'QXmppPubSubBaseItem': an undefined class is not allowed as an argument to compiler intrinsic type trait '__is_trivially_constructible'

Hi everyone, I'm trying to compile the master branch of this project on Windows 10 64 bits. Here is my setup:

• Qt 6.5.2
• Visual studio code 1.81.1
• MSVC C++ amd64 17.6.5

Here are the compiling errors:

I have tried that on linux with GCC and apparently GCC is more flexible concerning the usage of templates on an incomplete type. Thanks in advance for your help, Rhylx

I've tried to use the stable version and it worked. I guess master is still work in progress for windows.

@Rhylx Does the current master branch work?
