Hello,
I've been also working on this during a few times ago for a tutorial
that I've never achieved:
https://preview-pullrequest-1211--geotribu-preprod.netlify.app/articles/2024/2024-10-29_tester-qgis-4-futur-sig-open-source/#__code_1.
The content is in French but QWT code is international ;).
Hope it helps.
Regards,
Julien

Hi,
I would like to start compiling QGIS with Qt6 on Ubuntu. I've looked
into .docker/qgis3-qt6-build-deps.dockerfile, but the rules are for
fedora.
Currently, I'm missing libqwt-qt6 package on Ubuntu. I have the former
qwt-qt5 packages, but not the new qwt-qt6 ones.
dpkg -l | grep qwt
ii libqwt-qt5-6
ii libqwt-qt5-dev
I've found this:
https://packages.debian.org/experimental/libqwt-qt6-dev (and
libqwt-qt6-6.2). These ones are not easy to install, due to missing
dependencies.
Are these packages for qt6 available for Ubuntu for download on some
ppa or should I build them locally? Does anyone succeed with compiling
QGIS with Qt6 on Ubuntu?
Regards,
Jorge
