glGenBuffers not defined?

I'm using windows and I notice that a 开发者_开发问答lot of functions are grayed out because I guess #ifdef GL_GLEXT_PROTOTYPES is not defined. One of these is the VBO extension. Should I just define GL_GLEXT_PROTOTYPES? Otherwise how else can I use VBOs since im using OpenGL32.dll (I want my application to have no dll dependencies not included in Windows by default.) Thanks

Yes, it's quite normal and expected to have something like:

#define GL_GLEXT_PROTOTYPES

#include <GL/GL.h>

If you're trying to write OpenGL 3 compliant code, you'd normally change that to:

#define GL_GLEXT_PROTOTYPES 1
#define GL3_PROTOTYPES 1

#include <GL3/GL3.h>

I recommend that you use GLEW to get rid of that problem.

It's a long story, but resuming, Windows' OpenGL library only exposes OpenGL 1.1 entry points, so all functions beyond that version are loaded with wglGetProcAddress. GLEW solves this problem by doing that.

Just link to GLEW and GLU/GLUT (if you use them).

You can use glad to provide glGenBuffers for you.

And if you're using the Glew OpenGL extension, make sure you initialize it.

glewInit();

Otherwise nothing will be drawn.
