Re: [sdljava-users] Mac OS X

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

Hi Fredrik,

I would love to get sdljava working with Max OS X.  I can't offer to 
much aid at the moment however because I don't have access to an OS X 
machine.

There might be some special stuff you have to do to have it work under 
Eclipse.  Check the list archives.  I know people have gotten it to work 
under Eclipse but I think they had to explicitly specify the path to the 
shared libraries.  I've added a VM switch to allow this. 

Having all the classes in the jarfile should be fine.  Unless you 
actually reference image or gfx then the VM won't attempt to load those 
shared libraries.  The System.loadLibrary() call is only made if the 
class is actually loaded by the runtime which won't happen unless its 
referenced by come other class.

Would really appreciate it if someone can get this working on OS X.  
Please post the appropriate Makefile, documentation, etc... that are 
needed to make it work and I'll include it in the next release.  If 
someone is willing to build me binaries for OSX before a release I can 
include those for the public.
