I tried updating everything; packages, kernel.
The is on a Beagle Bone Black. Kernel is now - Linux kossel
3.8.13-xenomai-r70 #1 Fri Jan 23 01:35:45 UTC 2015 armv7l GNU/Linux.
I followed the build instructions here...
http://www.machinekit.io/docs/developing/machinekit-developing/#get-source-and-build
and did a ./configure --with-platform-beaglebone
Any ideas?
I am guessing you are using a Wheezy based image with gcc-4.6
Preferably use a recent Jessie based image, which has gcc-4.9.2
Wheezy is only receiving security updates and next year will be dropped
completely by Debian.
At the very least, enable backports and install gcc-4.7.2 (and ensure
that it is selected , do gcc --version)
atomic operations are in the C11 standard, which 4.6 does not support in
any meaningful way and 4.7.2 only scantily

Thanks,
