Hi,
I’m trying to install lttng on my Jetson TK1, but I can’t build the lttng kernel module.
I’m running the last kernel available from JetPack2.1, Linux for Tegra r21.4, which is a LTS ubuntu 14.04.4 LTS (GNU/Linux 3.10.40-gdacac96 armv7l)
This kernel satisfies configuration required (CONFIG_MODULES,CONFIG_KALLSYMS,CONFIG_HIGH_RES_TIMERS,CONFIG_TRACEPOINTS).
I’m using the git tree on tag v2.8.0-rc1. Installation of userspace-rcu, lttng-ust, and lttng-tools was fine, but when I build lttng-modules I got this error related to the TP_FIELDS macro:

Any idea of the cause of this error ?
I saw the file arm-32-syscalls-3.4.25_integers.h is auto-generated, should the number match my kernel version ?
Thanks,
