Windows上的Msys2和Clang：找不到iostream文件

Question

我按照本教程（here）获取了Clang在Windows上的工作。我选择与msys2结合安装clang的路径。

以下的所有指令后，我写了简单的程序： 铛++ Helloworld.cpp HelloWorld.exe的-o -std = C++ 14

我得到的错误：

#include <iostream> 
using namespace std; 

int main() 
{ 
cout<<"Hello, World!\n"; 
return 0; 
} 

与编译后：

*Helloworld.cpp:2:10: fatal error: 'iostream' file not found,

1 error generated.*

添加-v在命令行中我得到：

如何让系统找到的iostream？我读了一些关于，你必须指向clang/lib/Frontend/InitHeaderSearch.cpp中的mingw头文件。我在我的电脑上找不到InitHeaderSearch.cpp文件。

谢谢你的帮助。

由于在构建脚本一些依赖丢失的错误。

安装gcc包（3234位的mingw-w64-i686-gcc和64位的mingw-w64-x86_64-gcc）会将它们拉出来。
