标题: 编译出错：Undefined symbols std::_List_node_base::hook
编译SDK包里面你们提供的源代码工程没有问题，但是编译自己的工程就出错，编译不通过，出错信息下问题：

Undefined symbols for architecture i386:
  "std::_List_node_base::hook(std::_List_node_base*)", referenced from:
      CControlCenter::LeaveRoom(int) in libanychatcore.a(ControlCenter.o)

      CControlCenter::RegisterBitrateStatistItem(unsigned int, unsigned int, unsigned int) in libanychatcore.a(ControlCenter.o)

      ...

怎么办？

您好，根据您提供的信息判断编译已经通过，是在链接（Link）过程中出错，建议通过如下两个步骤来解决：
1、Build Settings-->Apple LLVM 5.1 - Language - C++ --> C++ Standard Library，设置为：libstdc++(GNU C++ standard library)

然后Clean工程，然后重新Build，看是否可以成功。

2、Build Phases --> Link Binary With Libraries里面增加库：libstdc++.dylib

Clean工程，然后重新Build，应该可以Build成功。

如果按上面的方法设置，问题依然存在，则可尝试：在“Project-->Build Phases-->Link Binary With Libraryes”里面添加库“libstdc++.6.dylib”，如下图所示：
