Brad, If you google "dyld: Symbol not found: ___dso_handle", you'll come up with the following messages...
http://gcc.gnu.org/ml/gcc/2006-03/msg00712.html http://gcc.gnu.org/ml/gcc/2006-03/msg00718.html http://gcc.gnu.org/ml/gcc/2006-03/msg00735.html So it certainly sounds like your cctools is stale. Note that the issue with the __Unwind_GetIPInfo will likely still exist but you will only run into if you set the MACOSX_DEPLOYMENT_TARGET. A generic build or one without building java won't show the issue on gcc trunk. Jack
