state of QT6 and plans?

[Greg Troxel <gdt%lexort.com@localhost>]

Having just updated qgis to 3.44 (which will be the last qt5 LTR), I am
starting to look at qgis 3.99 (master, heading to 4.0 in February) which
uses qt6.  It's likely not going to be reasonable for normal use until
late 2026 at least.

My first step is building qgis from source outside of pkgsrc, using
pkgsrc dependencies.   I'm finding some things missing, and I wonder if
there is a grand plan, or someplace where we're keeping track of what
needs to be done.

I see in pkgsrc a number of qt6 packages.  There is a meta package, but
the DESCR doesn't lead me to understand if qgis should just depend on
the qt6 metapackage or on the list of things it really needs.  I'm
thinking the list, as surely much of it isn't necessary.

It looks like qwt is missing.

What do people think is on the todo list, or do people think we are
pretty much done?



The list of what we have now:

There is also wip/qt6-qtwebengine.  It seems to use a forked upstream,
and I can't tell what's going on.  So far, I don't think I need this for
qgis.
