From 44dcf3ec02b5127378fc6569cfa69d251c2973e7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=B6rg=20Krause?= Date: Wed, 30 Mar 2016 22:22:37 +0200 Subject: [PATCH] libwebsockets: fix build with nothread toolchains MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit >From upstream changelog: > If LWS_MAX_SMP=1, then there is no code related to pthreads compiled in the library. If more than 1, a small amount of pthread mutex code is built into the library. Set LWS_MAX_SMP=1 for toolchains without thread support, otherwise leave it unset so upstreams CMakeLists.txt will take care of it.
