#include <iostream>
using namespace std;

int main() {

    cout << "Hello, World!" << endl;
    return 0;
    
}

i dont know what i should try

`gcc` is a C compiler, call `g++` for C++. Also, the most important error is the first one, not the last one. — HolyBlackCat, Aug 19 '23 at 09:53
If you search for `collect2.exe: error: ld returned 1 exit status` you would get several thousands of hits. If you then add the terms `gcc` and `c++` you would quite easily have found the answer to your problem. — Some programmer dude, Aug 19 '23 at 10:04

If you use gcc for C++ code, you have to manually link against the C++ standard library. g++, the c++ compiler however, automatically links against the C++ standard library, so change:

gcc main.cpp -o myProgram

to

g++ main.cpp -o myProgram
