Hi, Do you run by any chance a 32-bit only machine? This could explain the crash, the compiler has still 32-bit problems. This will be fixed in the final 0.5 release. Laurent On Sep 27, 2009, at 2:27 PM, Art Taylor wrote:

I was following the (admittedly quite old) page covering this sort of activity at http://www.macruby.org/trac/wiki/MacRubyFromObjC.
My main.m and rb_main.rb are vanilla and copied from the FlickrDemo (which runs on my system). If I reduce rb_main.rb to the bare minimum of the following, I still get the error.
framework 'Cocoa' NSApplicationMain(0, nil)
I'm assuming it's something in my ObjC code that is causing the problem -- is there a good way to zero in on it? My llvm and MacRuby knowledge is pretty rough, so I'm not sure where to drop breakpoints. If there's a "don't use <datatype>" rule of thumb, that would be great, too, as that appears to be where things may be hung up.
Thanks!
-a.
