我试图用Clang在Fedora 20上编译简单的hello world,我得到以下输出:

d.cpp:1:10:致命错误:找不到'iostream'文件

#include <iostream>

我不知道如何解决它.

我编写了以下简单的 C++ 程序：

#include <iostream>

using namespace std;

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

当我用 g++ 编译它时，它工作得很好。当我尝试使用 Clang++ 进行编译时，出现以下错误：

main.cpp:1:10: fatal error: 'iostream' file not found
#include <iostream>
         ^~~~~~~~~~
1 error generated.

使用-v参数运行，我看到以下内容：

分别查看这些文件夹，我发现在/usr/bin/../lib/gcc/x86_64-linux-gnu/8/../../../../include/c++（或更简洁地说，在/usr/include/c++ …
