How to Use GLFW in XCode

First, download the GLFW source code.

Extract the tarball to a directory.

Open a terminal and cd to the extracted directory. Run cmake (if not already installed, install it!):

%>cmake .

Then,

%>make

%>make install

The header files will be placed under a GLFW directory in

/usr/local/include/

and the library file in

/usr/local/lib/

To now use the libraries, start a new XCode project.

Select “OS X Application” and “Command Line Tool.” Name the project whatever you like and save it somewhere.

The first step is to link the search paths for the libraries and header files. With your project selected in the Project Navigator pane, select the “Build Settings” tab. In the search box, type Search Paths.

In header search paths, add

/usr/local/include/

and select recursive.

Similarly, under library search paths, add

/usr/local/lib/

and select recursive.

Now, click the “Build Phases” tab. Under “Link Binary with Libraries,” we must add the appropriate libraries necessary for OpenGL and GLFW to function. First add the OpenGL framework. (You may type “OpenGL” in the search on the dialog box that comes up to quickly find it.)

Finally, add the GLFW library (libglfw3.a, located in the /usr/local/lib/ directory). In the framework add dialog box that pops up, click “Add Other.” Now this is a bit tricky, because the OS X file open dialog won’t allow you to select the /usr/ folder by default. The workaround is to download TinkerTool, and select “Show hidden and system files,” then click “Relaunch Finder.”

Now, make the /usr/ folder a favorite as described in this post. The usr folder will now show up in the file open dialog for easily selecting the library.

Your Build Phases pages should now look like this:

Now, to test to see if it works, copy GLFW’s sample code from here into your main.cpp, then build and run.
