I want to rebuild libwebsocets,
I fallow this topic: http://carlgira-ot.blogspot.tw/2016/11/websocketserver-cocos2djs-part-1.html
and clone the cocos2d-x 3rd party libs from: https://github.com/cocos2d/cocos2d-x-3rd-party-libs-src
type “./build.sh --platform=mac --libs=websockets” in terminator
I got this error:
/Users/joey/Downloads/cocos2d-x-3rd-party-libs-src-3/contrib/mac-x86_64/websockets/lib/server.c:113:27: error:
use of undeclared identifier ‘SOL_IPV6’
