Since version v1.7.0 the Qt5 backend is no longer actively maintained and supported.

Control environment variable can be used to force build against qt5

• ENABLE_QT5=1 to build against qt5 (default:off)

Usage cases:

• makepkg ENABLE_QT5=1
• yay -S openboard --mflags="ENABLE_QT5=1"

Yay users warning:

If you want to build against qt5, you have to call pacman -S qt5-{base,declarative,multimedia,tools,svg,webchannel,webengine} beforehand.

@unphysicalix: That's correct, you have to rebuild after dependency packages are updated. Let me make this post sticky to avoid people running into this again and again.

If OpenBoard stops working and when starting it from the command line you get an error message of the type:

openboard: error while loading shared libraries: *.so.1.1: cannot open shared object 

Then you most likely just need to rebuild OpenBoard (either with makepkg or with your favourite AUR helper) because a dependency package has been updated.

(That's the one disadvantage of AUR packages. I don't know what the threshold is for the package to be migrated into the community repository instead.)

@Andhika24kd You will have to rebuild OpenBoard to take the updated Poppler library into account. This was just discussed between iyanmv and bartus in the last comments, and the recommendation would be to use e.g. rebuild-detector to get notifications when AUR packages have to be rebuilt due to pacman -Syu updates.

Openboard complains about missing libpoppler.so.101 file but newer version (libpoppler.so.102) is already there. Is it the expected behaviour (using fixed version instead of the latest one)? Is there any workaround? Sorry but I'm kinda new to Linux.

@iyanmv: if you would like to pop pkgrel, be my guest :) But would rather propose using rebuild-retector to get notification upon pamcan -Sy about packages that need to be rebuild.

Once I've created an automatic update script with Travis for gimp-develop-git and won't bother again.

Would it be possible that when a rebuild is necessary, pkgrel is increased? I always discover that I need to rebuild when I need to use the app (in the middle of a video call) and compilation takes a bit...

@fsiegert I resolved it. See my edit. Sorry for the noise.

@pogojotz @woodchip That's weird, I still can't reproduce it. Unfortunately I don't know enough about the qmake build system here, so I don't understand why it doesn't find them if qt5-webkit is installed. Let me know if you figure anything out in your debugging.

@fsiegert I see exactly the same error. qt5-webkit is installed.

EDIT: Nevermind. I have a second Qt installation for work and have its bin path added to $PATH so the the line qmake OpenBoard.pro -spec linux-g++ used the wrong qmake version. I changed the line to /usr/bin/qmake OpenBoard.pro -spec linux-g++ now it compiles.

@woodchip It builds for me, so I'm a bit puzzled:

==> Starting build()...
Info: creating stash file /home/fsiegert/.cache/yay/openboard/src/OpenBoard-1.5.4/.qmake.stash
make -f Makefile.Release
make[1]: Entering directory '/home/fsiegert/.cache/yay/openboard/src/OpenBoard-1.5.4'
/usr/bin/uic src/web/browser/downloaditem.ui -o build/linux/release/ui/ui_downloaditem.h
[...]

Your message sounds a bit like qt5-webkit isn't installed, but that's a dependency, so you must have it installed, no?

Does anybody else see this build problem?

Getting the following when trying to install:

==> Starting build()... Info: creating stash file /home/arp/AUR/openboard/src/OpenBoard-1.5.4/.qmake.stash Project ERROR: Unknown module(s) in QT: webkit webkitwidgets ==> ERROR: A failure occurred in build(). Aborting...

Thanks to loqs at https://bbs.archlinux.org/viewtopic.php?pid=1883212 this should now be solved.
