Brewtarget 4.0.7 Qt6 issue on Ubuntu (libQt6Multimedia.so.6 missing)
Closed this issue · 20 comments
4.0.7 seems to have moved from Qt5 to Qt6.
- On my Ubuntu system I first install Qt6 with
sudo apt install qt6-base-dev - Install 4.0.7 with
sudo dpkg --install brewtarget-4.0.7_24-1_amd64.deb - Run 4.0.7
/usr/bin/brewtarget - Error:
/usr/bin/brewtarget: error while loading shared libraries: libQt6Multimedia.so.6: cannot open shared object file: No such file or directory
It seems that package qt6-base-dev does not contain the Multimedia component whereas qt5-base-dev did. I can't find a package containing it or another way to install it.
Also, I suspect the same issue with occur with the SVG and LinguistTools components, which also appear to be absent from the Ubuntu Qt6 base package.
Hello,
Yes, you're right, we did indeed move to Qt6 (see #841).
Qt has several different components you need to install before you can build from source. The simplest way to set everything up is to run the following from the top level directory:
./bt setup all
This will install all the packages you need.
If you'd rather install everything manually, have a look at lines 400-712 of https://github.com/Brewtarget/brewtarget/blob/develop/scripts/buildTool.py, which is the main script that gets invoked by the bt tool. It's all Python so should be relatively straightforward to follow, and I've tried to comment the reasons for all the different things it does. There will be one or two bits you can skip if you're just building for local install (ie you don't also need to build the distributable packages), but it won't hurt to have them either.
Hope this helps. Give us a shout if you hit any other problems.
TBH I wasn't even trying to build from source on this occasion, just installing from the latest deb package.
Anyway, I did run ./bt setup all and following that I was able to both install the deb and build locally on ubuntu. Thanks.
Ah, if you were installing the deb package, it could well be that we're missing some dependencies. I'll have a look and include them in the next PR. Likely involves adding some lines to https://github.com/Brewtarget/brewtarget/blob/develop/packaging/linux/control.in and https://github.com/Brewtarget/brewtarget/blob/develop/packaging/linux/rpm.spec.in. Re-opening this ticket so I don't forget!
This is what happens trying to install the latest deb on a clean ubuntu system that was never used to build from source:

Try sudo apt -f install ./brewtarget-4.0.7_24-1_amd64.deb. I think that will automatically install the dependencies (whereas dpkg won't.)
We should now have all the correct dependencies listed in the 4.0.8 release. If you use sudo apt -f install or gdebi it should be able to read these dependencies from the package and install any missing ones. Please don't hesitate to reopen this ticket if it doesn't work!
4.0.8 installed with sudo apt -f install but the icons appear to be missing in the app...
Ooh, how odd. Although they are separate files in the source code, those icons get incorporated into the executable as Qt "resources", so it's a bit surprising they are missing. (Or at least it's more surprising than if we had some issue with building the package.) Are there any errors or warnings in the log file?
I don't see anything in the log...

This installation was on Linux on a Chromebook. I had previous brewtarget releases installed on this system and they always worked perfectly, including showing the icons.
I have just now tried installing 4.0.8 on a baremetal linux system and the icons are showing so that's a bit odd. Perhaps it's somehow related to linux on the Chromebook.
There are a couple of things I can try. I'm not super hopeful that they will fix things, but it can't hurt to try them:
- We don't currently call
Q_INIT_RESOURCEat program start-up, so I'll add a call to that - You're the second person that has a warning about
Localization::loadTranslations()failing, so I'll see if we can make that more robust
Hi Anthony, When you get a chance, could you let me know if you're still seeing the missing icons problem in the 4.0.10 release?
Hi Matt - the icons are still missing in my Ubuntu on Chromebook in 4.0.10. There is still no issue on my Ubuntu baremetal system.
This extra line appears in the log on the Chromebook versus the standard Ubuntu system.

BTW both systems have Ubuntu 24.04.1 LTS
Hi Anthony, I'm wondering if the issue you're seeing on Ubuntu/Chromebook is related to the missing icons being .svg files, given that the logo, which does show, is one of the few things that is .png rather than .svg. I'll see if I can find out more.
I made a couple of changes to the bt script in the 4.0.11 release to ensure it installs the Qt SVG libraries. If that doesn't fix things, it may be that we are missing a dependency in https://github.com/Brewtarget/brewtarget/blob/develop/packaging/linux/control.in.
Unfortunately the issue persists in 4.0.11 on Ubuntu on Chromebook.
Thanks for letting me know. I'll keep digging.
I will try the fix in https://stackoverflow.com/questions/76047551/icons-shown-in-qt5-not-showing-in-qt6 for the 4.0.12 release.
That looks promising.
I could test it by installing libqt6svg6 on the Chromebook but I think it'd be better to wait for 4.0.12. I never installed a build environment on the Chromebook so it's a nice clean test bed.
Hopefully this is fixed in 4.0.12. If not, please don't hesitate to reopen this issue!
Yes, fixed:
