Bug ID: 467631
Summary: kguiaddons fails to build with qt6/kde6
Classification: Frameworks and Libraries
Product: frameworks-kguiaddons
Version: unspecified
Platform: Debian testing
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdelibs-b...@kde.org
Reporter: jingxuan....@gmail.com
Target Milestone: ---
SUMMARY
When running "kdesrc-build frameworks" (after: changing all configs to target
kf6-qt6 and building qt6 from source), compilation fails (even though
dependency checks seem to succeed).
STEPS TO REPRODUCE
1. On debian testing, setup kdesrc-build according to:
https://community.kde.org/Get_Involved/development and modify configs according
to (in order to build qt6 & target qt6/kde6):
https://community.kde.org/Get_Involved/development/More#Build_Qt6_using_kdesrc-build
2. Run "kdesrc-build qt6-set" to build and install qt6.
3. Reconfigure kdesrc-buildrc to build kf6 and plasma (instead of qt6)
4. Run "kdesrc-build frameworks"
OBSERVED RESULT
At step 11/79 of kdesrc-build frameworks ("Building kguiaddons from frameworks
(11/79)") , kdesrc-build outputs "Compiling... failed (after 1 second)
kguiaddons didn't build, stopping here.". Inspecting the error.log output of
kguiaddons gives us:
# kdesrc-build running: 'gmake' '-j' '16'

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian Testing with kdesrc-build targeting kf6-qt6 (Latest
Master/Main branch)
ADDITIONAL INFORMATION
Attempts to use the default qt6 packages shipped by debian testing have also
failed when using "kdesrc-build frameworks" at kwayland. It seems that qt6 as
shipped by debian testing is not complete for development (even if all
development packages are installed).
