I'm working on a info screen application done in Qml that will be run on a Raspberry Pi. I'm doing the main coding on the desktop and everything runs well.
On the Pi I'm using a self build of Qt 5.4.2 and it worked very well, until yesterday that is. Suddenly I got no display of my info slides. Strange thing, it worked perfeclt fine before.
After a good bit of cursing I found that my Image didn't show, because for some odd reason the binding of
was evaluated as false. Well, how the hell is that possible was the next question. And debug output of the state randomly said "undefined", eh ?? WTF!?
What I don't understand is how it suddenly crept up as I've used states before too in my app. Anyway, it turns out that it is a known bug (QTBUG-41649) in gcc-4.6 on arm that miss compiles a specific file in the Qml library.
Fix applied and all seems well. I hope.
