I'm trying to start developing for Ubuntu and Ubuntu phone, but I get an error:
qmlscene: cannot find qt installation of ''
when I attempt to run my application in Ubuntu from the command line. I'm very new to Linux, so if you could fully explain what I need to do to fix it, then that'd be great. I'm running Ubuntu 13.04 in a VirtualBox virtual machine on an Asus N56VZ laptop. I installed the Ubuntu SDK using the instructions on http://developer.ubuntu.com, so I really have no idea what's wrong.
