Hello everybody, new to SFML  (using Linux ubuntu(
feeling hopeless, tried everything i could think of nothing works:(
can't run codes, i have installed the engine as explained and  seen the green circle , still nothing work

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

i try to run this code but get this error:
