The QNX Realtime Platform is a Realtime OS
developed by QNX Software Systems Ltd
It contains, at its core, the Neutrino
Kernel and the Photon
microGUI windowing system, which could be compared to the GNU/Linux
Kernel and The X Windowing System
The QNX Realtime Platform is free
for anyone to use. The only catch
is for developers. If you develop products utilizing the QNX Realtime Platform or develop for the QNX Realtime Platform, a fee may be requested.
Porting is generally easy due to its 100% POSIX
compliance, standard GNU
development tools, and X-windowing system compatibility layer (XPhoton
). Usually it's just a recompile
