I've got it pointed to a locally built kernel built using the config/config.x86_64, and have tried running the vmtest.sh script, and building just the tests via make. I'm using O= to direct it to the out directory for the kernel build. I've been hitting various errors when trying this. Confusingly the error message isn't always the same. Currently from a clean build, it complains about "linux/atomic.h" not found via #include "../../../include/linux/filter.h"'s in various files. Other times it's complained about the various helper functions from bpf_helper_defs.h being unused. I'm not sure if I'm invoking the command wrong, or missing dependencies or something. I got past some earlier issues by updating clang. Any idea what I'm doing wrong?
