Thanks again! o/

You could always try to compile SFML from the latest GitHub master, or the very latest soon-to-be-merged gl_dev branch. If you haven't already tried, maybe compiling the 2.2 source yourself might already fix the problem.

Thanks a lot! 

I first tried to compile with cmake the master from git, and it apparently solved the situation for drawing stuff, but the problem remained for texture loading. BUT when I tried with the g_dev_new branch it worked. It's good to see that the features that they're adding are actually helping us. I would ask for a couple more days to confirm if everything is really ok, so we can consider this as solved.

Yeah I don't know well what to do  ... I have the following:

Code: [Select]

glxinfo | grep OpenGL

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 10.3.2
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 10.3.2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.0
OpenGL ES profile extensions:

As far as I know, 10.3.2 it's a pretty recent version...

This is just a wild guess, but are you completely sure that window.display() is being called at the end of the render loop? I notice when I test the code you posted (on Ubuntu Linux) it creates a sort of screenshot effect in the window when window.display() is commented out. Otherwise it runs fine. Did you try the SFML-Linux tutorial and just using a text editor + command line?

Yes, I have similar results. But the screenshot result appears even with the window.display(). If I comment the window.draw(), thought, the window do goes black.

I've followed precisely this tutorial: http://www.sfml-dev.org/tutorials/2.0/start-linux.php

Compiling with g++ in the terminal, linking to my non-default folder where I built it, doesn't make a difference

Notice that the code I posted is exactly the one from the same tutorial.

Hi! It's really for any code, but we can use the Hello World of the SFML tutorials as example:

#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;
}

General / SFML not drawing anything on window [Linux, Eclipse]

Hello guys.

This is my first time with SFML, I've installed the 2.2 version from the pre-compiled SDK and configured Eclipse for using it. My specs are:

- Linux Ubuntu (Gnome Version) 64bits, Kernel 3.16
- GCC 4.9.1
- Eclipse Luna
- Intel Core i7-4510U

What happens is that, whenever I try to run it, the window appears, with the correct dimensions, but the content is random. In a few times (usually the first time I compile it after a reboot), the image is drawn. But almost always what happens is that the window is filled with a sort of screenshot of the app running right under it. In other words, it's not rendering properly

I tried this with the simple hello world with green circle, and also with more complex stuff, like loading a texture. I suppose it is something related to my graphics card driver, but I'm not sure because I have projects on OpenGL rendering without problems.

Any tip for what should I do?

Sry for any english mistakes.
