Subject: [Buildroot] [PATCH 2/2] boost: context needs C++11
Date: Mon, 20 Aug 2018 18:55:55 +0200	[thread overview]
Message-ID: <20180820165555.20492-2-fontaine.fabrice@gmail.com> (raw)
In-Reply-To: <20180820165555.20492-1-fontaine.fabrice@gmail.com>

Without this flag, mutex is not always correctly detected with gcc 4.x
or 5.x. As a result, boost_thread is wrongly selected by boost_context.

Fixes:

 - http://autobuild.buildroot.net/results/99f1a255b78a973faeb8bf3b94d78efc54426a8b
