Hi Todd, any chance to get this bridge working with current VM? I managed to compile it with latest svn version of the unix VM (stable versions did not compile on Intel Mac for some reason) and it seems there even was some message exchange between VM and ObjC runtime, but after that I got primitive failure in ByteArray>>integerAt:size:signed: e.g. in FFIPlugin>>primitiveFFIIntegerAt and I was not able to fix that.

I would give my little finger for a chance to write native Cocoa software in Squeak.

Walkback follows:

ByteArray(Object)>>primitiveFailed Receiver: a ByteArray(160 58 97 0) Arguments and temporary variables:

Oh, that's kind of cool. When we were working on the objective -c bridge, we were doing a lot of nutty introspection to try to fake that info. We could probably do a lot better with that stuff. If I get an free time I'll look at it. If you want to try it yourself, the objective-c bridge is on squeaksource.
