Unfortunately when I clicked the link you posted I got a "You do not have permission to access this page" error. Do you mind pasting the content directly?
Shastzi: Just to be clear, I do have Ubuntu MATE installed on the Pi 2, but the Sleepyhead Ubuntu version seems to be for AMD 64b hardware. (It was a long shot, but I had to try.)
So I'm left wondering if there's a way to "build from source", whether anyone has ever successfully installed SH on a Pi...
Thanks very much for posting Alan, it's good to know someone has done it, or at least gotten close. I'll try it under Raspbian first and if that doesn't work will try Ubuntu.
I just tried using Archangle's make procedure, but with Ubuntu 16.04 freshly installed on a Pi 2.
Unfortunately I couldn't create an executable and make failed with:
/usr/bin/ld: cannot find -lGLU
collect2: error: ld returned 1 exit status"
I tried again, using the BrokenGL version:
$ qmake DEFINES+=BrokenGL
$ make -B
... but got the same error.
I'm not familiar enough with Linux to understand what's going wrong but will try these steps again under Raspbian.
Couldn't get it to compile under Raspbian either. The make procedure failed with
Project ERROR: Unknown module(s) in QT: serialport
You do not have all the prerequisites installed. These are listed in the "how to compile on Linux" instructions.
