Going from Linux to QNX6 involves about the same amount of fuss as going to
another Unix (but it is harder than going between Linux distros of course).
Do not be afraid if configure does not finish - those are usually minor
problems. Linux people are so used to the fact that configure ‘just works’,
they forget it was designed to be a porting tool, not ‘make extension’.
Little digging will be rewarding. Look into the configure script and see why
it fails.
