Wait one year...

Houston, we have a problem!!!!!

Standard support for Qt 5.15 will end after 26th of May 2025, as communicated earlier. After the support period, the release will be in EoS (End of Support) state and will only be supported through additional services, including Extended Security Maintenance for Qt 5.15, Extended Support, and Professional Services. Customers distributing applications and embedded devices using Qt 5.15 software should evaluate how to access technical support and maintenance patches which may include security fixes. Standard commercials terms still apply after End of Support.

Qt5 is now declared deprecated in Gentoo
At this point in time, Linux distributions are starting to track which packages are blocking a future Qt5 cleanup. Real Qt Company OSS support stopped back in 2020, when public availability of LTS releases started to be delayed for 1 year, stable branch repository access got closed down (with 5.15 branch repository receiving any new LTS tag one year after commercial release) and only Qt6-relevant bugs are being fixed (then backported) since then. The final release happened on 2025-05-19, which means a) we will not get it until 2026-06-19, b) any bugs discovered since last May will not be fixed and c) no bugs since 2020-12-08 that haven't also been affecting Qt6 were fixed at all.

Re: Nouveautés de la version de développement 0.9

Hi Laurent,

I have wanted to try and spend some time contributing to the main QET program, in addition to dxf2elmt (which I need to get back and do some work on).

Are there a specific set of Issues in the Mantis tracker related to getting things working in Qt 6 I could look at or start working on? I'm not real familiar with Mantis, but doing a quick search for Qt 6 I didn't find anything.

Would I just be better off attempting to compile it with Qt6, see what breaks and go from there?

Hi Vadoola,

this has only been reported here on the forum and on Github issues; there doesn't seem to be any entry in Mantis.

Emil have writted a new documentation for compile it under Windows with Qt6.9 if some one can try?
https://github.com/EmilOsvoll/qelectrot … d_Guide.md

As indicated by plc-user, the master and qt6-cmake branches have diverged significantly. Merging the master branch into the qt6-cmake branch causes many conflicts that must be resolved manually. I tried, but I got confused... my knowledge of GIT is limited.

Thanks this gives me a place to start looking.

I'll give it a go. While I'm not a fan of Windows, unfortunately my work laptop is running Windows 11. While I haven't done any in a while, I do have it set up for Qt development, so hopefully it won't be too much trouble to get it compiling.

I'm certainly not a git expert either, but I'll start by trying to get the existing qt6-cmake branch compiling, and then see what I can do from there.


Appreciate the help, hopefully I can get something useful going.

Re: Nouveautés de la version de développement 0.9

See Emil cmake files patchs, that can help you, I'm think.
