Graphics / Using sf::RenderTexture crashes silently

« on: November 09, 2011, 02:04:28 am »

Hello,

This code prints Hello world but exits with code 1

Code: [Select]

#include <iostream>
#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderTexture renderTexture;
    renderTexture.Create(512, 512);
    renderTexture.Clear();
    //renderTexture.Display();
 
    std::cout << "Hello world!" << std::endl;

    return EXIT_SUCCESS;
}

If I uncomment the line which calls Display of renderTexture, it crashes silently and I get 1 as exited code. And doesn't print Hello world anymore

Code: [Select]

#include <iostream>
#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderTexture renderTexture;
    renderTexture.Create(512, 512);
    renderTexture.Clear();
    renderTexture.Display();
 
    std::cout << "Hello world!" << std::endl;

    return EXIT_SUCCESS;
}

I'm using the lastest version (commit 017ef652f9).
OS: Fedora 16 (64bits)
GC: Nvidia Getforce GT540M

I must add that my computer also has an intel GPU but I'm not aware of how fedora uses them (nvidia and intel gpu).

Can anyone help me?

Audio / AL lib: ALc.c:1420: alcDestroyContext()

« on: November 09, 2011, 01:38:48 am »

Hello,

I get this output

AL lib: ALc.c:1420: alcDestroyContext(): deleting 1 Source(s)
AL lib: ALc.c:1818: alcCloseDevice(): deleting 3 Buffer(s)

when I run this : http://pastebin.com/BuVkHpPP

#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>

int main()
{
    sf::Texture texture;
    texture.LoadFromFile("data/1440x900.jpg");
   
    sf::Sprite sprite(texture);

    sf::Music music;
    music.OpenFromFile("data/nice_music.ogg");
       
    music.Play();

   sf::RenderWindow window(sf::VideoMode(1440, 900), "SFML window"); // ,sf::Style::Fullscreen);
   
    while (window.IsOpened())
    {
        sf::Event event;
        while (window.PollEvent(event))
        {
            if (event.Type == sf::Event::Closed)
                window.Close();
        }

        window.Clear();
        window.Draw(sprite);
        window.Display();
    }

    return EXIT_SUCCESS;
}

I'm using the lastest revision of SFML2 (don't know how to get the number) on Fedora 16 (amd64), no proprietary drivers and my graphic card is Nvidia GT540M.

I must warm you that if I comment this line

window.Draw(sprite);

it works as expected...

Strange, isn't it ?

Thanx for helping!
