One approach that some of our customers are exploring is the use of our GNORT (GNAT No Run-Time) technology that provides a subset of Ada which generates absolutely ZERO bytes of runtime. This means that you can simply generate object files and then run them to the bare board using whatever low level toolset is appropriate. One customer for example is using OS/2 as the development environment, and then GNORT for actual delivery to the target system (which is a bare board x86). -----== Posted via Deja News, The Leader in Internet Discussion ==----- http://www.dejanews.com/rg_mkgrp.xp Create Your Own Free Member Forum
