I'm back with a GPU.. Qt Creator still not working

[Ronel_qtmaster]

@Mlibu just download an official versions wit kits for your target platform

[Mlibu]

@Ronel_qtmaster So you're saying the dependencies of Qt Creator are not enough? I must also use the other installer to install Qt6 itself?

I usually put that under my home dir. How will Qt Creator detect it?

[Tink]

@Mlibu For normal usage i don't see why you should not just use the package manager. It's there for a reason. With all respect, i do suspect you didnt install correctly. I never had such problems. All i can suggest is removing what you have now and using pacman or pamac to install packages like qt6-base, qtcreator, examples etc.

[Ronel_qtmaster]

@Mlibu install using the official installer.All the packages required will come with it

[Tink]

Well let me add this from the arch wiki as my final comment :)

source: https://wiki.archlinux.org/title/System_maintenance

Use the package manager to install software

Pacman does a much better job than you at keeping track of files. If you install things manually you will, sooner or later, forget what you did, forget where you installed to, install conflicting software, install to the wrong locations, etc.

[Mlibu]

@Tink This was a fresh install of manjaro. All I did was download the online installer and install minimum packages. I install them into /home/user/Qt.

I check next to the following:

Qt Design Studio 4.4.0
Qt 6.6.2 with only Desktop gcc checked under it
Qt Creator 12.0.2

That's it.

When I run qtcreator it does strange things. There isn't a lot I can remove from Manjaro because it needs qt6-tools, qt6-base, etc etc for the OS. And I just delete /home/user/Qt if I'm going to try a reinstall.

[Tink]

@Mlibu you tried the online installer, what can you lose if you try the other approach? Once you done that you can be certain it is not a wrong installation.

[Mlibu]

@Tink Ok but the package manager has never worked for me. I started by doing that.

No examples, no kits, and no documentation on how to set it.

[Ronel_qtmaster]

@Mlibu i feel that you did not selected all the required packages while installing.could you send an image of the packages you have selected while installing?

[Mlibu]

@Tink I'm going to try to install everything but Qt Creator with the online installer then install creator with the package manager. There is nothing else to install in the package manager other than qt creator and optional qt modules..

[Mlibu]

@Mlibu

[Ronel_qtmaster]

@Mlibu okay you have installed desktop kit properly.can you locate it in the installation folder?Because qt would normally have detected it

[Mlibu]

@Ronel_qtmaster I uninstalled and I'm reinstalling everything but qt creator with the installer right now. It will be awhile. After it's done I will try installing qt creator from the package manager again. Note that I am using the Manjaro add/remove programs. I trust that it uses the package manager behind the scenes.

I'm supposed to be executing qt creator and not qt design studio right? Then when I start QT I add the Qt Quick Designer plugin.

Thanks for the help by the way. I'm beginning to lose hope.

[Ronel_qtmaster]

@Mlibu normally it should come with every packages working fine.Have you tried other versions of qt6?

[Mlibu]

@Ronel_qtmaster I have not done that. I will keep that in mind. I would really prefer to use the latest version though that could tell us something.

[Ronel_qtmaster]

@Mlibu ok but latest versions often have some problems till they are fixed and stable

[Mlibu]

@Ronel_qtmaster Ok so I installed everything in the screenshot except for qt creator and then I installed qt creator with the manjaro package manager. Still there are no examples and there is no kit available. When I indicate to start a QtQuick app there is no 'supported platforms' listed and when I select the kit there is none to select.

Should I try Qt 6.5.3 instead of Qt 6.6.2?

One thing I have noticed is that there is a ~/.designer directory. I have not been clearing that, and there is a crash report (maybe old) where a corrupt templates.xml in there can cause problems.

[Mlibu]

@Ronel_qtmaster I tried Qt 6.5.3 and it's still not working.

In fact, the design screen doesn't even draw properly until I build the project. It shows a single empty item when I first start it and none of the controls are responsive at all until I build it. Then it shows a window with a button a field and a label. When I move a rectangle onto the window and go to the properties page to change its color, it works for a couple seconds longer. Then there is a momentary hang where nothing is responding, then Qt Creator is gone. This is happening on every system I try it on and I just want to get coding.

[Mlibu]

@Ronel_qtmaster I just found this error in my journal log right when starting Qt Creator:

Mar 12 15:21:04 cutie plasmashell[6029]: Failed to initialize instances shared memory: "QSharedMemory::handle: doesn't exist"

And I get this when it dies:

@Ronel_qtmaster
So apparently this is an issue in Qt Creator built with Qt 6.6.0+. Bug report

So the only way to create QML is Qt Creator 11 or Qt Design Studio or manual.
