Segmentation fault when including glad.h

Question

I am following the GLFW guide to getting started but I can\'t seem to make it run with GLAD.

Here\'s my C file (prac.c)

#include 
#include         


        

Answer 1

You have to call initialize glad before calling any OpenGL instruction.
That means gladLoadGL() has to be done before glGetString(GL_VERSION):

glfwMakeContextCurrent(window);

gladLoadGL();

printf("OpenGL version: %s\n", glGetString(GL_VERSION));
