What do you need to know about the OpenGL loading library?
OpenGL Loading Library. An OpenGL Loading Library is a library that loads pointers to OpenGL functions at runtime, core as well as extensions. This is required to access functions from OpenGL versions above 1.1 on most platforms. Extension loading libraries also abstracts away the difference between the loading mechanisms on different platforms.
Is the OpenGL extension Wrangler library compatible with Linux?
The OpenGL Extension Wrangler library provides access to all GL entrypoints. It supports Windows, MacOS X, Linux, and FreeBSD. As with most other loaders, you should not include gl.h, glext.h, or any other gl related header file before glew.h, otherwise you’ll get an error message that you have included gl.h before glew.h.
How does an extension loading library override gl.h?
Most extension loading libraries override the need to include gl.h at all. Instead, they provide their own header that must be used. Most extension loading libraries use code generation to construct the code that loads the function pointers and the included headers.
