I don't think there is a public Army RTEMS site any longer. The current RTEMS source is at ftp.oarcorp.com. The last Ada release is also there since more than a few people had asked for it. > Looks like the new versions are in C. This is correct. V3.2.1 was the last version in which the C and Ada implementations were feature-wise in sync. About this time, the GNAT project was started and we decided that it made more sense to provide Ada support for RTEMS by focusing on providing a free full-featured embedded run-time for GNAT. This is accomplished via as complete an implementation of POSIX 1003.1b as is possible without actually having UNIX processes. We made the decision because we felt this resulted in a solution more appealing to more people. I have always enjoyed the irony that C/C++ supporters enhancing RTEMS are improving it as an Ada run-time. :) --joel 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
