GLFW無法創建窗口：「GLX：無法創建上下文：GLXBadFBConfig」

Question

我試圖在我的Debian Stretch系統中創建一個glfw窗口。

的代碼初始化GLFW：

// Initialize GLFW 
void initGLFW() 
{ 
    if (!glfwInit()) 
    { 
     exit(EXIT_FAILURE); 
    } 

    glfwSetErrorCallback(errorCallback); 
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4); 
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0); 
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_FALSE); 
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); 
    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE); 
    glfwWindowHint(GLFW_OPENGL_DEBUG_CONTEXT, GL_TRUE); 

    window = glfwCreateWindow(WINDOW_WIDTH, WINDOW_HEIGHT, "GLSL4.3 + GLM + VBO + VAO", NULL, NULL); 
    if (!window) 
    { 
     fprintf(stderr, "Failed to open GLFW window.\n"); 
     glfwTerminate(); 
     //system("pause"); 
     exit(EXIT_FAILURE); 
    } 
} 

當我運行的可執行文件，我得到上面的消息。爲什麼？

GLX: Failed to create context: GLXBadFBConfig 
Failed to open GLFW window. 

與LIBGL_DEBUG=verbose運行我得到這個

libGL: Can't open configuration file /home/rafael/.drirc: No such file or directory. 
libGL: pci id for fd 5: 8086:0a16, driver i965 
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/i965_dri.so 
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/i965_dri.so 
libGL: Can't open configuration file /home/rafael/.drirc: No such file or directory. 
libGL: Using DRI3 for screen 0 

一些有用的相關信息：

$ lspci | grep VGA

$ glxinfo | grep version

OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.2 
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 

的initGLFW功能從主調用的第一個函數。

您要創建一個OpenGL 4.0核心配置方面：

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4); 
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0); 
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); 

你的驅動器/ OpenGL實現最多隻支持3.3：

OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.2.2 
Max core profile version: 3.3 

梅薩11.2.2 could support的OpenGL 4.1，但只有在某些驅動程序上（來自發行說明11.0.0）：

radeonsi，nvc0上的OpenGL 4.1

梅薩12.0.0 seems to support的OpenGL 4.3 i965的：

的OpenGL 4.3 nvc0，radeonsi，i965的（Gen8 +）

的解決將是更新您的顯卡，Mesa3D或者創建一個3.3上下文來代替：

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); 
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
