I have an application that needs to access some constants - KeyDirectObject from AppleEvents.h, requiring AE.bridgesupport; and KInternetEventClass and KAEGetURL from InternetConfig.h, requiring HIServices.bridgesupport. I had to upgrade to the BridgeSupport Preview 3 for the constants to be 'seen'. I've built the app by amending the Embed target slightly; I've added the --bs flag (slightly unfortunate name there !) which has produced the BridgeSupport directory under Contents/Resources as required. I'm using the debug build atm. I have two observations: a) running the app on Snow Leopard 10.6.6 works just fine, but running it on a MacBook Pro build with Snow Leopard 10.6 (i.e no upgrades applied) results in a crash - stack overflow, Job appears to have crashed: Abort trap. As the purpose of this build is to allow the app to run on Macs that have neither MacRuby installed nor the BridgeSupport preview, we've taken to redefining these constants in rb_main.rb and dispensing with the BridgeSupport files; we'd like to address that. I'm happy to work with someone to try to figure out what is going on and to fix it. b) the --bs flag increases the size of the app by about 5mb. We only need the two mentioned - can we amend the script to make sure only the two mentioned above get included? Incidentally - I noticed that there were 9 .dylib files in the BridgeSupport folder - are they supposed to be there? Martin
