I've been looking through some of the missing components from QT which were supposedly removed due to size. It seems like the most important ones relate to transformation functions, dialogs and network protocols.
The dialogs seems easy enough to deal with: qinputdialog.h just needs a few small changes and it will compile just fine. As for transformations I've just used replacement functions I've found elsewhere or written myself.
The networking protocols are a bit more tricky. The lack of qurloperator and qnetworkprotocol.h is a bit of a loss and I don't think they would be easy to port back in. Besides rewriting what I need or doing the trick that lets you compile libqte.so.3.3.3, have any of the more experienced programmers developed any workarounds?
I've checked out the code to zaurss and I have no idea how Nokubi got it to compile. As for some of the other applications I've looked at they tend to only do the minimum networking possible.
