c++ - 需要帮助在 Windows 上正确设置 CLANG

Question

我需要一些帮助才能在 Windows 上正确设置 clang。

我安装了 Visual Studios 2015。和 Windows SDK。 我最近安装了 Clang，并通过它运行了一个非常基本的 hello world 以确保它正常工作。它给了我一个我无法理解的错误。

Visual Studios 会处理得很好。

这是我从 clang 收到的错误输出:

Microsoft Windows [Version 10.0.14393]

C:\Users\Leo>cd C:\Users\Leo\Desktop\Sandbox

C:\Users\Leo\Desktop\Sandbox>clang++ hello.cpp
In file include d from hello.cpp:1:

  'corecrt.h' file not found
#include <corecrt.h>
         ^

hello.cpp 中的第 1 行只是:

#include <iostream>

所以这个错误对我来说没有意义。

在命令提示符下键入 echo %INCLUDE%。查看您的 INCLUDE 路径。

检查以确保您的 INCLUDE 环境变量未设置为包含 Visual Studio 路径的路径。可能还需要对 LIB 环境变量执行相同的操作。
