Description Mattia Verga 2023-07-03 18:29:04 UTC
As I tried to build a package (celestia) with QT6 and GLES I discovered that QT packaged in Fedora is built without GLES support.
Would it be possible to enable that?

Note that my only purpose of this request is because I think it could give better performances on ARM architecture, but I'm completely noob on this (and I even don't have an ARM platform where to test). So feel free to close/ignore this request if it is silly.

Reproducible: Always

This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.

Comment 2 Neal Gompa 2023-09-17 00:04:54 UTC
The tricky problem with Qt is that OpenGL vs OpenGL ES is mutually exclusive in Qt. Why? I have no idea.

Some distributions solve this problem by building Qt twice to get both variants available and make it swappable. I don't know if that's the approach we want to take here, though...

Comment 3 Kevin Kofler 2023-09-17 22:17:09 UTC
And FYI, Manjaro ARM had done exactly that (well, they inherited the OpenGL builds from Arch Linux ARM and added their own OpenGL ES ones), but just a few days ago decided to discontinue the GLES builds. (They also never had GLES builds for Qt 6, only Qt 5.)

See:

https://forum.manjaro.org/t/arm-stable-update-2023-09-10-kernel-phosh-libreoffice-firefox-systemd/147726

> We removed all Qt5-ES packages

So I am not convinced adding Qt GLES packages is something we want to do in Fedora. It also mainly helps proprietary drivers (which for embedded devices tend to have no or broken desktop OpenGL support), FOSS drivers support desktop OpenGL just fine on embedded devices, maybe slightly slower than OpenGL ES, but it works.

This message is a reminder that Fedora Linux 39 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 39 on 2024-11-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '39'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 39 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 5 Aoife Moloney 2024-11-27 21:14:28 UTC
Fedora Linux 39 entered end-of-life (EOL) status on 2024-11-26.

Fedora Linux 39 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
