@raven-worx @jsulm And therefore I am looking for the way how to mangle the VCRT library into my project, it's mandatory.

@okieh said: I'm a little bit confused... In my sysroot directory for my target (i.mx6) I have Qt in version 5.2.1 and Qt3D libs with Version 5.3.0. Those Qt 3D libs are not officially-provided by the Qt Project, and they're incomplete. Perhaps you can ask the person who built those libs? I already tried to build the Qt3d 5.5 version with my Qt 5.2.1 dev enviroment, but it doesn't work. Why not? What errors do you get?

Call configure with -v, you should have some more details on what fails

Turns out this was a threading issue. The object that contained my QAbstractTableModel-derived models had been moved to a worker thread, which doesn't work well with the model/view architecture - both the GUI thread and the worker thread were sending signals to the models, which meant that insert row and remove row operations were overlapping each other, hence the odd behaviour. The main take-out is: when using the model/view approach, the models must have the same thread affinity as the views (i.e. keep the models on the main application thread); don't move them to worker threads unless you want to get jiggy with serialising access.
