The function glVertexAttribDivisor when used with CMake - it just throws the following error during compilation, which means that function is not imported.

error: 'glVertexAttribDivisor' was not declared in this scope; did you mean 'glVertexAttrib4iv'

I am currently using GLAD for loading openGL, like below:

if (!gladLoadGLLoader((GLADloadproc) glfwGetProcAddress)) {
    std::cout << "Failed to initialize OpenGL context" << std::endl;
    return nullptr;
}

int gladInitRes = gladLoadGL();
if (!gladInitRes) {
    fprintf(stderr, "Unable to initialize glad\n");
    glfwDestroyWindow(window);
    glfwTerminate();
    return nullptr;
}

And printf("OpenGL version %i.%i\n", GLVersion.major, GLVersion.minor); prints out OpenGL version 4.2

Where is the GLAD header, and is the function declared there? – Nicol Bolas Mar 25 '21 at 05:54
How do I make sure it is declared there? It doesn't seem like atm – Rohan Asokan Mar 25 '21 at 13:20
Look at the file and search for the name of the function. – Nicol Bolas Mar 25 '21 at 13:20
Its not there!! – Rohan Asokan Mar 25 '21 at 16:45
Sooo - should I try to get a different version of glm or something?? – Rohan Asokan Mar 25 '21 at 16:45
GLM is a math library; it has nothing to do with this. And if the function isn't part of the loader (aka: GLAD), then you didn't generate the loader's header file correctly. – Nicol Bolas Mar 25 '21 at 17:54
Ahh! Well that could be possible as the my source of GLAD is from the internet. And yes sorry for the glm :) - it gets confusing ngl - everything is GL. I will look into generating a new one. Thanks! – Rohan Asokan Mar 25 '21 at 17:58
