Requiring the full kernel tree to be available at build time will make this unbuildable on distros that still use makefiles, like RHEL and SUSE. At least on Debian and Ubuntu, the kernel headers packages distributed do not include the full kernel tree, only the headers, so there's no tools/lib or tools/include. Like other dependencies, this should assume they are installed as regular libraries, eg: CFLAGS +=3D $(shell command -v pkg-config > /dev/null 2>&1 && pkg-config --= cflags libbpf || echo "-I/usr/include/bpf") > +CFLAGS +=3D $(WERROR_FLAGS) > +LDLIBS +=3D -lrte_eal -lrte_mbuf -lrte_mempool -lrte_ring > +LDLIBS +=3D -lrte_ethdev -lrte_net -lrte_kvargs > +LDLIBS +=3D -lrte_bus_vdev > +LDLIBS +=3D -lbpf LDLIBS +=3D $(shell command -v pkg-config > /dev/null 2>&1 && pkg-config --= libs libbpf || echo "-lbpf") --=20 Kind regards, Luca Boccassi
