Installation and Deployment

I also encountered this error and asked the image website administrator. The administrator said that the image file is the same as the official website, but there was an error when installing it into this package and it cannot be downloaded。Upon careful inspection of the mirror website, it was not found that this file exists

@lqsa thanks In addtion when we compile by source with configure.bat for Firebird I used this IBASE_LIBS="-LC:\Qt\Firebird\Firebird_4_0/lib -lfbclient_ms"

@eramne Is it working for you now? I've got a problem linking FFmpeg with static Qt, which I've logged at https://bugreports.qt.io/browse/QTBUG-115052 but if it's working for you, feel free to mark this as Solved

Debian provides all the required documentation. A good starting point is here. As for your issue with linuxdeployqt, depending on the oldest Linux distribution you want to support, you should used a virtual machine with an old enough Linux distribution to allows that.

Like this: set(CMAKE_THREAD_LIBS_INIT "-lpthread") set(CMAKE_HAVE_THREADS_LIBRARY 1) set(CMAKE_USE_WIN32_THREADS_INIT 0) set(CMAKE_USE_PTHREADS_INIT 1) set(THREADS_PREFER_PTHREAD_FLAG ON)

@jsulm Oh, I got it. Many Thanks :D

Yep I just tried again and it worked. Thanks!

@qdoldwolf I don't know, but it would not surprise me if QtWebEngineWidgets does not come with the base packages installed for PySide6. Check to see whether anything with WebEngine in it is in the installed area. You may need to find it explicitly to install via pip, or see https://pypi.org/project/PySide6-Addons/.

Hi and welcome to devnet, Since you are mentioning python, you should follow the PySide6 quick start.

@JonB any solution for this issue MSVC with QT6 complier this issue not in Linux with GCC with QT6

@cristian-adam [6256] QQmlApplicationEngine failed to load component [6256] <Unknown File>: No module named "prometheus_cpp" found I changed my module name and now correctly run thanks!

@Gertio As I said: QtCompany does not provide Qt binaries for Qt5 newer than Qt 5.15.2. If you need a newer Qt5 version you will have to build it by yourself.

Marking this as solved, not because it is, but because I've run into more significant issues building QT since I moved to 6.5.1. Bug report.

@Shawn-Yang The command shouldn't add quotes, like this: open -a ~/Qt/MaintenanceTool.app --args --mirror https://mirror.nju.edu.cn

This mirror contains Qt5 distr: https://qtproject.mirror.liquidtelecom.com What to do when all the mirrors stop keeping the old packages is hard to say.

@MichalF said in Error: Qt license file was not found!: @JonB I know where this folder is located on my computer. I'm asking, maybe the software is looking for it in a different Path than QT_LICENSE_PATH.... It's QT_LICENSE_ FILE not PATH. You need to set it in the same terminal session where you run configure: export QT_LICENSE_PATH=/path/to/your/license/file configure -something -blah And the variable needs to point to the file itself, not the folder where it's located.
