I also must exclude the QMacPasteboardMimeGraphics class in 
GuiApplication.cpp since QMacPasteboard is not available anymore with qt6.


and add an #include  in support/Package.cpp (I suppose 
this will pose no problem for qt5 but have not checked it, it's only

I have build successfully with the latest LyX and with Qt6 and cmake. 
There are a few issues to take into account:


1) there is an incompatibility between the moc_ files generated with qt5 
and qt6; you must remove these files manually if you switch; a "Clean" 
within XCode is not enough.


2) qtmacextras is not included in qt6 (it's not clear whether it ever 
will). You must remove 2 steps in the cmake files and the 
QMacPasteboardMimeGraphics code in GuiApplication.cpp.


3) I had to add one #include  in support/Package.cpp.

I believe the qtmacextras is needed for copy/paste (and dragging) .pdf 
content.


P. De Visschere



I found this in the qt-wiki:


Qt Mac Extras

Not included in Qt 6.0. Will find new home in the more relevant modules 
over time, and the remaining APIs considered included in later 6.x releases.



So, some time qt6macextras should be back.

Try calling cmake with '-DLYX_USE_QT=QT6'
(or, in the GUI, select LYX_USE_QT to QT6)

Configure should fail if QT6 is not complete.

1.) Have you tried a clean build? (Looks like you do not use moc6 but moc5)
2.) Are you able to use cmake to compile?

Error when compiling with Qt6 on macOS

[Christoph Schmitz]

I have tried to compile LyX with Qt6 on macOS. The compiler stops quickly after 
a series of error messages. I attach a complete log file of my configure and 
make run.

Compiling LyX with Qt5 works with charm (thanks to the help of Marcus Mikulcak).
