I guess I'm still a bit stuck in the era where the target had very limited resources. For first time users, this is much easier, and for a workshop, I've indeed supplied a dozen boards that had editors, compilers and library headers pre-installed for immediate development. That will work for hello-world style apps, but for more complex projects that draw in a few dozen complex libraries (gstreamer comes to mind) this is not going to be very satisfactory. What he was asking for was "How do I use the cross-compile environment to develop my own application and run it on the target machine?" -- Mike Looijmans
