在终端运行 C++ 程序

Question

I'm trying to run this simple C++ code in Sublime Text on Terminal but it's not exactly working...

#include <iostream>
using namespace std;

int main() {

    cout << "Hello world!" << endl;
    return 0;

}

I'm getting this message instead:

"hello_world2.cpp:1:10: fatal error: 'iostream' file not found"

How can I fix this?

Answer 1

You most probably are missing development headers for your C++ standard library.

You didn't say anything about your environment, but if you were on Windows on Mac you would for sure get these together with your compiler, so let's assume Linux.

• You need to install libstdc++-devel package or equivalent ( libstdc++-4.8-dev etc.)

Answer 2

In terminal (make sure you're in correct directory), type g++ {{ file_name }} . This command will generate an output file named with 'a.exe' and you have to just execute that. Type .\a.exe to execute that output file. enter image description here
