Using the GLFW library

The GLFW library hides all the complexity of creating windows, graphics contexts, and surfaces and getting input events from the operating system. In this recipe, we build a minimalistic application with GLFW to get an empty window onto the screen.

Getting ready

We build our examples with GLFW 3.4. Here is a JSON snippet for the Bootstrap script so that you can download the proper library version:

{
     "name": "glfw",
     "source": {
           "type": "git",
           "url": "https://github.com/glfw/glfw.git",
           "revision": "3.4"
     }
}

The complete source code for this recipe can be found in the source code bundle under the name of Chapter01/02_GLFW.
