Quick reminder: Qt 5.15.5 has been released; Users of this package will need to rebuild qt5-styleplugins (yay -S --rebuild qt5-styleplugins), otherwise Qt applications will crash.

The pkgrel of this package has been bumped so this should be done automatically by your AUR helper.

Note that building with a polluted path or library path can cause this package to fail to build. For example,

/usr/bin/ld.gold: error: cannot open /home/samueldy/miniconda3/envs/python-email/bin/../x86_64-conda_cos6-linux-gnu/sysroot/usr/lib64/libGL.so: No such file or directory

This happens because I tried to build in a shell with a Conda environment activated.

@JPenuchot: Thanks! Added this hook since it will hopefully reduce the amount of confusion whenever Qt updates.

Thanks for the bump! By the way, maybe a notification hook similar to this could be added?

@miskanera, @q234rty: pkgrel bumped, which will trigger a rebuild that fixes the crashes with the new Qt version

After upgrading to qt 5.15.5, some programs stopped running unless qt5-styleplugins was removed.

Well, it's time to bump again :D

Tried to compile, but failed with:

qgtk2dialoghelpers.cpp:46:10: fatal error: gtk/gtk.h: No such file or directory 46 | #include <gtk/gtk.h>

gtk2 and gtk3 are installed...

@patrick96: done

@yrlf Could you bump the pkgrel to force all AUR helpers to rebuild the package? This will save a lot of people a lot of headache.

Qt 5.15.3 has been released. As stated in the pinned comment, you will need to rebuild this package or Qt applications will crash.

Hi,

I suggest to make this a split package: build once, but package the base and a qt5-styleplugins-gtk2 separately.

The latter should contain:

• usr/lib/qt/plugins/styles/libqgtk2style.so
• usr/lib/qt/plugins/platformthemes/libqgtk2.so
• usr/lib/cmake/Qt5Widgets/Qt5Widgets_QGtk2StylePlugin.cmake
• usr/lib/cmake/Qt5Gui/Qt5Gui_QGtk2ThemePlugin.cmake

Because gtk2 is not mandatory for the base library to work, only for the above-mentioned optional additions.

If you split this package, the -gtk2 one can be optional for the main package.

Also in this case, gtk2 should be a makedepend for the base package, and a normal depend for the -gtk2 subpackage.

I think that there might be a race condition somewhere, or a shell invocation issue. I had an issue with the first build attempt (clean environment, so the --rebuild shouldn't have been needed to get around the QT package update) and I got a strange error from moc complaining about too many files.

But the odd thing was that it was in the bash session I called makepkg from, rather than a subshell. I could see the moc invocation from bash history, along with all the calls to gcc. The really weird part, was that the package was finished before the call to moc. I'll see if I can do some debugging on it next week, maybe my set up is weird.

Anyways, thanks for making this PKGBUILD, when it worked, its awesome.

An error occured while update:

error making: qt5-styleplugins

@Brottweiler: gcc is already assumed to be installed if you're building from AUR.

https://wiki.archlinux.org/index.php/Arch_User_Repository#Getting_started

"Ensure the base-devel package group is installed in full (pacman -S --needed base-devel)."

gcc needs to be makedepend

May I suggest you to add something like this in package():

_qtver=$(pkg-config --modversion Qt5Core)

depends+=("qt5-base=$_qtver")

This will stop the flood of bogus bug reports we're getting every time Qt is updated.

Can you make a pacman hook to trigger a rebuild when Qt updates, instead of requiring users to manually rebuild?

Please bump the pkgrel again, as qt5 is now at 5.15.2

Please bump the pkgrel if it needs a rebuild. The git log shows this has been done in the past.

Quick reminder: Qt 5.15.5 has been released; Users of this package will need to rebuild qt5-styleplugins (yay -S --rebuild qt5-styleplugins), otherwise Qt applications will crash.

The pkgrel of this package has been bumped so this should be done automatically by your AUR helper.

@SpacingBat3 done pal :)

This package is compatible with aarch64 architecture (at least I could built it successfully with "yay" package and select all of styles with qt5ct).

So my actual request is to add "aarch64" arch (with exact this name) to this package PKGBUILD, because it could be built without any problems. Some package managers like pamac (preinstalled with Manjaro) denies building progress while reading ARCH variable in PKGBUILD, making them harder to actually install and update.

@Ferdi265: Thanks, that worked beautifully!

@DAMO238: This exact error is what I experienced recently: https://bugs.archlinux.org/task/66805

The solution is to recompile qt5-styleplugins.

With an AUR helper like yay, this can be done with yay -S --rebuild qt5-styleplugins

When qt5ct is set to 'gtk2' and QT_QPA_PLATFORMTHEME=qt5ct, every qt5 application segfaults. The backtrace is in the following gist: https://gist.github.com/DAMO238/670e5554d41a15a27aebd393f8b792af. It looks like an infinite recursion error to me (although I'm no expert in these things). I have also tried using the git version to no avail.

ferdi thanks for patching this again mate :)

@gamezelda: I noticed that too, but I initially thought it was a bug in qt5ct, so I patched it there via an ugly workaround that I didn't upstream because I was sure it wasn't the real source of the problem.

Thank you for tracking that down! I'll integrate your patch into the package.

Edit: I can't really reproduce your problem any more by downgrading to older versions of qt5-styleplugins, but I definitely experienced the same ugliness with keepassxc (I use a light theme, but the difference in background color was still apparent)

Edit2: I can reproduce your problem with qt5ct-0.41-3 and qt5-styleplugins-5.0.0.20170311-21, and your patch definitely fixes it. It's just that the qt5ct guys apparently also fixed it. Here's their patch: https://git.archlinux.org/svntogit/community.git/tree/trunk/qt5.15-palette.patch?h=packages/qt5ct&id=ef7a6058bf79f1dbab8732838da5e956c51a6e5f

Qt 5.15 just got out of testing and after the upgrade (and even after recompiling this package), keepassxc looks ugly for me (I use a dark theme for GTK, and keepassxc looks like it's using a mix of a dark and a light theme)

I took a look at the patch for Qt 5.15 in this package and the related change in Qt ( https://github.com/qt/qtbase/commit/0a93db4d82c051164923a10e4382b12de9049b45#diff-8351cff715fd685cdf3fb01282c40529L1423 ) and tried changing the (now non-existing) call to QApplicationPrivate::setSystemPalette to QApplication::setPalette instead of deleting it (like this: https://pastebin.com/x4Uf4tVi ), since that's pretty much what QApplicationPrivate::setSystemPalette did, and this has solved my immediate issue with keepassxc. Not sure if that's the 'right' fix or there's any gotcha, though.

thanks I have updated the pkgbuild

This package fails to build once Qt 5.15 lands (currently in testing).

This patch from the OpenSUSE team fixes the build:
