From d25ed5d9fad98fd36ffca0bb5c3a0761a11e3f3c Mon Sep 17 00:00:00 2001 From: Soramichi AKIYAMA Date: Tue, 17 Jan 2017 00:22:37 +0900 Subject: [PATCH] perf tools: Move two variables usied in libperf from perf.c The use_browser and perf_version_string variables are both declared in perf.c but they are also referenced by other functions of libperf.a. Therefore a user linking an own main() with libperf.a must declare those two variables in their files even if the files never use the browser or the version information. This patch fixes this issue by moving use_browser and perf_version_string out of perf.c to some other files.
