[MAC OS X] SFML2 & Failed to activate the window's conte

[AdrianM]

I'm trying to figure out what's happening here. I just get a white window with this code(the output should be black). Also looking at the console i see that every frame a message is sent: "Failed to activate the window's context." I'm on an INTEL card here(old i know), so what could be wrong?

Code: [Select]

int main()
{
    // Create the main window
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML OpenGL");

    // Start game loop
    while (window.IsOpened())
    {
        // Process events
        sf::Event event;
        while (window.GetEvent(event))
        {
            // Close window : exit
            if (event.Type == sf::Event::Closed)
                window.Close();

            // Escape key : exit
            if ((event.Type == sf::Event::KeyPressed) && (event.Key.Code == sf::Key::Escape))
                window.Close();
        }
        // Clear the depth buffer & color buffer
        glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);

        // Finally, display the rendered frame on screen
        window.Display();
    }

    return EXIT_SUCCESS;
}

Are you able to run other OpenGL applications on your computer?

[Ceylo]

The reason is much simpler. From SFContext.mm line 87 :

Code: [Select]

bool SFContext::MakeCurrent()
{
    [myContext makeCurrentContext];
}
Hiura forgot the return call. He should be notified about this little mistake .

Is it better now ?

@ Ceylo : thanks a lot !
