Compiling Textbook Style Code on Linux

You can write programs on Linux too. It's been a while, but I have had success in the past. These instructions were last updated in Jan. 2015, but have not yet been thoroughly tested. You may also be able to do it with a BSD Unix.

With Unix OS's you need to be careful about your graphics card and its drivers. Third-party Open Source drivers usually have poor support for newer versions of OpenGL, so I recommend getting proprietary drivers for AMD and NVIDIA cards. Intel released open source drivers for their hardware which are part of the Linux kernel.

Get freeglut

You will need to install freeglut on your system. Your Linux distribution probably already has freeglut installed or available through the package manager. Be sure that you have both the libraries and development headers installed.
For example on Ubuntu Linux or Mint Linux you can get freeglut3 and freeglut3-dev like this:
```
sudo apt-get install freeglut3 freeglut3-dev
```
If you can't find freeglut packages for your distribution, you can find the source code on SourceForge:
http://freeglut.sourceforge.net/index.php

untar/gzip it, go into the folder, then type
```
./configure;make;make install
```

Get GLEW

You also need to install GLEW on your system. Your Linux distribution probably might have itavailable through the package manager. Be sure that you have both the libraries and development headers installed.
For example on Ubuntu Linux or Mint Linux you can get GLEW freeglut3-dev like this:
```
sudo apt-get install libglew1.10 libglew-dev
```
If you can't find GLEW packages for your distribution, you can find the source code on SourceForge:
/index.php

untar/gzip it, then move to the project directory, and type:
```
sudo apt-get install libXmu-dev libXi-dev libgl-dev dos2unix
./configure;make;make install
```

Compiling and Linking with OpenGL, freeglut, and GLEW

You should be able to compile as usual, but you need to link an OpenGL project against libGL.so and probably also libGLU.so. Freeglut projects also need to linkd against you need to link against liglew.so. Finally GLEW projects need to link agains libGLEW.so.
Briefly, to compile and link a program that uses all three, use these options
```
 g++ filenname.cpp -lGLEW -lGLU -lGL -lglut 
```
