I installed the Qt SDK from the Wheezy repository, using Synaptic, which pulls in QtCreator and all the base dependencies. For the SDK, the repo just says version 2, while QtCreator is 2.5.0 and supports Qt 4.8.1. Re: versions: While an eventual wide audience would be great, my order of priority is: my N900, then Fremantle repositories, then other maemo versions, so ensuring compatibility with all Qt platforms isn't a consideration to start with. Unfortunately, the IDE seems inconsistent with its own Help and when creating a new project, it is not possible to target any mobile devices (it only allows Desktop). When I installed all the packages, Synaptic still shows a list of QtMobility packages, but not installed. Is QtMobility ever embedded into QtCreator or do I need to actively install them, and are they even necessary for N900 C/C++ development? Although I have no problem with compiling from source, if the Debian maintainers have done the hard work of sorting out the dependencies, I would rather use the official binaries.
