Installation and Deployment

Hi, How did you install GStreamer ? Where is it located ?

-multimedia didn't help Ok, I'll stick with manual copy in the build script

Thank you for your feedback, My version of Qt is 6.3.2 In the meantime I have found two errors. The first is that I forgot to specify where my qml files were with the -qmldir option. The second one is from using a Mac M1 and Xcode 14. With this combination the macdeployqt command generates an error when calling install_name_tool See: https://bugreports.qt.io/browse/QTBUG-105056 In short, on Mac Intel and with the -qmldir option macdeployqt works perfectly with QtQuick3D :-) Thanks again, it's nice to be supported here.

@zhangxinyang Did you try a complete rebuild after modifying the pro file (delete build folder, run qmake, build)?

Hi, and welcome! @jhosephfarukh6 said in Qt 5.12.x offline installer download error: Hello; i just tried to download 5.12.x version of Qt but these links (https://www.qt.io/offline-installers) are broken. Could you help me? See https://download.qt.io/archive/qt/5.12/5.12.12/

@kkoehne Thank you so much. That works. Also, another solution is to use an earlier version.

@kkoehne yes, you are right, it was VM with only one CPU, increasing CPUs to 6 fix the problem, thank you

@tristanleboss Hello and welcome. Assuming what you say is correct (I would not know), it's a bit "ugly" but the only way I see to catch inability to load a required DLL which you are already linked against would be to supply a small "wrapper" program which does these checks before invoking your Qt exeutable.

@arad2456 said in Can't get Qt to work on Ubuntu: Ubuntu of windows Which version of Windows Subsystem for Linux (WSL) do you have? The original WSL does not support GUIs. You need WSL 2 with Windows 11 for it to work: https://learn.microsoft.com/en-us/windows/wsl/tutorials/gui-apps Since I practically know nothing in Ubuntu and Linux, I would appreciate it a lot if you could explain it in language I could understand. In this case, I suggest you install Ubuntu in a virtual machine (like VirtualBox or VMWare Player) instead of using WSL.

For future reference here is what I did to work around. First, based on the documentation I thought qt_generate_deploy_qml_script was supposed to do what winqtdeploy did which is scan the exe and dependencies such as Qtcore.dll, etc. Evidently that is not true - at least based on my experience but if I'm wrong I would appreciate knowing how to use it so it does this. So I really don't know what qt_generate_deploy_qml_script does or it's purpose. I fell back to winqtdeploy and ran it in the directory the exe was in. This worked as it generated the folders and files so I could run my exe as a standalone. At some point I plan to try adding winqtdeply as a command to the CMakeLists.txt to pick up any changes needed.

Try running the installer as root.

You can just follow this article: Qt without XCode - how to use Qt Creator for macOS software development without installing XCode

Hi, perhaps you need to upgrade Xcode as well.

@JonB ty JonB, for all the help. qtcreator works, and that is the most important. X11 info was great too :) but i guess, laptop needs a nice format soon ububu@uubunut6ty5y:/$ echo "$PATH" /home/ububu/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/cuda/bin

Hi, I can confirm that the qtmultimedia is giving such parser error during the plugin creation. Just as fabrdidomenico is experiencing with the imx6 target/makespecs I am having exactly the same issue - the only way to complete the build from sources is to disable the multimedia module. Not sure if cmake can be an issue here, I would say that cmake is not responsible at all.

Hi and welcome to devnet, Since you have a licence, you should contact the Qt Company directly.

It's ok now thank you very much for your help! :)

Hi, Ok I uninstalled and reinstalled but with the online installer not from the repository, I got a 8.0 version and everything is working fine. Thanks for your help.
