Title: Problem with linking graphics.hpp
Post by: lotnik9o on February 23, 2012, 01:35:01 pm

I've a problem to linking this code:

Code: [Select]

int main()
{
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");
   
    // Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
        }

        // Clear the screen (fill it with black color)
        App.Clear();

        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}

and I got this errors:

Earlier I linking my programs with window.hpp and there were none problems. Can someone help me?

You must link (as in "add to the linker settings", not just include the header) to the sfml-window library, the same way you did with sfml-system.

Same with sfml-graphics if you use the graphics module (Graphics.hpp).

Thank you for answer. I did so with sfml-graphics, but the problem is still the same, only with the graphics module.

I had none problems to linking when I use the system or window module.

You still need sfml-window and sfml-system, sfml-graphics doesn't replace them.
