Hello,
This post is about Linux free radeon driver issues.
My test computer running on :
System : openSUSE 11.4 (x86_64)
GPU : HD 5770
2D Driver : radeon
3D Driver : R600 classic (7.10.2)
This code causes segfault at the end, when window is destroyed.
int main(){
sf::RenderWindow window(sf::VideoMode(800, 600, 32), "test");
bool running = true;
while (running)
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed) running = false;
}
window.clear();
window.display();
}
}
If I remove window.clear() there is no segfault. Segfault happen when XCloseDisplay is called and when glClear(GL_COLOR_BUFFER_BIT) has been used before.
This code causes PC crash :
int main(){
sf::RenderWindow window(sf::VideoMode(800, 600, 32), "test");
bool running = true;
sf::RenderTexture texture;
if (!texture.create(500, 500)){
std::cout<<"failed to create render texture"<<std::endl;
return -1;
}
while (running)
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed) running = false;
}
window.clear();
texture.clear(sf::Color::Red);
texture.display();
window.display();
}
}
If I remove texture.clear it runs.
I have tested both code in a similar configuration with fglrx driver (not free) and it was OK.
I thought it could be useful for people who have these problems to know these are actually driver issues.
Maybe it could be fix in the SFML but I am not really optimist about that.
Edit: I forgot to said that I use Git version.
