Run a debugger, find the origin of the segfault and provide the call stack.

Also provide your full build command.

This is a runtime error(not compile-time), and this problem is related with OpenGL context creation in SFML.
Also, the segment fault was appeared at glGenBuffers().

General / Having a problem with glGenBuffers(...)

« on: December 20, 2014, 10:07:20 am »

Hello. I was just trying to do some kind of GPGPU Computing with OpenGL and OpenCL(you don't have to know about OpenCL),
and I created a VBO(vertex buffer object) before creating a window.

GLuint vbo;
glGenBuffers(1,&vbo);
 

But there was a segmentation fault and the program throwed an error.
So, I tried to create a VBO after creating window, but it doesnt' work neither. It worked only in the 'main loop', and I want to initialize everything before creating the window. What's the problem and how can I solve this?

 

int main()
{
        sf::Context context;//I think this code doesn't related with my problem.
        Fluid fluid;

        cout<<"main() - Window initalized"<<endl;
        sf::RenderWindow window(sf::VideoMode(1080, 720), "SFML works!",sf::Style::Titlebar|sf::Style::Close);

        //initialize something

    // The 'main loop'
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        //draw and update something

    }

    //exit

}
