I had trouble installing SnipSnap in Expert mode on Cacao 0.93. I got this exception in the log: java.lang.LinkageError: loading constraint violated XXX add message I think I diagnosed the problem to this line in resolve.c: name = container->name; /* XXX should this be declarer->name? */ Yes, I think it should be declarer->name (or maybe this case doesn't need to be checked at all? I'm not really familiar with class loading constraints). Anyway, when I changed it to declarer->name, the exception went away. But I don't really understand loading constraints, so I could be wrong.
