  Hi and welcome to devnet, What do you have in mind when saying deployment ? Call the XXXdeployqt helper application for your OS ?

  Hi, I'm not sure if it fits for your system, but did you come across https://wiki.qt.io/Raspberry_Pi_Beginners_Guide and https://forum.qt.io/topic/68381/cross-compile-qt-windows-to-raspberry-3 ? BR Sebastian

  @JKSH, thanks! That is a good idea and I've tired (oh, what a funny typo, so true ;-)) tried that in many variations. After all, I did the (unnessecarily dreaded) reinstall. But that was not the end of the story... After renaming the whole Qt folder and reinstalling from scratch (at first: only a few parts of 5.13.1 MinGW64 checked) I ended up with 5.13.1 AND 5.12.4(!) in the (new!) folder. I don't have a clue where MaintenanceTool has its bookkeeping - it shouldn't have thought about 5.12.4 at all, the whole Qt folder was renamed! But that was actually a breakthrough, though, because now I could uncheck and remove this version (5.12.4) without errors, so that by now MaintenanceTool seems to actually believe, that it's gone. So the central question remains: where does MaintenanceTool store information about what's installed on a machine? This is puzzling. Just in case anybody might be able to shed some light on this, I'll leave this tread as "Unsolved" for some more time.

  @hobbyProgrammer Hello I am the author of the QtDeployer utility. This utility was written specifically to solve the problems you are trying to solve. However, at the moment, the utility can create distributions only from the already created qt components. this means that you must: Prepare the qt framework assembly using a cross-platform compiler. Build your project using a cross-platform compiler with the qt framework created in the 1st step. Using cqtdeployer to collect all dependencies into one distribution. For the third step, only the cqtdeployer utility is suitable, because it is the only one that has its own ELF PE and QML parsers. In the process of developing my programs, I use a Linux-based server to create applications for Windows and Linux. You are not the first to try this way, so I’m thinking of writing an article on how to deploy applications on the same host for different platforms.

  @Sekhar Please take a look at https://doc.qt.io/qt-5/linux-deployment.html But your issue could be different: did you cross compile Qt with EGLFS support?

  Became much to complicated, so I just put nfsserver on pi and mount / as sysroot. Way too many places to set solib-search-path" or "set sysroot"? just mounting the entire sd as an nfs mount to sysroot was a lot easier. On the display, the click check box and enter the DISPLAY did not work for me, I had to actually make an env value in Build Environment and place it there. DISPLAY localhost:10.0 there... It did not work for me in the run in terminal click to forward to this display... don't know if I am doing something wrong there or if this is bug.. but the correct place for me was in the Build Environment ...

  Hi and welcome to devnet, Your for line is wrong. It should be: for (CVLIB, CVLIBS) { # Your code here } qmake's syntax is not the same as C++. You have to have the opening bracket on the same line as the test/loop/etc..

  The problem is simple: you are trying to create the database in the same folder as your application. That won't work on mobile. It also won't work on desktop if you install the application in the system because usually they will be rightfully put in read-only places. You should use QStandardPaths to get a suitable folder for your application to write into.

  @BK_Broiler If you don't need the tools then don't build them. Otherwise I guess you need to satisfy the requirements like CLang (QtCreator uses it for example).

  Looks like you're right. sudo apt list | grep qt5 revealed the qt5 version for the OS is 5.9.5, which would give QtQuick 2.9. I suspect there isn't a way to update the OS version without switching to Kubuntu. Thanks for your help!

  Thanks for the input. On WIndows, when you run the Maintenance Tool you check off which compiler you want to use. The Maintenance Tool downloads that compiler. At the point this error happens I have seen the Maintenance Tool download the correct compiler to the Qt directory.

I searched manually: deleted folder config.tests cleared files config.summary, config.opt, config.log, config.cache. Then I qmake include and lib from MYSQLSERVER8.0 folder... And that works... Now I'm connected with my mysql database...

  @mkre said in Android build issues with OpenSSL on 5.0/5.1: @sierdzio Is there a guide for either of these two solutions? Running into this issue now for an APK I'm trying to build for an Android 5.0/5.1 device that uses QNetworkRequest to download files from the internet. Option 2 (workaround) is described in the linkg @kviktor posted, just above your comment. As for compiling Qt statically, look in Qt docs and output of ./configure --help. Please remember license (LGPL, GPL) limitations when compiling statically.

  Well, since you want to use your desktop environnement on your target. Just don't pass the embedded option when configuring Qt. You'll have a standard desktop Qt but built for ARM.

  You can add this to the Controller() function in your installer script: function Controller() { installer.setMessageBoxAutomaticAnswer("installationErrorWithRetry", QMessageBox.Ignore); installer.setMessageBoxAutomaticAnswer("installationError", QMessageBox.Ignore); } This will automatically click "ignore" on the message box that comes up when the Visual C++ redistributable is already installed. See the docs for more info.

  @aha_1980 I apologize. Please understand: I didn't try what you suggested because it wasn't what I was looking for. I appreciated a lot your answer because it put me on the right way. I found the file to configure Qt5: layers/meta-st/meta-st-openstlinux/recipes-samples/images/st-example-image-qt.bb inside it defines what to build, example: # QT part Essentials IMAGE_QT_MANDATORY_PART = " \ qtbase \ liberation-fonts \ qtbase-plugins \ qtbase-tools \ qtdeclarative \ qtdeclarative-qmlplugins\ qtdeclarative-tools \ qtgraphicaleffects-qmlplugins \ qtmultimedia \ qtmultimedia-plugins \ qtmultimedia-qmlplugins \ qtscript \ openstlinux-qt-eglfs \ " # QT part add-ons IMAGE_QT_OPTIONAL_PART = " \ qtserialport \ "
