「段錯誤：11」利用廢棄和OpenGL

當

/**

import std.stdio;

import derelict.sdl.macinit.SDLMain; 
import derelict.opengl.gl; 

pragma(lib, "/usr/local/src/Derelict2/lib/libDerelictUtil.a"); 
pragma(lib, "/usr/local/src/Derelict2/lib/libDerelictSDL.a"); 
pragma(lib, "/usr/local/src/Derelict2/lib/libDerelictGL.a"); 

int main(string[] args) { 

    // Load Derelict 
    writeln("Loading SDL..."); 
    DerelictSDL.load(); 

    // Initialise SDL 
    if(SDL_Init(SDL_INIT_EVERYTHING) == -1) { 
     throw new Exception("SDL initialization failed"); 
    } 

    // Enable Double Buffering 
    SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1); 

    // Set up the screen 
    SDL_Surface* screen = SDL_SetVideoMode(640, 480, 0, SDL_OPENGL); 
    if (screen == null) { 
     throw new Exception("Screen is null"); 
    } 
    SDL_WM_SetCaption("Simple", "Simple"); 

    // Print OpenGL and GLSL version 
    writeln("Version Info"); 
    writeln("OpenGL:\t", glGetString(GL_VERSION)); 
    writeln("GLSL:\t", glGetString(GL_SHADING_LANGUAGE_VERSION)); 

    // Execute frame update 
    SDL_GL_SwapBuffers(); 

    // Quit SDL; SDL_Quit() takes care of freeing the screen surface 
    writeln("Quitting SDL..."); 
    SDL_Quit(); 

    writeln("Bye!"); 
    return 0; 
}

它編譯罰款，但是當我嘗試運行它，我得到：

$ ./simple 
Loading SDL... 
Version Info 
Segmentation fault: 11

這裏的線程輸出：

現在，如果我嘗試編譯都在32位模式遺棄和simple.d（-m32 ）我得到這樣的輸出，而不是：

$ ./simple 
Loading SDL... 
Version Info 
Bus error: 10

我已經試過像glClearColor()其他gl...功能和它們產生相同的結果。

你沒有加載GL函數指針。

DerelictGL.load();
