Window Crashes Immediately.

[taserman21]

I am trying to learn SFML and tried the first code it shows on the website:

#include <SFML/Graphics.hpp>

int main()
{
        sf::RenderWindow window(sf::VideoMode(1366, 768), "Hello World!");
        sf::CircleShape shape(100.f);
        shape.setFillColor(sf::Color::Blue);

        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;
        }
}
 

After compiling it with g++ -o Hello_World Hello_World.cpp I get:

*** Error in `./Hello_World': free(): invalid pointer: 0x0000000000dfadc8 ***
Aborted (core dumped)
 

Please help me.

You're not being very clear. Is the error from the compiler, or is the error from the program?

Also, don't return 0; in the loop. That will close the window (and application).

It comes from the program and I did try to run it without return 0; and that didn't work either.

It really sounds like you are mixing either debug/release versions or using a copy of SFML that wasn't compiled for the compiler you have. Could you please tell us what compiler version you are using and what SFML package from the website you downloaded?
