c++ - 使用 clang 编译 C++ 文件时出错

标签 c++ compiler-construction clang

在 linux 环境上构建 CLang 后，我尝试使用 Visual Studio 在 Windows 上构建它。一切顺利，但当我尝试编译这个经典的 Hello World! 程序时

#include <iostream>

int main()
{
   std::cout<<"Hello World!";
}

我有很多错误

但是当我将相同的 Hello World 程序编译为 C 文件时，一切都很顺利。

 #include <stdio.h>

 int main()
 {
     printf("Hello World!");
 }

 C:\Users\SUPER USER\Desktop>clang a.c

 C:\Users\SUPER USER\Desktop>a.out
 Hello World!

这里的实际问题是什么？

最佳答案

似乎 clang 不喜欢包含 VC10 头文件。我会用 VC9 试试。
