available. The LTTNG version installed using apt-get is 2.7.1. I am running
ubuntu mate OS. Below are the output while installing lttng-modules-dkms

2 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n] Y
Setting up linux-headers-4.4.0-22 (4.4.0-22.40) ...
Setting up lttng-modules-dkms (2.7.1-1) ...
Loading new lttng-modules-2.7.1 DKMS files...
First Installation: checking all kernels...
dpkg: warning: version '*-*' has bad syntax: version number does not start
with digit
It is likely that 4.4.30-v7+ belongs to a chroot's host
Module build for the currently running kernel was skipped since the
kernel source for this kernel does not seem to be installed.
