If you want to develop with QML 2.0 and Qt5, the base packages don't seem to exist in repository for 12.04. What PPA should I add? Is it a binary installer? a compile the toolkit yourself?
Those aren't separate questions, they're just possible tracks to an answer.
I'm asking because if you want to develop for Ubuntu Phone, but still have a rock solid LTS development box, this seems the appropriate path.
How can I install Qt 5.x on 12.04 LTS?
