Hi @EkkaratPrasongsap ,
I reached out to Qt Support regarding this issue and got a reply. It turns out that the version of Qt that we build against defines this symbol (as you know), but different versions of Qt either provided by package managers or built locally with different compilers do not define this symbol (as you're seeing when you build it locally).
This puts us in a difficult situation since we are building against the "official" qt release binaries provided by The Qt Company, but developers like yourself aren't able to use our software.
My recommendation for now is to use the binaries provided directly from The Qt Company via their installer if you can. That should alleviate the problem for you. Short of that, you could include a source file that implements this symbol (annotated to resolve the error) in your code, but that is a last resort and I would not recommend it if you can avoid it.
