There seems to be a dependency in the AppGameKit runtime, which will create trouble when producing apps to run under linux. Some legacy sound library called 'libopenal'. This is not part of the standard install of Ubuntu 16.04. Fortunately the fix is easy enough (on Ubuntu/Debian):
sudo apt-get install libopenal-dev
That sorts it out. Be aware though that if intending to copy your app to another linux box / cloud host / whatever - you need make sure that and other dependencies are installed. If not all you get when trying to run your app is a big fat nothing. Well, an error message if trying to launch from the terminal - but nothing if trying to launch from file-browser.
