Hi Alex - sorry for the slow reply, got bombed day and night at work
and just emerging from my turtle shell again. If you have some advice
I might give it another go. Last time I tried, the toolchain didn't
deduce the platform correctly in some areas so some hacks had to be
made to the platform checking macros to get it to find the correct
windows implementations. This might be something peculiar to the mingw
toolchain, since the problems are related to macro checkers for
windows. Do you have any good references re cross compiling qt?

As far as choice of gui goes, both do the job I reckon - we're talking
about control here, not a business extravaganza showpiece. Wxwidgets
is intended to be small and light, qt intended to be more fully
featured + environment classes as well - both have a good context. We
were originally using qt before we started using the ros, so we just
stuck with what we knew.

Regards,
Daniel
