Installation and Deployment

@JKSH, I'm not sure either! Maybe I'd clicked the wrong button to download the online installer. Weird thing happens, sometimes, when you stay 10 feet away from the screen and fonts are too small.

@jsulm Thank you for quick reply You are right! The built files already exist in those directory ,I cleaned all the built files and then it compiled well. thank your help!

@Mark81 said in How to deploy QSQL plugins: why QPluginLoader told me it loaded the plugin correctly while after a while the application said the plugin were not loaded Because you used absolute path to the plug-in. I'm not sure why the plug-ins are not found, but you can also provide https://doc.qt.io/qt-6/qt-conf.html file where you specify all needed paths.

@jsulm thank you so much it worked with these code: function: void searchPaths(QVariant path) { QStringList files; // add files to this ( paths ) QStringList filter; // mp4 files filter filter << "*.mp4"; // add filter qInfo("-----"); QDirIterator dir(path.toString(), filter, QDir::Files, QDirIterator::Subdirectories); // get all files in directory while (dir.hasNext()) { qInfo() << dir.next(); files << dir.next(); // } } use: searchPaths("enter path here") now i can sleep easy. thanks

@Karthago said in Lubuntu / GUI not starting / qt.qpa.xcb: could not connect to display: until I upgraded Lubuntu through apt-get full-upgrade. What version did you upgrade from/to? My Ubuntu 20.04 uses Xorg display, but later ones will move to Wayland?

@shujja See https://wiki.qt.io/Transition_from_Qt_4.x_to_Qt5 I was never talking about QtCreator. I gave you the link to download Qt 5.7. So, go there download it and install...

For those who have landed on this page when trying to build Pyside2 with QtWebEngineWidgets (not sure for Pyside6 because it seemed to be excluded for now in it), you need to use MaintenanceTool.exe to add Qt5WebEngineWidgets module or reinstall Qt with Qt5WebEngineWidgets checked. After that, PySide2 build will include QtWebEngineWidgets.

@SPlatten said in windeployqt, looks ok, but no files transferred: have got working release dll's and now it all works, thanks for your support. nice to read :)

@jsulm Yes its about the installer.

did you solve this? I have exactly the same issue

Two versions of this lib are in the machine. Therefore, there are conflicts. Removing one solves the problem.

I have this problem for settings: Qt version is not properly installed, please run make install

Thank you jsulm. I tried rsync of target's usr/lib and /usr/include, and set compiler which comes from toolchain. But I didn't success compile. So I gave up to cross compile. It is too difficult for me. I'll try other way to make app with gui ( e.g. Web application style (flask, django ...))

@JonB said in Run on remote device: Cannot create platform OpenGL context, neither GLX nor EGL are enabled I'vw already searched for this error but I found a lot of questions or hints rather than answers. Anyway I tried some of the hints (like the packages above) with no luck. I would like to understand what this error means and how to fix without trying to apply this or that suggestion. I read the docs about deployment but I didn't find a clear list of the requested libraries on a clean environment.

@bgourlay In my case, windows, the .config folder was set in read only mode. Just changed to read-write and the problem was gone.
