Tutorial Question

[thyagobr]

Hi guys.

I'm starting with SFML now, and installed it following the SFML with Linux (http://sfml-dev.org/tutorials/2.1/start-linux.php) tutorial.

Everything went fine, but the test code opened the window without the green circle expected:

#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;
}

And compiled with:

g++ -c graphics.cpp
g++ graphics.o -o graphs -lsfml-graphics -lsfml-window -lsfml-system

Did anyone ever experienced this and could help me with the issue?
Thanks.

What graphics driver are you using? Do you get any messages in the terminal when running the test app?

Hi eXpl0it3r, thanks for helping =]

My graphics card:

01:00.0 VGA compatible controller: NVIDIA Corporation GF114 [GeForce GTX 560 Ti] (rev a1) (prog-if 00 [VGA controller])
        Subsystem: eVga.com. Corp. Device 1563
        Flags: bus master, fast devsel, latency 0, IRQ 45
        Memory at f4000000 (32-bit, non-prefetchable) [size=32M]
        Memory at e0000000 (64-bit, prefetchable) [size=128M]
        Memory at e8000000 (64-bit, prefetchable) [size=64M]
        I/O ports at e000 [size=128]
        [virtual] Expansion ROM at f6000000 [disabled] [size=512K]
        Capabilities: <access denied>
        Kernel driver in use: nvidia

And yes, sorry, I should have mentioned this =]

I get a message when I run the executable, only:

./graphs: Symbol `_ZN2sf12RenderStates7DefaultE' has different size in shared object, consider re-linking

iirc, that means you have multiple versions of sfml installed, and it's using a different one at runtime than it used when linking. I'd double check for an older version of sfml and remove it.

[thyagobr]

Yes, you're right.

It had to do with the fact that I tried to install from source before, had trouble with libs and then used apt-get. I purged libsfml-dev, then installed again, and the circle is up there.

Sorry for not having tried this before, but hope it helps other beginners who might make the same mistake =]

Thanks for the help!

It's good to know that you now have SFML working and can enjoy its wonders! 
We look forward to hearing about what you create
