Hi, thanks for your reply.
I'm not sure think that's quite the same thing. I believe that facilitiates the installation of QT libraries onto the target and therefore you can run any standalone QT development on the target if you deploy the built rootfs.
However I actually want to add my app, not as standalone but as part of the kernel/uboot/rootfs project. There is an app directory and you can add 'template' apps but I want to add a full QT GUI application.
Thanks again though.
