From 46dad054a19297af65c417c97cb920aa5bdf7e8c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 7 Mar 2016 18:48:45 -0300 Subject: [PATCH] perf jitdump: DWARF is also needed While building on a Docker container for ubuntu and installing package by package one ends up with: MKDIR /tmp/build/util/ CC /tmp/build/util/genelf.o util/genelf.c:22:19: fatal error: dwarf.h: No such file or directory #include ^ compilation terminated. mv: cannot stat '/tmp/build/util/.genelf.o.tmp': No such file or directory Because the jitdump code needs the DWARF related development packages to be installed. So make it dependent on that so that the build can succeed without jitdump support.
