Description Cyril Levet 2021-04-17 01:34:23 CEST

Description of problem: Fetching project controled by VCS is not possible on DE other than KDE because KDE_FULL_SESSION=true is not set. 

When you click on Project -> Fetch Project on kdevelpo, it normally gives you a window for selecting the source (Git, Bazaar...). But in all DE except Plasma it directly show the Open Window. So you cannot import project.

This happens because KDE_FULL_SESSION has to be true and its not set in DE others than Plasma

This bug affects Mageia 8 too

Version-Release number of selected component (if applicable): kdevelop-5.6.2-3


How reproducible: Always


Steps to Reproduce:
1. Install Kdevelop on any DE except Plasma
2. Go to Project -> Fetch Project

Hi, thanks for this report and useful workaround.


Unsure if this an upstream issue or a by-design issue. KDE umbrella applications should be run in a Plasma/KDE session.
Perhaps a missing dependancy?

Assigning to KDE maintainers.

Comment 2 Nicolas Lécureuil 2021-04-20 20:27:11 CEST

can you do this in a terminal ? ( like konsole ).

This will allow to see debug/error messages.

If you install now qtxmlpatterns5 and konsole, kdevelop runs?

The problem is not that kdevelops does not run but that it is impossible to fetch a project because a window is not displayed if KDE_FULL_SESSION is not true.

Comment 7 David GEIGER 2021-04-23 21:36:23 CEST

kdevelop is developed for kde platform so I don't know if it can properly run/work under another platforms.

Comment 8 Cyril Levet 2021-04-23 21:48:22 CEST

Well in their website (https://www.kdevelop.org/), the first phrase is : KDevelop - A cross-platform IDE for C, C++, Python, QML/JavaScript and PHP. Working only on KDE is not really Cross-Platform. And the only thing that change everything is this environment variable :  KDE_FULL_SESSION. So I can use it on any other DE if I manually set this variable, but I don't know if it can be problematic to set it to true.

To finish paraphrazing:

KDevelop is a feature-full, plugin extensible IDE for C/C++ and many other programming languages. Supported platforms include Linux, Solaris, FreeBSD, macOS and other Unix flavors as well as Microsoft Windows. It is based on KDevelop Platform (kdevplatform), the KDE Frameworks and the Qt libraries.

It is cross platform to run on Linux, Solaris, FreeBSD, macOS and Windows. But as long as it is based upon QT AND KDE Frameworks, it requires the full Plasma Desktop to run.

Closing WONTFIX.
