OpenGL glBufferData

Question

I am using the following tutorial as a guide to make a model loader and I have come across a problem. When I use

glBufferData(GL_ARRAY_BUFFER, vertices.size() * sizeof(Point3D), &vertices[0], GL_STATIC_DRAW);
glFlush();

I get the following problems:

• Error: identifier glBufferData is undefined
• Error: identifier GL_ARRAY_BUFFER is undefined
• Error: identifier GL_STATIC_DRAW is undefined

I have included the libraries into the linker so that should not be the problem. I am including glut.h, Windows.h and gl.h so that shouldn't be the problem either.

I have now added the glew library in both the linker input properties and the source code but I am getting a completely new error now (runtime). I took a screenshot of it:

I find this question is quiet simple to be solved.
You can visit Glad and generate the API with the target version of gl you looking for. Unzip the file and include the path to /glad/include in your IDE, and, the error gone!

Note: If you #include <glad/glad.h> and <GLFW/glfw3.h> in the same time, remember to add a preprocessor : #define GLFW_INCLUDE_NONE in front of them. Ref : glfw tutorial
