From 44f89c38dc72e042d8190f4ca15b26abdb7e69b4 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Sun, 9 Nov 2014 11:21:21 +0100 Subject: [PATCH] libv4l: fix utilities build with older glibc versions Fixes: http://autobuild.buildroot.net/results/9af/9af37fbf344b63b60e59ccac21e010cdf0ea219e/ http://autobuild.buildroot.net/results/bbd/bbd34d5378354e9db7822eaae8d3c4a75a67ac23/ http://autobuild.buildroot.net/results/ebb/ebbaa70e1a277162ba53c7bde8335ee998486703/ http://autobuild.buildroot.net/results/2c1/2c11f4dbb7cfadcfc6fbc267679b2b4eab867221/ And many more. The utilities use clock_gettime(), which was provided in librt in glibc < 2.17, so ensure we link against -lrt.
