IOS-VLC静态库使用时报错

编译VLC静态库通过了，并且在官方的源码中也能正常使用此静态库

Undefined symbols for architecture armv7:

      libebml::CRTError::CRTError(std::string const&, int) in libMobileVLCKit.a(StdIOCallback.o)

解决方案:把C language Dialect 设置为Compoler Default 把 Compolile Source As 设置为According to File Type 最重要的要把 C++ Standard Library 设置为 libstdc ++ 最后一步把appdelegate的.m文件后缀改为.mm 问题解决 成功走起 。。
