From 7aec51cbf0646cc15d719b08caea931576dc7f2a Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 12 Aug 2015 15:48:37 -0700 Subject: perf tools: Support static linking with libdw The Fedora 22 version of libdw requires a couple of extra libraries to link. With a dynamic link the dependencies are pulled in automatically, but this doesn't work for static linking. Add the needed libraries explicitely to the feature probe and the Makefile. v2: Explicitly check for static linking and only add the dependencies when -static is set. This is to avoid regressions on Arnaldo's system.
