Re: [sdljava-users] Problems with JavaSDL.. I've been trying for hours to get this to work.

[Ivan Z. G. <iva...@ya...>]

Sounds like you got it working now.  Thanks everyone for your help on 
the list.

Regarding the portability -- it is just assumed that the SDL libraries 
can be resolved and are installed properly.  Either present in 
c:\windows\system32 or in some other way configured so that the VM can 
locate the required libraries.  I will update the INSTALL doc to be more 
clear on this aspect.

If you were to actually ship a game created with sdljava then you would 
want to package up the SDL dll files you need (SDL, SDL_mixer, etc...) 
and have the installer for your game install these in the appropriate 
places.  The users of your game should not have to deal with anything 
special.  It should follow a standard install process like that for any 
game you buy off the shelf.

Again I will update the documentation to be more clear and hopefully 
avoid this problem in the future.  Please continue to send 
questions/comments/etc...
