Ah, okay. Sorry, then. As far as I know, the Qt packages for Maemo are packaged similarly to most distros (at least, the ones that split the packages, like Debian). To do a Hello World app, you'd need at least QtCore, and the rest could be installed as needed. I haven't played around with Qt on Maemo (or at all, much), but in my understanding, it should work more or less like on your SuSE box. Since you can run apps in scratchbox, it may be easier to just try a quick Hello World in there, before you try packaging anything for Maemo.

Cheers,
