From bd0419e2a5a9fd9396cb7dc69044f961f52e19f0 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 5 Apr 2016 11:33:41 -0300 Subject: perf probe: Check if dwarf_getlocations() is available If not, tell the user that: config/Makefile:273: Old libdw.h, finding variables at given 'perf probe' point will not work, install elfutils-devel/libdw-dev >= 0.157 And return -ENOTSUPP in die_get_var_range(), failing features that need it, like the one pointed out above. This fixes the build on older systems, such as Ubuntu 12.04.5.
