From 0cc54db1818ad38f400be9f24871f3b7bf09e911 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 14 May 2018 22:35:05 -0700 Subject: samples: bpf: move libbpf from object dependencies to libs Make complains that it doesn't know how to make libbpf.a: scripts/Makefile.host:106: target 'samples/bpf/../../tools/lib/bpf/libbpf.a' doesn't match the target pattern Now that we have it as a dependency of the sources simply add libbpf.a to libraries not objects.
