Can't compile a *.cpp file with SFML using g++ on Windows
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:
main.cpp: In function 'int main()':

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...)

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
}
}
