To build this you'll need to have:

• Qt 4.8.x (libraries and compatible QtCreator)
• G++/MinGW 4.8+
• SWI-Prolog 6.5.2+ (but 6.4 should work too)

You have to be able to run swipl (and more specificly swipl --dump-runtime-variables) from the build shell. The simplest way to achieve this is to add your SWI-Prolog's .../bin directory to PATH. If you're on any GNU/Linux OS and installed swipl via the package manager everything should work out of the box, however on Windows you'll probably need to fix PATH manually (or you can alter PATH in Qt's build settings - this should work as well).
