From fc67297b16da335d610af2fac96233d51146300a Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 13 Sep 2013 15:27:43 +0900 Subject: perf tools: Separate out GTK codes to libperf-gtk.so Separate out GTK codes to a shared object called libperf-gtk.so. This time only GTK codes are built with -fPIC and libperf remains as is. Now run GTK hist and annotation browser using libdl.
