Message-Id: <20171219.152203.371422797348974116.davem@davemloft.net> Date: Tue, 19 Dec 2017 15:22:03 -0500 (EST) From: David Miller <davem@...emloft.net> To: daniel@...earbox.net CC: netdev@...r.kernel.org Subject: [PATCH bpf]: Fix tools and testing build. I'm getting various build failures on sparc64. The key is usually that the userland tools get built 32-bit. 1) clock_gettime() is in librt, so that must be added to the link libraries. 2) "sizeof(x)" must be printed with "%Z" printf prefix.
