Quick controls2 basic missing libraries added

Description

Some missing libraries for AppImage were added to QGCPostLinkCommon.pri to load the Quick Controls2 Basic resources

Test Steps

1. Download and enable QGC AppImage as usual into a Linux Distro
2. Run the AppImage
3. Expect to run without issues coming from missing libraries

Should be ok. Any objections @HTRamsey?

[HTRamsey]

@julianoes can you rerun the failed linux builds? We can ignore the android failure

[HTRamsey]

So interestingly this issue started at commit a95dfd1, which changed nothing about the code. However it is where Android Builds started failing. But #11274 doesn't fix the issue, and it doesn't work on my private repo either so it's not related to Qt download caches. It would make sense that this library is required but I don't get why it's randomly needed now and not before. It worked perfectly fine after #11256. My best guess is that this is somehow related to the Qt download source, and something changed there that affected everything else.

@HTRamsey I can squash and rebase both commits (would do anyways later so it goes clean into master), so it can rerun the tests.

My guess is that somewhere someone might be using a raw Qml control instead of the QGC styled ones. These seem to be control style files. That said I don't see how it hurts (other than file size) to include these. Hopefully once we move to cmake all this goes away anyway.

This breaks the Linux build for me. For some reasons I don't have these libraries in my Qt 6.6.1 (or 6.6.2).

Post Link Common
cp: cannot stat '/home/julianoes/Qt/6.6.2/gcc_64/lib/libQt6QuickControls2Basic.so.6': No such file or directory
make: *** [Makefile:2650: staging/QGroundControl] Error 1

This is how I build on Ubuntu 22.04/Linux Mint:

mkdir -p build-desktop && (cd build-desktop/ && ~/Qt/6.6.2/gcc_64/bin/qmake CONFIG+=debug -r ../qgroundcontrol.pro)
(cd build-desktop && make -j30) && build-desktop/staging/QGroundControl

[HTRamsey]

@julianoes do you have any of these?

Was I meant to install something else?

[ddatsko]

Hey. Have you found any ways to solve the broken local build? It fails for me in the exact same way, both on Ubuntu 22.04 with Qt 6.6.1 (I tried installing it both from aqt and the official online installer) and in Ubuntu 20.04 docker built using (slightly extended) this Dockerfile. I just never get the libQt6QuickControls2Basic.so.6 installed

[DonLakeFlyer]

@HTRamsey Any ideas what to do here?

[HTRamsey]

I can look into it more, but at least the issue is just a qmake thing for now. I don't understand why they don't get the QQuickStyles installed

[DonLakeFlyer]

Oh, didn't realize it was qmake only.

Hello guys, any updates on this? I'm getting the same error here. I'm using Ubuntu 22.04.4 LTS. I have installed Qt 6.6.1 via Qt online installer and I'm trying to build using container Building using Containers. I've just cloned the repository so I have the latest commit.

I never get those Qt libs installed:

@julianoes do you have any of these?

Here are the libs that were installed:

$ ls -l /opt/Qt/6.6.1/gcc_64/lib | grep QuickControls2

-rw-r--r--   1 root root   17285576 nov 20 03:00 Qt6QuickControls2Impl.debug

After running the docker run command, it compiles ok, but at the linking stage I get the same error reported by julianoes:

Post Link Common
cp: cannot stat '/opt/Qt/6.6.1/gcc_64/lib/libQt6QuickControls2Basic.so.6': No such file or directory

Use Qt 6.6.3

[AsensioL]

Use Qt 6.6.3

This helped. I changed (locally) ARG QT_VERSION=6.6.1 to ARG QT_VERSION=6.6.3 in deploy/docker/Dockerfile-build-linux
