ARRAY_SIZE is defined in multiple test files. Remove the definitions and include header file for the define instead.
Remove ARRAY_SIZE define and add include bpf_util.h to bring in the define.

It doesn't look like you've built it.

Sorry about that. I built it - I think something is wrong in my env. Build fails complaining about not finding vmlinux - I overlooked that the failure happened before it got to progs.
Error: failed to load BTF from .../vmlinux: No such file or directory
Please make sure that you build vmlinux before you build selftests, BPF selftests use vmlinux to generate vmlinux.h with all kernel types (among other things). So please also make sure that all the setting in selftests/bpf/config were used in your Kconfig.
The problem in my env. is that I don't have CONFIG_DEBUG_INFO_BTF in my config and then don't have the dwarves and llvm-strip on my system. Pains of upgrading.
I am all set now. On the other hand the vmlinux.h is a mess. It has no guards for defines and including stdio.h and this generated vmlinux.h causes all sorts of problems.
