I've removed the explicit JAWT link on OSX and cleaned up some of the other OSX-specific options. You will probably need to build against the 10.3sdk instead of 10.4sdk, and possibly force the use of gcc-3. I don't have a 10.3 system to test on, so I'd rather not muck about with that until someone shows that it works.

I've been trying to get JNA running on a Mac running 10.3. As soon as I call anything I get an exception trying the load the JNA libjnidispatch.jnilib. It seems that this has been linked with the AWT dynamic library, but seems to be trying to load it from:

/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/ Libraries/libjawt.dylib

This works fine when Java 5 is installed, but on 10.3 it won't be. I fiddled about with the makefile to try and get it to link to:


Which I figured would be valid on any machine, but this is a symlink that resolves to Java 5 (on my dev machine) so I wind up with a library with the same problem. I confess to knowing next to nothing about linking dynamic libraries on OS X so am a bit stumped. Surely there must be a way of linking to 'the current version' ?

Has anybody else got JNA running on a Mac that doesn't have Java 5 installed?


p.s. JNA is a great library by the way: Once I 'got' how to use it, calling the odd bits of native code I need has been a breeze. Thanks!
