Correct RTEMS is what used to be called an executive or kernel. It is not as limited as you might think though with major features like TCP/IP, filesystem, about 85% of POSIX 1003.1b, uITRON, and a pSOS+-like API ported to about a dozen CPUs. > There might be licensing issues as well.

RTEMS is GPL'ed with the same type of exception as the GNAT run-time. > MDC > -- > Marin David Condic > Senior Software Engineer > Pace Micro Technology Americas www.pacemicro.com > Enabling the digital revolution > e-Mail: marin.condic@pacemicro.com > Web: http://www.mcondic.com/ > > > "Michael Garrett" wrote in message > news:9nhbjd$dcg$1@suaar1aa.prod.compuserve.com... > > OAR had an Ada version of the RTEMS operating system a while back.

It has been a long time but it can be dug up. :) When it was new, there was very little feedback to it. The C implementation got a lot more interest and when the C version was used as the run-time for GNAT, it seemed to satisfy the same goal without duplicating effort. -- Joel Sherrill, Ph.D. Director of Research & Development joel@OARcorp.com On-Line Applications Research Ask me about RTEMS: a free RTOS Huntsville AL 35805 Support Available (256) 722-9985
