From 6ab2b762befd192b90704c5c7898f5abf8ebb387 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sat, 28 Mar 2015 11:30:30 +0100 Subject: [PATCH] perf build: Disable libbabeltrace check by default Disabling libbabeltrace check by default and replacing the NO_LIBBABELTRACE make variable with LIBBABELTRACE. Users wanting the libbabeltrace feature need to build via: $ make LIBBABELTRACE=1 The reason for this is that the libababeltrace interface we use (version 1.3) hasn't been packaged/released yet, thus the failing feature check only slows down build and confuses other (non CTF) developers.
