FreeGLUT doesn't have any prebuild frameworks we can use with the OS X compilers. Fortunately, Mac OS X is a type of Unix and we can use unix commands to get it to build and install freeGLUT on OS X. Unfortunatey, OS X has some quirks we need to deal with.

1) The first issue is that newer versions of OS X don't have X11. You'll have to install XQuartz, a quartz based port of X.org. Download the dmg and install it.

2) Download the latest source from the freeGLUT website.

Extract the archive, open a terminal window, cd to the extracted folder.

3) Configure the installation using this command in the extracted folder
env CPPFLAGS="-I/opt/X11/include" LDFLAGS="-L/opt/X11/lib" ./configure
When you installed XQuartz, it installs X11 to /opt/X11/lib. This command configures the build and tells it to look in /opt/X11/include for headers and /opt/X11/lib for library files.

4) In freeGLUT 2.8.0 there's a bug in the source code that causes to break in OS X. In the freeGLUT source directory you extracted go to progs -> demos -> smooth_opengl3 and open up smooth_openg13.c.

Between lines 101 and 102 there's a bunch type definitions that are already in glext.h that cause a conflict.

All you have to do is sandwich it in some ifdef macros to make it stop complaining.

5) Then in the terminal enter the make command (make sure the terminal is in the directory you extracted)
make all
Now using root privileges, install the library with the command:
sudo make install
6) Now that you've installed the development libraries, it's time to start up your IDE/compiler.
make all 出現錯誤：

有問題，於是把修改的巨集去掉。重新make all。沒有報錯。make install.

再參考：

http://lazyfoo.net/tutorials/OpenGL/01_hello_opengl/mac/xcode/index.php

1)Start up XCode and create a command line tool project.

Remove the main.cpp file autogenerated for the project as we're not using it. Go download the source for lesson 01. Add the source files inside to your project.

2)Click on your project to reveal the Build Settings tab. Click on the Build Settings tab. Under in the Linking section in the Other Linker Flags add -lGLUT. This will make the project link with the freeGLUT Unix library we installed.

3)In the Search Paths section add
"/opt/X11/include" "/usr/local/include"
to the Header Search Paths and
"/opt/X11/lib" "/usr/local/lib"
to the Library Search Paths

This makes it so XCode will find the header/library files for XQuartz (/opt/X11/) and freeGLUT (/usr/local/).

4)Click on the Build Phases Tab, open up Link Binary with Libraries and add the OpenGL framework.

Now build. If there are any errors, make sure you didn't skip a step.

Now that you have OpenGL and freeGLUT compiling, it time to go onto part 2 of the tutorial.

該步很順利，"/opt/X11/lib" "/usr/local/lib"
to the Library Search Paths，圖片顯示有誤
