[lttng-dev] LTTng-modules install failed on a Parallella

[Thomas Bertauld]

Hi !

I recently began to work on a Parallella board and I wanted to try tracing
the ARM processor with LTTng before doing ant work with the Epiphany chip
(co-processor).

Nevertheless, i'm stuck with an error anytime i try to install the
lttng-modules. I've tried installing it from the official repositories and
from the PPA but none worked.

For now i only tried with the headless version of Ubuntu 14.04 (
http://www.parallella.org/create-sdcard/) for the Zynq-7010 (the processor
itself is a ARM Cortex A9).

The kernel version is 3.14.12, as seen in the error message below

*Loading new lttng-modules-2.4.0 DKMS files...First Installation: checking
all kernels...dpkg: warning: version '*-*' has bad syntax: version number
does not start with digitIt is likely that
3.14.12-parallella-xilinx-g40a90c3 belongs to a chroot's host*

And at this point the installation just stop and i'm back with the prompt.

Since i'm quite new in the LTTng universe i don't know what to do. I made
some researches on the subject but there was nothing for the Parallella. I
only found an answer for a similar problem suggesting to install the kernel
causing this trouble in the chroot environment, but i'm not quite sure how
to do this properly.

Thanks in advance !

Thomas.
