Windows上的Msys2和Clang：未找到iostream文件 [英] Msys2 and Clang on Windows: iostream file not found

问题描述

我按照本教程(here)让Clang在Windows上运行。我选择了安装clang和msys2的路径。

按照所有说明编写了简单的程序：

#include <iostream>
using namespace std;

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

使用以下命令编译后： Clang++Helloworld.cpp-o Helloworld.exe-std=c++14

我收到错误：

*HelloWorld.cpp：2：10：致命错误：找不到‘iostream’文件，

%1生成错误。*

在我得到的命令行中添加-v：

如何让系统查找iostream？我读到了一些东西，您必须指向clang/lib/Fronend/InitHeaderSearch.cpp中的mingw头文件。我在电脑上找不到InitHeaderSearch.cpp文件。

感谢您的帮助。

Windows 8 Clang 3.9.1

推荐答案

由于生成脚本中的错误，某些依赖项丢失。

安装GCC包(32位mingw-w64-i686-gcc，64位mingw-w64-x86_64-gcc)拉取。
