I'm ready to share y experience about this topic. To build it you can use './configure' from https://github.com/Kakadu/lablqt/tree/qml-dev/qml . In 'test' directory you will find demo ocamlbrowser-like application with QtQuick GUI interface and logic in OCaml.

I have successfully built it on  Debian sid x64 with Qt5 from git and on Ubuntu 13.04 with Qt5 from repository. Now it's time to ask what do u think about all of this.

Best wishes,

Dmitrii Kosarev aka Kakadu
