[lttng-dev] Arch arm cross-complie lttng-modules

[Marko Vucak]

Hi

When trying to cross-complie lttng-modules with Linux 3.14 ARCH ARM build
using this command:
make KERNELDIR=/home/muser/Projects/st-linux-mainline/

I get this errors:

                 from include/linux/ftrace.h:18,
                 from include/linux/kprobes.h:42,

Additional info:

Linux is 3.14 build with:
make ARCH=arm CROSS_COMPILE=arm-v5te-linux-gnueabi-

LTTng modules used are downloaded from here:
http://lttng.org/files/lttng-modules/lttng-modules-2.7.1.tar.bz2
I tried clone it from https://aur.archlinux.org/lttng-modules.git but
doesn't exists anymore.
