OpenGL 4 Shading Language Cookbook - Third Edition

There's more...

The previous example only demonstrated how to compile a vertex shader. There are several other types of shaders, including fragment, geometry, and tessellation shaders. The technique for compiling is nearly identical for each shader type. The only significant difference is the argument to glCreateShader.

It is also important to note that shader compilation is only the first step. Similar to a language like C++, we need to link the program. While shader programs can consist of a single shader, for many use cases we have to compile two or more shaders, and then the shaders must be linked together into a shader program object. We'll see the steps involved in linking in the next recipe.
