Better would be GNAT on Lynx. Lynx (http://lynuxworks.com) is a true real-time system, with a POSIX interface. AdaCore offers full support for this combination. I use it at work, but on x86 targets. Lynx is not as nice for running development tools (such as Emacs) as Linux, but it is nicely real-time. Writing device drivers is easier in Lynx than Linux. And the AdaCore support is wonderful. Hmm. I run Emacs on Lynx on x86; Lynuxworks offers a "self-targeted" gcc for that CPU. I think they don't offer a self-targetd CPU for PowerPC; you have to use cross target. I don't know why; you should ask AdaCore and/or Lynx. In any case, GNAT + Lynx on PowerPC is still more real-time, and more supported, than GNAT + Linux on PowerPC. -- -- Stephe
