sigsev qhen quitting after calling Window::create
« on: September 07, 2011, 03:18:54 pm »
I've used SFML 2.x (fetched and compiled today)

to reproduce compile the following code, run it.
press seval times (about 10 times) Tab and then quit with esc.

There are no errors on my PC (GTX 470, Ubuntu x64), but on my notebook (intel GM45, Ubuntu x64) this gets a sigsev.

Code: [Select]

#include <GL/glew.h>
#include <SFML/Window.hpp>
#include <iostream>

void init_states()
  // Set color and depth clear value
  glClearColor(0.f, 0.f, 0.f, 0.f);

  // Enable Z-buffer read and write

  // Setup a perspective projection
  gluPerspective(90.f, 1.f, 1.f, 500.f);

int main()
    sf::ContextSettings Settings;
    Settings.DepthBits         = 32; // Request a 24 bits depth buffer
    Settings.StencilBits       = 8;  // Request a 8 bits stencil buffer
    Settings.AntialiasingLevel = 4;  // Request 2 levels of antialiasing
    sf::Window App(sf::VideoMode(800, 600, 32), "SFML OpenGL", sf::Style::Close, Settings);
    // Create a clock for me
    sf::Clock Clock;


    // Start game loop
    while (App.IsOpened())
        // Process events
        sf::Event Event;
        while (App.PollEvent(Event))
            // Close window : exit
            if (Event.Type == sf::Event::Closed)

            // Escape key : exit
            if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Keyboard::Escape))
            if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Keyboard::Tab))
              App.Create(sf::VideoMode(800, 600, 32), "SFML OpenGL", sf::Style::Close);

            // Resize event : adjust viewport
            if (Event.Type == sf::Event::Resized)
                glViewport(0, 0, Event.Size.Width, Event.Size.Height);

        // Set the active window before using OpenGL commands
        // It's useless here because active window is always the same,
        // but don't forget it if you use multiple windows or controls

        // Clear color and depth buffer

        // Apply some transformations
        glTranslatef(0.f, 0.f, -200.f);
        //a += 0.1f;
        glRotatef(Clock.GetElapsedTime() * 0.001f * 50.f, 1.f, 0.f, 0.f);
        glRotatef(Clock.GetElapsedTime() * 0.001f * 30.f, 0.f, 1.f, 0.f);
        glRotatef(Clock.GetElapsedTime() * 0.001f * 90.f, 0.f, 0.f, 1.f);

        // Draw a cube

            glVertex3f(-50.f, -50.f, -50.f);
            glVertex3f(-50.f,  50.f, -50.f);
            glVertex3f( 50.f,  50.f, -50.f);
            glVertex3f( 50.f, -50.f, -50.f);

            glVertex3f(-50.f, -50.f, 50.f);
            glVertex3f(-50.f,  50.f, 50.f);
            glVertex3f( 50.f,  50.f, 50.f);
            glVertex3f( 50.f, -50.f, 50.f);

            glVertex3f(-50.f, -50.f, -50.f);
            glVertex3f(-50.f,  50.f, -50.f);
            glVertex3f(-50.f,  50.f,  50.f);
            glVertex3f(-50.f, -50.f,  50.f);

            glVertex3f(50.f, -50.f, -50.f);
            glVertex3f(50.f,  50.f, -50.f);
            glVertex3f(50.f,  50.f,  50.f);
            glVertex3f(50.f, -50.f,  50.f);

            glVertex3f(-50.f, -50.f,  50.f);
            glVertex3f(-50.f, -50.f, -50.f);
            glVertex3f( 50.f, -50.f, -50.f);
            glVertex3f( 50.f, -50.f,  50.f);

            glVertex3f(-50.f, 50.f,  50.f);
            glVertex3f(-50.f, 50.f, -50.f);
            glVertex3f( 50.f, 50.f, -50.f);
            glVertex3f( 50.f, 50.f,  50.f);

        static int i=0;
        std::cout<<"rendered frame "<<i++<<"\n";

        // Finally, display rendered frame on screen

    return EXIT_SUCCESS;
