Building the Plasma6 for Slackware-current in the KTown style - a build based on the AlienBOB's KTown

gmgf · 05-22-2024, 12:53 PM

kdevelop, compile with qt5, only if you uninstall the latest package 'libksysguard' before, because, it is compiled with qt6, another solution, make one package 'libksysguard-5' for qt5 the latest version for qt5, is in slack-current.

Non problem here with cervisia it compile with qt5.

gmgf · 05-22-2024, 01:22 PM

for 'cervisia', try compile the package 'kio-5' like this in one cmake/kio-5 file:

mkdir cmake-build
cd cmake-build
cmake \
"${KDE_BUILD_ARGS[@]}" \
"${KDE_QT5_ARGS[@]}" \
$KDE_OPT_ARGS \
-DKF6_COMPAT_BUILD=ON \
..

and try to rebuild 'cervisia'

I have added another package in my ktown 'kio-extra-kf5' the src is here:

https://download.kde.org/stable/rele...24.02.2.tar.xz

it's one dep of kdevelop,

another solution make one kio-extras-5 package with kio-extras-24.02.2.tar.xz

After the latest update (Wed May 22 18:57:13 UTC 2024) I no longer can open a Plasma session on Wayland. Opening using "Plasma X11" is still OK.

EDIT: even on a Plasma X11 session, the desktop is unstable. KWin crashes frequently to the point that the desktop is not usable. I have to resort to XFce.

This is due qt6-6.7.1_20240516_6977d02f upgrade. Three choices here:

Downgrade to qt6-6.6.3_20240319_c2516323
Recompile your entire plasma6 stack against new qt6-6.7.1
Wait for the plasma6 packages provider to recompile the entire stack against new qt6-6.7.1

If you want try it.
First clean your /tmp from any *.t?z
Then to build all kde command

Code:

slackpkg_build kde

it will download it in /tmp/slackpkg_buil/kde
then you can cd there and run kde.SlackBuild
when it finish

Code:

upgradepkg --reinstall /tmp/*.t?z

PS. Note that it will some time to build all kde i never tried this...
I mostly use it to rebuild a package from source...for special reasons...

It is about Plasma6 which is built by LuckyCyborg. These packages and their sources are only available as large tarballs.

I don't think this slackpkg_build can be useful when it comes to a KTown-style source tree, which is available in a big tarball uploaded to Mega.

It seems that we are facing a classic problem that even the original KTown had.

To help then can in -current appear updates that affect KTown packages (or those in his style), Mr. Hameleers maintains a number of -compat packages:

https://taper.alienbase.nl/people/al.../boost-compat/
https://taper.alienbase.nl/people/al.../icu4c-compat/
https://taper.alienbase.nl/people/al...oppler-compat/

I warmly recommend the use of these three -compat packages by those who use this build of Plasma6, because they were very useful even when Plasma5 was in KTown.

yes you are right i deleted my post. sorry.

Another suggestion I have for those who use packages built by LuckyCyborg, is that (just like when Plasma5 was in KTown) to carefully inspect the ChangeLog and if you find packages that you believe can affect Plasma6, to wait for updates to be available from his side. For example, a Qt-6.6.3 update to Qt-6.7.1 is a recipe for disaster.

And here an important note must be made: he does not have at his disposal computers as powerful as many in this forum. And above all, he uses a 3G mobile Internet connection, which is particularly slow in the case of uploads.

This means that you will have to be patient to have updates available, especially when it comes to a full rebuild.

Unfortunately, this is the truth. LuckyCyborg does not have the same high-performance logistics as many of you.

Correct. I downgraded qt6 to the previous version and everything went back to normal. Thanks!!

You may want to also downgrade poppler, otherway okular won't be able to open PDFs, even with the poppler-compat package installed.

Had no trouble opening PDFs with okular after upgrading to the latest poppler-compat from AlienBob.

EDIT: nevermind, today I couldn't open anything. Had to resort to @denydias' workaround.

Indeed. Okular outputs this when trying to load a PDF:

Code:

kf.coreaddons: "Could not load plugin from /usr/lib64/qt6/plugins/okular_generators/okularGenerator_poppler.so: Could not load library from /usr/lib64/qt6/plugins/okular_generators/okularGenerator_poppler.so: (/usr/lib64/libQt6Core.so.6: version `Qt_6.7' not found (required by /usr/lib64/libpoppler-qt6.so.3))"
org.kde.okular.core: Failed to load plugin "/usr/lib64/qt6/plugins/okular_generators/okularGenerator_poppler.so": "Could not load plugin from /usr/lib64/qt6/plugins/okular_generators/okularGenerator_poppler.so: Não foi possível carregar a biblioteca /usr/lib64/qt6/plugins/okular_generators/okularGenerator_poppler.so: (/usr/lib64/libQt6Core.so.6: version `Qt_6.7' not found (required by /usr/lib64/libpoppler-qt6.so.3))"

The upgraded poppler-24.05.0 is also compiled against qt6-6.7.1, so it complains about the version mismatch. That's why poppler-compat doesn't help on this case as it's also built with new qt6 in place.

Downgrading to poppler-24.04.0 workaround the issue for now.

As a side note, blacklist (slackpkg) or greylist (slackpkg+) these sensible packages also helps here.
