From 1ffc27173576589191b037d111ecb59d94631de0 Mon Sep 17 00:00:00 2001 From: Phil Blundell Date: Thu, 14 Nov 2013 14:41:21 +0000 Subject: boost: Add patch to avoid undefined references to boost::atomic::lockpool::get_lock_for() Boost::thread uses functions from boost::atomic but doesn't actually link with libboost_atomic. This works fine on platforms where BOOST_ATOMIC_FLAG_LOCK_FREE is true but will lead to undefined symbol references otherwise. Fix this by applying a patch from the upstream bug tracker to add the missing library linkage.
