Can't compile a *.cpp file with SFML using g++ on Windows

Question

I'm trying to compile a *.cpp file:

#include <SFML/Graphics.hpp>

using namespace sf;

int main()
{
    
    RenderWindow window(VideoMode(400, 400), L"New project", Style::Default);
    
    window.setVerticalSyncEnabled(true);
       
    CircleShape shape(100.f,3); 
    shape.setPosition(100, 100);           
    shape.setFillColor(Color::Magenta);
        
    while (window.isOpen())
    {
        Event event;
        while (window.pollEvent(event))
        {
            if (event.type == Event::Closed)
                window.close();
        }
        
        window.clear(Color::Blue);
        window.draw(shape);
        window.display();
    }
    return 0;
}

I put g++ Durak.cpp -o output.exe -I"C:\Users\dalvo\IT\SFML (MinGW)\SFML-3.0.0\include" -L"C:\Users\dalvo\IT\SFML (MinGW)\SFML-3.0.0\lib" -lsfml-graphics -lsfml-window -lsfml-system in the console, but get errors:

My versions are as follows: g++ (Rev3, Built by MSYS2 project) 13.2.0; SFML-3.0.0. The line of a command promt's text I asked from ChatGpt. The code I copy-pasted from a website with a guide: https://habr.com/ru/articles/703500/. Others use this code successfully but I don't. Please help me, I've been working on this problem for a several days (want to quit programming already...)

You're reading a tutorial for SFML 2.6, while attempting to use SFML 3.0, which is not backwards compatible. Either download the correct version of the library, or find a tutorial for 3.0. — Some programmer dude

Don't quit but honestly learn programming with something easier than SFML. The best way to learn programming is to read about the language and then attempt to write your own code (or do the exercises). Copying code you don't understand from a website does not teach you very much. — john

I switched to SFML-2.6.2, but now I get undefined reference to `__imp__ZNK2sf10WindowBase6isOpenEv' collect2.exe: error: ld returned 1 exit status. There're much more "undefined references", but I left only 1 just for example. (Tried compiling both VideoMode({400, 400}) and VideoMode(400, 400). The same errors) — dalvol.amsi

I recommend sticking with SFML3 if you are making a new project. Just look at the errors you get and look-up the SFML3 documentation, like the one for sf::Event which shows how the loop is done in SFML3. The demangled name for the function you mentioned is sf::WindowBase::isOpen() const. Perhaps you didn't link with the library containing that. — Ted Lyngmo

Since you are using SFML3, you need to make some changes. Most functions that previously had overloads for taking height and width separately now have a constructor or member function taking a sf::Vector2u, sf::Vector2f or similar, like void CircleShape::setPosition (Vector2f position)

There's also a Migration to SFML3 guide. Just enter VideoMode in the search box and it will show you how to make the call properly in SFML3.

Your program with the issues fixed:

#include <SFML/Graphics.hpp>

using namespace sf;

int main() {
    RenderWindow window(VideoMode({400, 400}), L"New project", Style::Default);
    //                            ^        ^

    window.setVerticalSyncEnabled(true);

    CircleShape shape(100.f, 3);
    // getGeometricCenter() is new in SFML3. 
    // Set origin in the middle of the shape:
    shape.setOrigin(shape.getGeometricCenter());
    shape.setPosition({200, 200});               // center of window
    //                ^        ^
    shape.setFillColor(Color::Magenta);

    while(window.isOpen()) {
        while(auto event = window.pollEvent()) { // polling in SFML3
            if(event->is<sf::Event::Closed>()) {
                window.close();
            } else if(auto keyPressed = event->getIf<sf::Event::KeyPressed>()) {
                if(keyPressed->scancode == sf::Keyboard::Scancode::Escape)
                    window.close();
            }
        }

        window.clear(Color::Blue);
        window.draw(shape);
        window.display();
        shape.rotate(degrees(1.0f)); // rotate takes an sf::Angle in SFML3
    }
}
