I tried running these examples in two different ARM aarch64 kernels, but I got the same error after running the main Makefile. I built only the misc-modules dir with the Makefile in it and it worked. Apparently, the problem lies inside misc-progs.
First kernel I tried with (Raspberri Pi 4B):

I know aarch64 is not a "standard" kernel, but I would be great to run all the examples in a cheap computer.
Thank you.
