It seems like with this particular commit, it's not possible to run
cyclictest on arm32 systems anymore. I guess due to missing NUMA
support?

Yes, your distro needs to provide libnuma. cyclictest runs fine on arm32
with the library.

Just tested on a dual core Cyclone V:

root@tsn:~/rt-tests# ./cyclictest -S -m -p 99 --secaligned
FATAL: Couldn't initialize libnuma

I think you would see the same error when trying to use the '-a' option
without the patch. The dependency is not new.

I've used the current unstable/devel/latest branch. Any suggestions?

The simplest thing is obviously to get libnuma on your system. I assume
this is not so simple in your case. In this case you could build
cyclictest a static binary.

First, build numactl as static libary:

  ./configure --enable-static && make

and then rt-tests with

  CFLAGS="-static -L../numactl/.libs/" make

Thanks,
Daniel
