The kernel's samples/bpf/ should still builds with LLVM-9 (and lower). Follow instructions in the README.rst file[1]. There are pre-build Debian and Ubuntu packages for LLVM-10 here: https://apt.llvm.org/ > I am just trying to play with basic examples at this point) I suggest you start with the XDP-tutorial[2], it (still) works with older LLVM versions: [2] https://github.com/xdp-project/xdp-tutorial [1] https://github.com/torvalds/linux/blob/master/samples/bpf/README.rst -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
