I'm using Debian and it provides libnuma.

Static building with the newest numactl library also doesn't work:
|root@tsn:~/rt-tests# file cyclictest
|cyclictest: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=248eaf8847544423dc51c6ceea18bbffc487991e, with debug_info, not stripped
|root@tsn:~/rt-tests# ./cyclictest
|FATAL: Couldn't initialize libnuma
|root@tsn:~/rt-tests#
Hmm.
Thanks,
Kurt
