Running Qt/QML applications on latest Snappy

[Darren Landoll]

I've been working with the latest versions of Snappy core and Mir to try
getting a Qt/QML application running successfully. Not sure if this list or
mir-devel is the best place for this topic, so starting here first.

I am building the amd64 oem and mir snaps and then running
ubuntu-device-flash to create either a stable or edge based image for 15.04
(in developer mode).

For initial testing I am using deb2snap to build a snap for the qt5
declarative clocks example, based on this guide:
https://docs.google.com/document/d/14msTXe_cFulk9z4jFptEjFJzZx58b1mWU_r4VivLkfA/edit?pli=1

The target device is a x86_64 based touchscreen and I am currently booting
my test images from a USB stick. The machine boots up successfully and
displays the empty/default mir server (w/ mouse cursor). When I install and
try to run the QML clocks example, I get the error shown below. Any ideas
or feedback would be appreciated.


$ qtdeclarative5-examples-amd64.clocks

Thanks!
