= What's Ruby/SDL
Ruby/SDL is the ruby extension library to use SDL.
SDL(Simple DirectMedia Layer) is a cross-platform multimedia library
designed to provide fast access to the graphics framebuffer and audio
devices. See http://www.libsdl.org/ if you want to know SDL in detail.
= Platform
This library supports Linux, Win32, MacOS X.
This library perhaps works on FreeBSD and other standard
Unix-like systems.
= Library Needed
Ruby/SDL needs Ruby and SDL and optionally uses SDL_image, SDL_mixer,
SDL_ttf, SGE, OpenGL and SMPEG.
Indispensable
Ruby http://www.ruby-lang.org/
SDL http://www.libsdl.org/
Optional
SDL_mixer http://www.libsdl.org/projects/SDL_mixer/index.html
SDL_ttf http://www.libsdl.org/projects/SDL_ttf/index.html
SDL_image http://www.libsdl.org/projects/SDL_image/index.html
SGE http://www.etek.chalmers.se/~e8cal1/sge/
SMPEG http://www.icculus.org/smpeg/
SDLSKK http://www.kmc.gr.jp/~ohai/sdlskk.en.html
= INSTALL
Some packages are available: Debian's .deb, FreeBSD's ports,
or Windows' zipfile.
RubyGems are also available. You can install Ruby/SDL:
gem install rubysdl
You can install from source code as follows:
(1)install Ruby
See Ruby's document and install.
(2)install SDL
Extract SDL's source and run './configure'.
And run 'make','make install'.
(3)install SGE
Run 'make' and 'make install'.
(4)install SDL_mixer, SDL_ttf, SDL_image, SMPEG and SDLSKK
See documents of these libraries and install them .
(5)install this extension library,Ruby/SDL
Run 'ruby extconf.rb','make' and 'make install'.
(6) (Mac OS X user only) install rsdl
Run 'gem install rsdl'.
rsdl is a wrapper of the Ruby interpreter. This wrapper
prepares Cocoa framework before running the interpreter.
= Use SGE without installing the library
You can use SGE without intalling:
gem install rubysdl -- --enable-bundled-sge
or
ruby extconf.rb --enable-bundled-sge
However, please do not use this option if you have
other way. Please install SGE separately if possible.
= USE Ruby/SDL
Write "require 'sdl'" in your Ruby script.
If your system is OS X, you must use rsdl command
as an interpreter instead of ruby command.
See following documents and samples if you want to know the detail.
sample/*.rb
Ruby/SDL samples. In some scripts, you have to prepare data such as
"sample.wav" and "sample.mpg".
rubysdl_ref.en.html

= OpenGL
You can use OpenGL with this library.
(1) Setup OpenGL and SDL.
(2) Install ruby-opengl (http://ruby-opengl.rubyforge.org/)
(3) Run "ruby extconf.rb", "make", and "make install"
(4) Write "require 'sdl'; require 'opengl'" in your script.
We use OpenGL through ruby-opengl.
Please see SDL's document,OpenGL document and sample/testgl.rb .
