Re: [sdljava-users] Problems compiling in Mac OSX

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

Greetings Nuno,

SDLJava has not yet officially worked on OSX.  However regardless I 
think it should work but I don't have an OSX machine to verify this myself.

The error you are getting, java.lang.UnsatisfiedLinkError, is because 
the virtual machine cannot find the library.  You need to pass the 
location of the SDLJava shared library as a -D switch.

$ java -Djava.library.path=<SOME_PATH>

Give that a shot and let me know if it works!

BTW:  Did you ever resolve your earlier problems??
