Arch Linux User Repository

Since version v1.7.0 the Qt5 backend is no longer actively maintained and supported.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

I needed to apply this patch to have a successful compilation. It looks like the last qt5-webkit moved the QtWebKit/QWebView header to QtWebKitWidgets/QWebView.

Please use and amend this patch at will ;)

@mgisbers Thanks, this dependency is added now. Can you let me know if it still doesn't work?

Seems like it needs sdl as dependency:

[...] /usr/bin/ld: cannot find -lSDL collect2: error: ld returned 1 exit status make[1]: *** [Makefile.Release:1323: build/linux/release/product/OpenBoard] Error 1 [...]

@kbk Thanks, this dependency is added now.

@fsiegert

There is an extra dependency for openboard 1.4.0-1:

libfdk-aac

Thanks

@bderembl Thanks for reporting back. I had qt5-tools installed already so I didn't notice the missing dependency. Fixed now!

awesome. I think there is an extra dependency: qt5-tools works great otherwise thanks

@fsiegert Excellent work! It seems like there are more features now (?) presumably from the resources folder. Thanks for the hard work; it works like a charm!

@hwkiller Ok, thanks for the confirmation. I have added a desktop file now, and also installed some stuff from the resources/ folder into /opt/openboard/ similar to the Ubuntu package provided upstream. To make sure this is picked up I had to move the executable to /opt/openboard/OpenBoard, but I have provided a symlink from /usr/bin/openboard (note new capitalisation consistent with upstream and other dists). It should now find the content of the library. Let me know if you notice any problems.
