修改
我找到了http://llvm.org/docs/GettingStartedVS.html
因此，clang无法解析包含的C ++标准库 使用Visual Studio，也不是Windows Platform SDK的一部分。
因此，如果Visual Studio标头不支持C ++，我还应该编写错误报告吗？
问：
我从http://llvm.org/builds/安装了clang visual studio工具链。 使用VS2013，编译任何c ++标头时会出现几个错误。 例如：
#include <memory>
int main()
{
return 0;
}
这些错误似乎与microsofts c ++ 14实现有关。 在Visual Studio 2012中不会发生这种情况。 在VS2013中切换到工具链 LLVM-vs2012 也可以正常工作
VS2013 + LLVM-vs2013的错误：

你们有没有重现这个错误？如果是，我会在http://llvm.org/bugs/创建一个bug报告。
