How can I install Qt 5.x on 12.04 LTS?

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?

This can be done by adding the following PPA to your system:

ppa:canonical-qt5-edgers/ubuntu1204-qt5 (Click here for instructions on using PPAs.)

You can usually do this with the following commands:

sudo apt-add-repository ppa:canonical-qt5-edgers/ubuntu1204-qt5

sudo apt-get update

The next step is to install the necessary packages for Qt5 / QML 2.0 development. You can do that by running these command:

sudo apt-get install qtdeclarative5-dev

This will install the headers / libraries necessary for development with desktop Qt and QML. You will also probably want to grab the latest release of Qt Creator from this page.

I've found that Qt Creator sometimes has problems finding your new Qt5 installation. If that is the case, perform these steps:

open it up and go to Tools->Options

click the "Build & Run" section in the left menu

click the "Qt Versions" tab

click "Add..." and enter the location that corresponds with your OS:

32-bit: /usr/lib/i686-linux-gnu/qt5/bin/qmake

64-bit: /usr/lib/x86_64-linux-gnu/qt5/bin/qmake

Previously these packages were located here:

ppa:ubuntu-sdk-team/ppa

According to the "Ubuntu SDK Team": Old Ubuntu 12.04 LTS Qt 5.0 packages have been moved to https://launchpad.net/~canonical-qt5-edgers/+archive/ubuntu/ubuntu1204-qt5/, and that seems to have occurred sometime in May of 2016.
