Installation and Deployment

@NathanJS What exactly are you installing and how?

@kumaran13 Do exactly what the error message suggests

Hi and welcome to devnet,

This rather looks like an online installation.

As the error message suggests, try a different mirror.

@hossein7294 Most important are build-essential and the two mesa. For others you can just execute configure and see what fails - if what fails is needed check what dependencies it requires and install.

After some tests, I have setup the proper qt.conf file and that solved all issues, which were clearly related to paths for plugins and libraries. I think that qt.conf should be systematically used for correct deployment and the document cited by jsulm above is very clear.
Thanks !

I meet the exactly problem, early version no problem, but now only V6.0 above avaialable, but after download and install , always show home/username/Qt/Tools/QtCreator/bin/qtcreator: /lib/aarch64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.32' not found (required b

Well, an app is just one single program. Internally, the "app" is just a folder ending in .app. Inside it you'll find Contents/MacOS and that is where the single executable is located which is launched when opening the app (e.g. double clicking on the folder). If you have additional command line programs those usually are not apps (you'd have to type open mytool instead of ./mytool to run the command on the command line). If these are just called from the main app you can hide them inside the app folder (maybe Contents/Resources or create Contents/bin). Otherwise, Apple also has installer packages (.pkg) which extract several items (instead of just a single app folder) to their appropriate places. There would be an appropriate place for command line tools and the PATH environment variable should also be adapted to make them visible. But, I don't know how to create .pkgs.

If you truly have multiple GUI programs, these should actually be separate apps.

Is it verified already?!

"link expired" window popped

Try to resend the link or contact the Qt Company.

@Pierre-Emmanuel said in Qt 64 bits application:

Maybe or maybe not ?

Not "maybe". Creator (nor Qt itself) has nothing to do with runtime searching for libraries/DLLs for an executable. That is done by the OS/Windows, and that requires them to be found on either PATH or in the same directory as the executable. This would also be the case if you ran your program quite outside of Creator. No OS searches PATH recursively (would be too slow and too dangerous). So something has changed between your Qt5/6 or its environment.

@Robert-Harakaly said in Fetch problem with commercial boot2qt build:

The opensource version builds, thus the problem is in the commercial license configuration.

Then you should probably The Qt Company about this. At least if you don't get an answer here.

OK that was the problem! I think it would be more helpful if selecting archive automatically updated the list of available releases!

I am having similar issues but removing the licence file did not work for me.
Can someone guide me.

After (trying to) run from it Windows File Manager run up Task Manager and see whether the process for the executable is still running. Either it is, in which case for some reason it is not showing any interface, or it is not, in which case either it never ran (and Windows did not give you an error message for some reason) or it ran and exited.

Try running the executable from a Command Prompt. You may get some information there as to whether it runs, when it exits or some helpful message.
