QT software broken after some main libs, [temp resolved]

Anyone else? This updates from 40m a go broke all my QT applications for example:
- qutebrowser
- qtgreet
.... etc.

```
[2024-11-07T21:58:52+0100] [ALPM] upgraded x265 (3.6-1 -> 4.0-1)
[2024-11-07T21:58:55+0100] [ALPM] upgraded qt5-webengine (5.15.18-1 -> 5.15.18-2)
[2024-11-07T21:58:55+0100] [ALPM] upgraded qt6-multimedia-ffmpeg (6.8.0-1 -> 6.8.0-2)
[2024-11-07T21:58:55+0100] [ALPM] upgraded qt6-multimedia (6.8.0-1 -> 6.8.0-2)
[2024-11-07T21:58:58+0100] [ALPM] upgraded qt6-webengine (6.8.0-7 -> 6.8.0-8)
```

Hoping this was just a miss/error on the devs side to release libs without making sure dependencies are build against them etc.
will keep trying, see if we get updated software that works with the new versions.
Just basically wondering if other people see this issue.

Happy Hacking

Re: QT software broken after some main libs, [temp resolved]

qtgreet is an AUR package and so is your ffmpeg-obs fork

Sidenote, please use [code][/code] tags, BBS predates markdown by 20 years or so.

Updating/rebuilding aur packages is your responsibility.

Moving to AUR Issues, Discussion & PKGBUILD Requests.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: QT software broken after some main libs, [temp resolved]

Thanks, okis.
looks like they both depend on libx265.so.209

qtgreet
qtgreet: error while loading shared libraries: libx265.so.209: cannot open shared object file: No such file or directory

but I have installed after the above update:

locate libx265.so
/usr/lib/libx265.so
/usr/lib/libx265.so.212

PD: haha sorry about the markdown comes out naturally.

Re: QT software broken after some main libs, [temp resolved]

Update, compiling for -git did not work, error out. So I know it is not good to create symlinks, but I did it temporary to see if more libs are involved and indeed there are more... so going to have to just wait for a release

qtgreet
qtgreet: error while loading shared libraries: librubberband.so.2: cannot open shared object file: No such file or directory

locate librubberband.so
/usr/lib/librubberband.so
/usr/lib/librubberband.so.3
/usr/lib/librubberband.so.3.0.0

[update]
- obs  also broken.

obs
obs: symbol lookup error: /usr/lib/libavcodec.so.61: undefined symbol: x265_api_get_209

[update2]
Temp fix by installing main repo ffmpeg instead of AUR ffmpeg-obs
greetd and most QT apps now works, but of course now I will have the OBS issues but I can live with that until maintainer of ffmpeg-obs update what is needed.

Re: QT software broken after some main libs, [temp resolved]

What -git package in particular failed to build. What was the output from makepkg for that build failure?
