Yep, thanks. Merged/fixed now apparently.

Next issue with qwt:

[344/2107] Building CXX object src/gui/CMakeFiles/qgis_gui.dir/qgis_gui_autogen/mocs_compilation.cpp.o

Not sure if this has something to do with my qwt install from experimental/sid:

libqwt-qt6-6.2/now 6.2.0-1 amd64 [installed,local]
   Qt widgets library for technical applications (runtime, qt6)

I think the version is more or less in line with my qt6 from testing/trixie?

pyqt6-dev/testing,now 6.6.1-2 all [installed]
   development files for PyQt6
libqt6core6/testing,now 6.4.2+dfsg-21 amd64 [installed,automatic]
   Qt 6 core module

Any hint to overcome this one?

Regards,

Richard Duivenvoorde

PS: let me know if this is totally not helpful, I'm just eager to know if QGIS-qt6 is building (or I can make it build) on Debian testing/trixie
