How to Set Up GLFW Library

GLFW is a library to open a window with OpenGL graphics visualization.

There are three ways to set up GLFW:

1. using package manager (for Mac and Ubuntu)
2. download pre-build library (Mac and Windows)
3. build the source code (for all OSs)

This class support the option 1 and 3. Below, we discuss these options in detail for each OS

Mac

Install from Package Manager

for Mac, install glfw using package manager brew as

$ brew install glfw

Install from Source Code

Alternatively, you can build glfw from source code and put the library under external/glfwlib with

$ git submodule update --init external/glfw
$ cd external/glfw
$ cmake .
$ cmake --build . --config Release
$ cmake --install . --prefix ../glfwlib

Make sure you have a header file glfw3.h at

pba-<username>/external/glfwlib/include/GLFW/glfw3.h

Ubuntu

Install from Package Manager

For ubuntu, install glfw using apt-get as

$ sudo apt-get install -y libx11-dev xorg-dev \
                          libglu1-mesa libglu1-mesa-dev \
                          libgl1-mesa-glx libgl1-mesa-dev
$ sudo apt install -y libglfw3 libglfw3-dev
$ sudo apt install -y libglew-dev

Build from Source Code

Alternatively, you can build glfw from source code and put the library under external/glfwlib with

$ git submodule update --init external/glfw
$ cd external/glfw
$ cmake .
$ cmake --build . --config Release
$ cmake --install . --prefix ../glfwlib

Make sure you have a header file glfw3.h at

pba-<username>/external/glfwlib/include/GLFW/glfw3.h
