Failing to emerge some kde-apps that worked before

[guicoelho]

Hello everyone,

Recently I was updating @world, which was cancelled because some kde-apps could not be compiled. Basically it is all these ones:

Code: Select all

 *  (kde-apps/kteatime-25.08.3:6/6::gentoo, ebuild scheduled for merge), Log file:

 *   '/var/tmp/portage/kde-plasma/spectacle-6.5.3/temp/build.log'
 *  (kde-apps/konsole-25.08.3:6/6::gentoo, ebuild scheduled for merge), Log file:

 *  (kde-apps/dolphin-25.08.3:6/6::gentoo, ebuild scheduled for merge), Log file:
 *   '/var/tmp/portage/kde-apps/dolphin-25.08.3/temp/build.log'
 *  (kde-frameworks/ktexteditor-6.20.0:6/6.20::gentoo, ebuild scheduled for merge), Log file:
 *   '/var/tmp/portage/kde-frameworks/ktexteditor-6.20.0/temp/build.log'

And also, the system keeps asking the to do an emerge @preserved-rebuild for these two:

Code: Select all

!!! existing preserved libs:
>>> package: kde-apps/kate-lib-25.08.3
 *  - /usr/lib64/libkateprivate.so.25.08.2
 *      used by /usr/bin/kate (kde-apps/kate-25.08.2)
 *      used by /usr/bin/kwrite (kde-apps/kwrite-25.08.2)
Use emerge @preserved-rebuild to rebuild packages using these libraries

I'm not sure what to do to solve this... I'm going to attach /var/tmp/portage/kde-apps/kate/temp/build.log but it seems it all boils down to an "undefined reference to `QObjectPrivate::QObjectPrivate(int)@Qt_6_PRIVATE_API" error that brings the error to compile.

I made the full build.log available here, I can upload other logs if anyone thinks it is important... by myself I can't figure out why it is throwing these errors.

Moved from Desktop Environments to Portage & Programming.

Moved from Desktop Environments to Portage & Programming.

Thanks and also sorry for the mistake.

[dmpogo]

what I would have done is unmerge kate, and try to update the world after that


Your first block of code does not contain useful info, since it does not show what was the error.

[Moe79]

@guicoelho: Did you solve this problem? I'm having the exact same issue since today

edit: after manually updating qtspeech with

Code: Select all

emerge --oneshot qtspeech

everything works again

[guicoelho]

Hello, sorry for taking a few days to answer. It turns out that deselecting:

kde-apps-meta
kate
kwrite

Then I unmerged all these three packages and updated the world. After that, I could just re-select the three packages and they were build successfully. Not sure why they were throwing errors before, but I'm glad it worked! Thanks for the tip, dmpogo.

You can edit the first post and add solved somewhere in the title.

I understand that the OP has resolved this, but is this not actually a bug, with packages building in the wrong order? My reading of the error is that there is a Qt6 symbol which is missing in the installed libraries, but is then available in the updated libraries once those packages have been merged. This then permits the kde packages merging correctly. It suggests a missing dependency in the kde packages?[/code]
I have hit this issue, and I am now updating the Qt6 packages which are tagged for updating before running the world build again.
These are the packages affected:

Code: Select all

[U] dev-qt/qtimageformats
[U] dev-qt/qtmultimedia
[U] dev-qt/qtspeech
[U] dev-qt/qtwayland
[U] dev-qt/qtwebengine
[U] dev-qt/qtwebview

I am trying to do it without building the qtweb* packages first, as these take ages to build!

[Hu]

I don't think it's that they're built in the wrong order, but it does seem wrong that this can happen. I suspect what happened is:

• OP used emerge --getbinpkg or similar to install a qtspeech:6 that needs a >=qtcore-6.N (for some N that I don't know)
• OP had a qtcore version 6.M for M < N, where the required symbol did not exist
• There was no RDEPEND on qtspeech to force Portage to update qtcore, so no update was done during the emerge --getbinpkg phase.
• Since OP's version M was too old, qtspeech was broken until qtbase was updated to version N. Kate happened to be the first package to fail due to qtspeech being broken, but I think qtspeech was generally unusable on OP's system at that point. I expect nothing that linked to Qtspeech worked until this was fixed.

Generally, the Qt packages are supposed to be updated as a group and kept at the same version. In my experience, Portage is very reluctant to let you get them out of sync. If someone can get into this scenario without bypassing any of Portage's normal dependency rules, I think it would be interesting to explore why Portage allowed that.

Hi Hu - thanks for the quick comments!

So, another data point: In my case, the system builds everything (no binpkgs), and is regularly updated. The failure occurred in the middle of a world update, and I believe several Qt packages had already updated, but when the kde packages failed, the Qt packages listed above had not yet been updated.

Anyway, I will report back when I get through the build.
