[QGIS-Developer] Qt6 builds and plugins -- ready for testing!

Sun Jan 28 03:32:27 PST 2024

Ok, lift off :-) See screenie.

Thank Even, I had mixed version qwt headers and libs.

So on Debian Trixie, there seems no libqwt for qt6 available yet?
Had to pull these from experimental:

libqwt-headers_6.2.0-1_amd64.deb
libqwt-qt6-6.2_6.2.0-1_amd64.deb
libqwt-qt6-dev_6.2.0-1_amd64.deb

Then QGIS-qt6 compiles and I can run it, without python though, because creation of the bindings fails.

Not sure if this is because of the libqwt in my setup or something else.
Also not sure if these are warnings, or the actual cause of stopping:

pyproject.toml: line 7: using '[tool.sip.metadata]' to specify the project metadata is deprecated and will be removed in SIP v7.0.0, use '[project]' instead
Querying qmake about your Qt installation...
These bindings will be built: gui.
Generating the gui bindings...

Regards & Thanks,

PS: slightly disappointed because QGIS looks exactly the same in qt6 :-) Was hoping that... don't know, would look very shiny now ;-)
