I started to think about commercial detection and set about defining a method that would work in my local area, east coast Australia. All work took place on my Windows development  machine and by late 2015 the technique was thought to be worth taking to Linux and Qt. I have finished the translation to Qt on MythBuntu.

A GUI manages the acquisition and maintenance of icon data, whilst a Data Module deals with the Myth interface, CSV files and code to achieve a flagged outcome.

To create a clean dev environment I installed Mythbuntu 0.28 on a spare box, Ansibled, git clones the source, configured, made and compiled, all without a hitch. The objective here was to have the build tree complete with source, headers, object code and shared compiled libraries.

Hi Glen,

If I were you, I would create a sub-directory under mythtv/programs with the name of the executable you want to compile, then use a .pro file from another program as a template. May I suggest mythshutdown.pro. Just be sure to change the base name to match the name of your sub-directory. You'll notice that mythshutdown.pro includes other .pro files. Those includes take care of a lot of the boilerplate needed to get a working .pro file.

HTH,
Helen
