Thanks, this did help.  My biggest problem was that the Poky tree I was
trying to use had grown a permission problem so I could no longer execute
the compiler (result of moving the tree between machines - pure cockpit
error, sorry).  Once I restarted a new Eclipse project with a proper tree
(again I forgot the meta-ide-support package - is this documented?), things
have started coming together.

Next step - try to debug this project on my remote board.

Thanks again
