Question #516
Description
I am trying to update from Qt5.15 to Qt6.8. We are using gcc 11. I downloaded the latest QtNodes a couple of days ago. I'm having a problem building QtNodes. I don't know if the problem is within QtNodes, Qt, or some symbol or option set wrong. I'm getting hundreds of errors that look like this:

As near as I can tell online, there was a change in Qt6 that required a code change in programs that use Qt6. I don't see any indication that that was done for QtNodes.
Any suggestions or help would be appreciated. Thanks
