What distribution are you on?
The kernel-version is:
Linux socfpga_cyclone5 3.10.31-ltsi-05082-g018fe6c #1 SMP Fri Mar 13 16:38:52
GMT 2015 armv7l GNU/Linux
We noticed that you had multiple lttng-modules recipes, could you do a
modinfo on one of the .ko generated on the yocto build?
find /lib/modules/`uname -r`/ | grep lttng | head -n 1 | xargs modinfo
It is best to have only one version installed to minimize version
incompatibility between LTTng component.
Lttng version is:
root@socfpga_cyclone5:~# lttng --version
lttng (LTTng Trace Control) 2.4.0 - Époque Opaque
I am using this version because it is the version included as a recipe in the
Yocto Daisy distribution for the Altera SoCFPGA.
Is it possible to share it with us (url/file) ?
As I am five hours or so in front of you guys, I shall try and get a build
working with the latest version of LTTng (2.6.0), but I am not a bitbake/yocto
expert
Neither am I :P. Looks like you can find up-to-date recipe here [1] .
You could also try their mailing list for help.
[1] http://packages.yoctoproject.org/rrs/recipes/1.8/M4/
And each time I try to change something, I end up with a whole raft of new
problems to solve.
Let us know what happen.
Cheers!
Jonathan
Thanks again,
Neil.

Hello,
When I create a session and try to capture some kernel traces I see
the following (first output from lttng-sessiond and then from the
tracing session):
I am using the following version of LTTng:
nbryan@meteor:/data/nbryan/Meteor/YoctoDaisy/poky/meta/recipes-kernel/
lttng$
ls -1
babeltrace_1.1.1.bb
lttng-modules
lttng-modules_2.3.3.bb
lttng-modules_2.4.2.bb
lttng-tools
lttng-tools_2.3.1.bb
lttng-tools_2.4.0.bb
lttng-ust
lttng-ust_2.3.1.bb
lttng-ust_2.4.0.bb
Thank you for any clues,
Regards,
Neil.
