Qt QML and C++ for embedded Linux Targets

[anda_skoa]

Sorry I didn't get this part. What's that supposed to mean?

It means if you want to use QtQuick as the UI technology, then you have to use QML as the language to describe the scene.
The original question was if QML was a requirement for Qt embedded programming. It is not, it is just a requirement for using QtQuick.

Can I use QML with Qt4.8.6 (which is by the way the last version of Qt4, IIRC) ?

Yes, QML (and QtQuick) was introduced in 4.7

Cheers,
