我正在尝试在我的Debian Stretch系统中创建一个glfw窗口。
初始化glfw的代码:
// 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);
}
}
当我运行可执行文件时,我得到上面的消息。为什么?
GLX: Failed to create context: GLXBadFBConfig
Failed to open GLFW window.

一些有用的信息:
$ lspci | grep VGA

该initGLFW
函数是从main调用的第一个函数。
您正在尝试创建OpenGL 4.0 Core配置文件上下文:
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
您的驱动程序/ OpenGL实现最多仅支持3.3:
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.2.2
Max core profile version: 3.3
Mesa 11.2.2可以支持OpenGL 4.1,但仅支持某些驱动程序(来自11.0.0的发行说明):
radeonsi,nvc0上的OpenGL 4.1
Mesa 12.0.0似乎在i965上支持OpenGL 4.3:
nvc0,radeonsi,i965(Gen8 +)上的OpenGL 4.3
解决方法是更新您的显卡,Mesa3D或创建3.3上下文:
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
