From 70cb50ea9a7aa0554c3874862192b5ca3b1283d5 Mon Sep 17 00:00:00 2001 From: Ruben Kerkhof Date: Sat, 23 Apr 2016 17:35:39 +0200 Subject: [PATCH] rrdtool plugin: fix thread-safety detection librrd 1.6.0 is now threadsafe and librrd_th is gone. Since there doesn't seem to be a way to detect that librrd is threadsafe, use pkg-config to check for 1.6.0 or newer instead. The logic is now as follows: Check for librrd >= 1.6.0 with pkg-config If not found, look for rrd_update_r in librrd_th. If not found, look for rrd_update in librrd and assume librrd is not thread safe.
