Libreoffice is capable of use qt6 if compiled with --enable-qt6

Could you compile it with this option? Thank you!

Feel free to apply the qt6.patch but the build fails due to earlier use of qt5:

[build CXX] vcl/qt6/QtFont.cxx
In file included from /build/libreoffice-fresh/src/libreoffice-7.4.3.2/vcl/qt6/../qt5/QtAccessibleWidget.cxx:21,
from /build/libreoffice-fresh/src/libreoffice-7.4.3.2/vcl/qt6/QtAccessibleWidget.cxx:10:
/build/libreoffice-fresh/src/libreoffice-7.4.3.2/workdir/CustomTarget/vcl/qt6/QtAccessibleWidget.moc:16:2: error: #error "This file was generated using the moc from 5.15.7. It"
16 | #error "This file was generated using the moc from 5.15.7. It"
| ^~~~~

I guess this can't be solved other than removing qt5 support. Qt6 vcl doesn't have a working video sink for GStreamer
so I prefer to leave out qt6 vcl for now until you find a way to solve the parallel build.

arojas: maybe you know a way how to fix this build error. There're no further important qt6 related commits in LO cgit. Maybe pending in its gerrit.

A possible workaround: compile with --enable-qt6 then make a separate package (i.e. libreoffice-fresh-qt6) with only the relevant file /usr/lib/libreoffice/program/libvclplug_qt6lo.so

(also I presume kf5 requirest qt5 too.)

A separate pkg is no option for the official repo. You can do a custom build disabling qt5 or push something to AUR.

This is actually Arch's fault due to our non-standard "no libexec" policy.

https://github.com/LibreOffice/core/blob/master/configure.ac#L13169

We should really rethink this policy. Nowadays libexec is officially part of FHS.

As a workaround, export qt6_libexec_dirs="/usr/lib/qt6" before autogen.sh
