Hey Dave,
You never cease to amaze! 'Helloworldgui' works here and console too. Only 10 days and you have a basic working QT6.... thanks heaps!
Thanks! To be honest, I didn't expect to get this far, this quick. I'd also expect that once we try and port some apps, that there will be problems, but we'll cross that bridge when we get to it.
I've now built:
QtDeclarative
QtMultimedia
QtShaderTools
QtSVG
QtTools
QtWebsockets
QtWebchannel
I've created a repo for QtWebEngine, and have created a set of diffs from the Qt 5.15.2 code, but haven't yet started moving over any OS2 specific files, nor adapting the changes in *.pri to CMakeLists.txt. A task for this week

Cheers,
Paul.
