Plasma-workspace build failing with kdesrc-build

randomletters · September 23, 2023, 4:07am

I’m using the development iso in a VirtualBox VM (host OS Windows) to build KDE Plasma (as described in the docs: (for some reason, I can’t attach a link to this host, so I’m omitting an “h”: ttps://community.kde.org/Get_Involved/development/Build_software_with_kdesrc-build)):

However, while building plasma-workspace (the top-level package, not any of its dependencies), I encounter an error that I don’t know how to fix:

[3/1471] Building CXX object components/shellprivate/CMakeFiles/plasmashellprivateplugin.dir/widgetexplorer/w>

...

I’ve tried re-running the build and removing the build directory (multiple times, in various orders), but I still get the error (I’ve also tried googling it + asking ChatGPT, no luck). I don’t know why this error happens or how to fix it, so any ideas would be appreciated.
Here’s is the full log (if needed:

If you take a peek in your ~/kde/src/log/latest/plasma-workspace/cmake.log (or build.log, I don’t recall right now), is there any NOT FOUND message about KNewStuff? If so, including knewstuff to your kdesrc-build should work.

randomletters · September 24, 2023, 12:22am

Sorry for the late reply, but my build.log and error.log are identical, there’s no cmake.log, and I didn’t see anything glaringly obvious (or anything at all) about KNewStuff. Nevertheless, I’m running kdesrc-build knewstuff now, and will report back with any new information. Thanks for the idea!

edit: knewstuff installed, but plasma-workspace still does not build

I’d suggest uploading the full log to a paste service so the developers can see the full context/log.

randomletters · September 24, 2023, 2:30am

I’ve already uploaded the (I believe) relevant build.log (which is identical to the error.log) in my first post, and I don’t know where to find the full build log - any suggestions?

Justin · September 24, 2023, 4:06am

Ah I missed it as it was folded.

randomletters · September 24, 2023, 4:22am

I can’t edit the original post (as far as I can tell) and that missing parenthesis is driving me out of my mind now (haha), but thanks for pointing that out - I’ll keep it in mind for the future!

Did you build it with kdesrc-build ?

By the way you can build plasma, with just kdesrc-build --include-dependencies plasma-desktop

I recommend you to build and install plasma-pa and plasma-nm to have audio and network management in you session.

randomletters · September 24, 2023, 5:51pm

Yes, I did. I’ve just tried running
kdesrc-build plasma-desktop plasma-nm plasma-pa --include-dependencies
but that leads to building plasma-workspace as package 81 of 93, which causes the build to fail with the same error.

meven · September 30, 2023, 12:24pm

Which branch are you building ?

Maybe you need to refresh the knewstuff library:
kdesrc-build --refresh-build knewstuff

Perhaps better talk directly:
