The lines above are just generic "I'm exiting now" messages, the actual cause of the problem is whatever messages were printed right before this. That aside since you're in libjava you're probably running into this: <http://gcc.gnu.org/ml/java/2005-11/msg00004.html>. Without that patch you will get an error about multiple symbols in libgcj.a when linking. The patch was just only checked in yesterday, so if you're using a release version or a snapshot you will have to manually patch, or "svn up". Brian
