编译的时候 error: 'auto' type specifier is a C++11 extension 是什么意思

bash-3.2$ make package install

Making all for tweak WeChatRedEnvelop…

choose.mm:114:10: error: ‘auto’ type specifier is a C++11 extension [-Werror,-Wc++11-extensions]
for (auto iter = choice.result_.begin(); iter != choice.result_.end(); iter++) {
^

意思就是auto是C++11才有的

啥玩意儿?现在微信抢红包要用C++11了? 我老了?
