*SPACEBOX* is a C++ framework that makes creating cross-platform games and other interactive applications easier and faster by providing an added layer of abstraction between SDL + OpenGL and the project.

Users can start a project by extending only a single function, the Game class's update function. Using a standard Makefile that can be taken from the examples, the framework can export the same code to multiple platforms such as, in order of current stability, Linux, Web, Android, OS X, Windows, and Raspberry Pi.

### Raspberry Pi
Raspberry Pi builds, like Android and Emscripten, require using OpenGL ES. The build process is similar to standard desktop Linux with the `-D __PI__` compiler flag used to activate some Pi-specific code in the framework. GLEW is not available for OpenGL ES, so GLES headers are included directly from the expected system directories.

The flag `-DGLEW_NO_GLU` may also be necessary since there may not be a `glu.h` file on Raspberry Pi installations. This flag can be used by default since GLU is deprecated.
