我正在尝试使用OpenGL 3.3编译我的应用程序。我在线搜索了我的显卡,它最多支持4.4。
这是glxinfo |的回归grep OpenGL
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 520 (Skylake GT2)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.3
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 17.2.3
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 17.2.3
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:
我告诉GLFW使用主要版本3次要版本3
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
并使用核心配置文件:
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
我很高兴指向版本3.3和核心配置文件:
python -m glad --api "gl=3.3" --generator c --out-path ./output --profile core --spec gl
但是当我打电话时
glGetString(GL_VERSION)
我回来了
3.0 Mesa 17.2.3
我不能为我的生活找出我所缺少的东西。
运行此代码的部分
{
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_FLOATING, GL_TRUE);
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
if (!glfwInit()) {
std::cout << "glfw not inited" << std::endl;
}
glfwSetErrorCallback(error_callback);
m_game_window = glfwCreateWindow(800, 600, "window", NULL, NULL);
if (!m_game_window) {
std::cout << "window creation failed" << std::endl;
glfwTerminate();
//crash
}
glfwMakeContextCurrent(m_game_window);
gladLoadGLLoader((GLADloadproc) glfwGetProcAddress);
glViewport(0, 0, 800, 600);
char *version = (char*)glGetString(GL_VERSION);
std::cout << version;
}
答案 0 :(得分:2)
您不得在glfwInit()
之前调用任何GLFW函数。在您的情况下,窗口提示将由glfwInit()
完全重置。
