Hi, You might want to add the JADE library (http://jade.dautelle.com) to the list of projects of interest to GCJ users. Indeed, JADE is a LPGL library which allows GCJ to run hard realtime applications with no GC ever! It has also the side effect to significantly accelerate code execution (3x-5x). I think it would be the perfect complement to GCJ for embedded systems. Ref. JADE realtime FAQ at http://jade.dautelle.com/api/com/dautelle/realtime/package- summary.html#FAQ Let me know your opinion. Regards. Jean-Marie Dautelle.
