4 months ago Have you tried checking khronos.org for docs?They literally have an well-explained example of how to use debugs with glEnable(GL_DEBUG_OUTPUT) oh, by the way enabling debug outputs doesn't mean that you can start debugging straight away, you should still do some work to get these mesages that created by GL_DEBUG_OUTPUT feature.Here is the official docs for OpenGL from Khronos:
https://www.khronos.org/opengl/wiki/Debug_Output
If you need further help, i'll be there.
Edit : Remember learnopengl.com is an old tutorial so it can lack of some new stuff.In learnopengl.com you normally load GLAD like this :
if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress)) { std::cout << "Failed to initialize GLAD" << std::endl; return -1; }
but you can actually do this and save a few lines of code(while sacrificing the error checking) with just this:
gladLoadGL()
So yes learnopengl.com can lack of some modern stuff.You might need to also check for other docs when needed.

Hello, I am a big fan of your tutorials but there is something that I think would be worth changing. I'm talking about debugging. On the web and on YouTube people only show the old OpenGL debugging thing, which is just horrible to use, so I searched for a better way and found it on your website in the debugging section, I'm talking about the modern error reporting features from OpenGL (glEnable(GL_DEBUG_OUTPUT)). But it seems to me like no one knows about it. I have seen many teachers from many universities and many OpenGL enjoyers, not use it, relying on the old debugging way, like The Cherno shows with a macro to call gl checks for every function, or not using it at all. And I think it is extremely important to be able to see what you are doing wrong for something as unforgiving as OpenGL where any error means a black screen usually. So I know for you this would feel like a big change and, and the tutorial probably makes more sense in a way as it is now, but I would want to suggest moving the debugging chapter very early, so people know about the modern debugging feature of OpenGL, and use it while coding. I think this could save them many hours of debugging. So please, if you agree with me, maybe consider moving that chapter earlier, or maybe hint at least in the first lessons that it is an important chapter and people should do it very early. Thanks!
