From c79ed23df5090294a81fd66f67632e4535fb3164 Mon Sep 17 00:00:00 2001 From: Francis Deslauriers Date: Mon, 28 Nov 2016 10:52:17 -0500 Subject: [PATCH] configure: fix LTTng UST tracing backend detection The detection program needs to be linked with -ldl to build succesfully with recent versions of LTTng-UST. We also need to add -ldl to the libs required to build the LTTng-UST backend (lttng_ust_libs).
