I download Qt from qt.io, and at build time, I set env var QTDIR to the place where I unpacked it - the parent of the bin folder - e.g. $HOME/Qt/5.2.0/gcc_64. Getting the version of webkit used in an upstream Qt build is not always so clear. I found this answer: http://stackoverflow.com/questions/29012164/what-webkit-version-is-qt-5-4-1-using-on-osx Now, looking at the major version there, I am not exactly sure how helpful that is. :-) Looking at this page, however, shows that it roughly corresponds to the version of Safari in latest version of OS X 10.10. https://en.wikipedia.org/wiki/Safari_version_history If you download Qt 5.4.2 with its Qt Creator on a desktop machine, it is fairly quick and easy to build WebVfx, and use its Viewer tool to test your HTML. Then, you can work on the build against MLT for your headless machine.
