Status of KDE Plasma

Status of KDE Plasma

[Anthony Wang]

[-- Attachment #1.1: Type: text/plain, Size: 620 bytes --]

Hello!

I'm a KDE contributor and free software enthusiast, and I recently started switching over some of my systems to GNU Guix. However, as an avid KDE Plasma user, I'm a bit disappointed that Plasma doesn't seem to be packaged for Guix. I did a bit of searching and found that there has been some progress towards packaging Plasma:
- https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/kde-plasma.scm
- https://lists.gnu.org/archive/html/guix-devel/2021-01/msg00426.html

I have a few questions: What is the current status of KDE Plasma on Guix? And also, how can I help or contribute?

Hi! I'm glad to see there's somebody interested in KDE packaging.

Z572 have done some work here, and make kwin available on Guix.
https://github.com/Z572/guix/tree/kwin

Currently I'm planning to upgrade Extra cmake modules from 2.70 to 2.91
in upcoming staging branch. This will help us to package a more recent
version of KDE packages.

Can you figure out a minimal set of packages needed to run Plasma
desktop? We can add a milestone and checklist about it.

I don't know about Plasma, but Hartmut Goebel has some repository with
updates & 100 extra KDE packages
<https://gitlab.digitalcourage.de/htgoebel/guix-kde-package>.
The idea is to move them into guix
<https://lists.gnu.org/r/guix-devel/2021-01/msg00426.html>.  I don't
know the current status of that.

Greetings,
Maxime.

referring back to the wiki discussion, this is a good example for the
kind of information that should be sitting on the KDE wiki page of
Guix. probably along a short summary of its status, and a list of
developers who expressed interest in working on packaging KDE.

such a page would greatly facilitate the cooperation/effectiveness of
the interested parties.  the ability to cheaply and dynamically spawn
a sub-mailing-list/comment-thread for such sub-projects would be icing
on the cake.

Build failure of extra-cmake-modules 5.91.0 (was: Status of KDE Plasma)

[Zhu Zihao]

[-- Attachment #1.1: Type: text/plain, Size: 1873 bytes --]


Hi.

I'm creating a patch that updates ECM to 5.91.0 but it failed the check.

The build log reports the KDEFetchTranslations test failed, with
following log

```

```

It says that the name of project should equal to
`frameworks/extra-cmake-modules`. But I don't see they set the project
name to `frameworks/extra-cmake-modules`.

I checked the package recipe of Archlinux and Nixpkgs, looks that they
don't have this issue.

WDYT?

I definitely agree that having a single place to coordinate all these efforts would be very beneficial since it seems to be currently spread out all over the place.

I also found the wip-kde-plasma branch in the Guix Git repository has some made some progress too. However, this branch has not been committed to in more than a year and only supports KDE 5.19.

Hello,

there is also this line:

Maybe this is the real error, and a dependency is missing? We do have a
package called appstream in Guix, and it contains the binary appstreamcli.
How about trying to add the package to native-inputs?

Hi,

glad to see someone to pick up this task.

You can find the current state of Plasma in the „wip-kde-plasma” branch 
<https://git.savannah.gnu.org/cgit/guix.git/tree/?h=wip-kde-plasma>.

The top-level directory contains a 00-README-Plasma.txt 
<https://git.savannah.gnu.org/cgit/guix.git/tree/00-README-Plasma.txt?h=wip-kde-plasma>, 
explaining the current state in detail. The branch also provides some 
helper-scripts for testing, etc. I strongly recommend reading through 
all of these files to find the hidden gems ;-)

Basically there are package definitions for most of the Plasma packages 
(as of 5.19), kwin, etc. One of the files has a list of state per 
package. Anyhow I failed to make Plasma start the actual desktop.

This branch intentionally is on 5.19, as the Readme says:

|Note 1: It might be worth making an older version of Plasma work, as 
this an older version has less dependencies. This is why this branch 
still sticks at 5.19.5. |

And to my experience Plama is a beast and taming it might be much easier 
when using a less beasty version. This is why I recommend sticking with 
this old version for now and update only after this works.

To emphasize this: Packaging the Plasma module is basically done. But 
making Plasma Desktop actually run is a major issue.
