我在Mac OS 10.11.1上使用cocos2d-x 2.2.6开发了一个项目，X-code 7.1。所有配置均为默认值。我需要包含<thread>，<mutex>等标题文件，当我构建项目时出现错误，＆＃34;＆＃39; thread＆＃39;找不到文件＆＃34;。我搜索了这个错误然后我意识到我必须更新我的X代码配置以支持c ++ 11.我修改了一些配置如下：
TARGET->Build Settings->Apple LLVM 7.0 - Language - C++
C++ Language Dialect => c++11[-std=c++11]
C++ Standard Library => c++11[-std=c++11]
[the configuration I modified][1]
I build the project after clean. then I got a lot of errors.
[errors][2]
Errors like bellow :
"std::string::operator=(std::string const&)", referenced from:
cocos2d::CCLabelTTF::_prepareTextDefinition(bool) in libcocos2dx.a(CCLabelTTF.o)
"std::string::operator[](unsigned long)", referenced from:
"std::string::operator+=(char const*)", referenced from:
"std::string::operator+=(std::string const&)", referenced from:

"std::ios_base::Init::Init()", referenced from:
"std::ios_base::Init::~Init()", referenced from:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
今天我创建了一个全新的项目，我不会改变一个词，项目运行良好。但是当我修改配置时，错误再次出现。
我需要项目支持c ++ 11。我怎样才能解决这个问题 。这几天我一直困扰着这个问题。我想念一些图书馆吗？非常感谢你。我会一直在线。
