Hi all,

I'm trying to compile and run eBPF programs with BTF(CO-RE). Should I
compile a custom kernel with  CONFIG_DEBUG_INFO_BTF set or is it set in the
current build and I am missing something?

In the current build I can't find "/sys/kernel/btf/vmlinux".

Any help would be appreciated

Thanks

That setting has been enabled in [d97c07c67c][0] and will be part of
alpine 3.18.
