Important: If you are having troubles compiling or launching YACReader and libicuuc is part of the error message, you need to rebuild libpdfium!

@beki, @taivlam: I removed the qt6-quickcontrols2 dependency from the PKGBUILD. All you need to do is get the latest version and build/install. Functionally it is the same as qt6-quickcontrols2 is now a part of the qt6-declarative package.

@beki I had the same "qt6-quickcontrols2 is missing" issue, but then I remembered that I needed to rebuild the dependency libpdfium, which fixed the issue (- c.f. the pinned comment).

(Somehow, despite the name being for a stable point release source package, it is more akin to a VCS package, as libpdfium can be rebuilt to update it even when the pkgver and/or pkgrel numbers haven't been incremented.)

@Aftershock9009 sorry I am facing the same problem. Can you be more specific about how to solve it please?

qt6-quickcontrols2 has been removed.

Tried to update my system today and got:

error: failed to prepare transaction (could not satisfy dependencies)
:: installing qt6-declarative (6.7.3-2) breaks dependency 'qt6-quickcontrols2' required by yacreader

Just switching those 2 on the PKGBUILD and compiling again fixed it.

After latest package upgrade (pacman -Syu), in GNOME Wayland, YACReader is stuck without window after starting up. The process itself does not exit, but there is simply no window being shown.

Some observations: If I switch to GNOME Xorg, YACReader run normally without error. There are no logs from stdout and stderr, simply nothing. If I run YACReader with strace, got:

After that, the poll is repeated infinitely. I guess this poll is normal, but I don't have any clue anymore other than this.

Some attempt to solve that I've tried: Tried rebuilding libpdfium and YACReader, still not solved. Tried removing xdg-desktop-portal and xdg-desktop-portal-gtk as suggested in https://bbs.archlinux.org/viewtopic.php?id=262897 , still not solved. Tried removing home .cache folder, still not solved

Personally, I think the problem reside in GNOME Wayland.

Any suggestion to solve this?

@afawfafawe: qt6-shadertools is a dependency of qt6-5compat, so it is implecitely satisfied.

I think add qt6-shadertools to dependencies will be necessary.

@rfox that happened to everyone who have build libpdfium when icu was at version 72, no need to report, just rebuild

I was also running in to a linker issue:

I rebuilt libpdfium-nojs, which allowed me to build yacreader.
