tools/Linux/packaging/mk-debian-package.sh does everything for you, from a clean git tree. But it won't work(ootb) in a cross compile env.
Its won't build any depends either, they must be available as system installed packages.
So, it should work when running it on the pi directly Or maybe a qemu-arm pbuilder setup...

How do you build your other packages?

I cross compile with unified build system (e.g. with FernetMenta's instructions).
Building on Pi (or qemu) would be pretty slow.

Is it possible to cross compile, and then mount the directory from Pi (or qemu), and then run mk-debian-package.sh?
