Irrlicht Engine

qt no longer works with irrlicht in SVN branch

Do you have any more info? Are there compile-bugs? Does anything behave wrong - like does it not render anymore?

application just crashes, its fairly new within last month

You don't know the line where it crashes? Or have some example?
Is this on Windows?

https://github.com/netpipe/IrrlichtDemo ... aster/GUIs the qt demo's from here do it also my cannachat client https://github.com/netpipe/cannachat this was on linux would suspect its same for windows.

OK, guess I have to try to set up a Qt environment to test (I never used the combination of Irrlicht + Qt before). Will probably take a bit. I hope the qtIrrlicht in your examples will allow to reproduce it. I see .pro files in there - are you using that? With QtCreator or direclty with qmake?

compiles with qmake and qtcreator. you might have to change the .pro file to reflect your lib paths

OK, thanks.

irrlicht svn does not have it working still, i might have to look too now.

Yeah, still on my todo (still have to get the examples running on Linux. Sorry, little experience with Qt/qmake on Linux so I might have lost motivation a bit too quickly on that).

OK, I tried again today. Unfortunately so far no success in reproducing a crash.

I used your example IrrlichtDemos/GUIs/qtIrrlicht. Result is a close-up rendering of an animated 3d figure (which looks a bit strange because camera is half in the model). And X11 errors (GLXBadDrawable) because there seems to be a second device started with burnings renderer which somehow doesn't work like that.
But I did go back until revision r6008 (which is half a year old) and the behaviour was exactly the same.

JLouisB also did some test recently on Windows and also didn't get any crashes.

So either that example works or it's something which I can't reproduce with my Qt version here (Debian stable system which has probably Qt5.11.3).

I thought a bit about what could cause the troubles for you. A bit older than you suspect, but one change which can maybe cause troubles is that X11 currently no longer has resizable windows by default (which may change again before release, especially if that causes the problem here). To check if that is your bug please add set WindowResizable in SIrrlichtCreationParams (the parameter for createDeviceEx) to true for testing.
