Fast installation  :

• All you need is jsdl.jar and libSDL4Java.so.
  
• Use the startjsdl.sh script to start a  sample. (This script needs to have jsdl.jar and lib4JSDL.so available in a specific directory)
• To start a sample just do : ./startjsdl.sh sdl.test.Video for example and you should see seomething... nothing tremendous but it works.
• Other samples may need some modifications in their source. I had the very bad idea to hardcode every images and/or sound in my source code.
  

Compilation :

For the last release i used:

• SDL-1.2.3 http://www.libsdl.org/download-1.2.html
• SDL_gfx-2.0.1 http://www.ferzkopp.net/Software/SDL_gfx-2.0/index.html This thing is optional, i want to add some features (in the future) like the rotozoom to jsdl.
• SDL_image-1.2.1 http://www.libsdl.org/projects/SDL_image/index.html
• SMpeg-0.4.4 http://www.lokigames.com/development/smpeg.php3
• jpegsrc.v6b.tar.gz http://www.ijg.org/files/

For all these packages you need to do something like ./configure ; make ; make install (Be careful for the last one you need to be root.) There is an order in the packages installation. (SDL, JPEG, IMAGE, SMPEG, GFX)

I put the binaries of those libs under the lib directory. I'm not sure it's gonna work to compile the project, but it won't work during runtime. You will need to change your /etc/ld.so.conf to add the directory and run ldconfig (as root), or copy those libs in a very known directory for libs... aka /usr/lib or /usr/local/lib.

Hope it will help someone.
