Mobile and Embedded

Hi and welcome to devnet, I don't have a direct answer to that question but a suggestion: several of Qt Grpc examples avec client and server components. You can test them.

I had the same issue. Adding the following cache variable or setting it in command line with -DQT_DEBUG_FIND_PACKAGE=ON, hinted the issue for me: "QT_DEBUG_FIND_PACKAGE": "TRUE", StateMachine depends on GUI and it depends on WrapOpenGL and that depends on glx library: ... [cmake] -- Could NOT find OpenGL (missing: OPENGL_opengl_LIBRARY OPENGL_glx_LIBRARY OPENGL_INCLUDE_DIR) [cmake] -- Could NOT find OpenGL (missing: OPENGL_opengl_LIBRARY OPENGL_INCLUDE_DIR OpenGL) [cmake] -- Could NOT find WrapOpenGL (missing: WrapOpenGL_FOUND) [cmake] CMake Warning at /home/mohammad/vcpkg/scripts/buildsystems/vcpkg.cmake:904 (_find_package): [cmake] Found package configuration file: [cmake] [cmake] /home/mohammad/Qt/6.10.0/gcc_arm64/lib/cmake/Qt6Gui/Qt6GuiConfig.cmake [cmake] [cmake] but it set Qt6Gui_FOUND to FALSE so package "Qt6Gui" is considered to be [cmake] NOT FOUND. Reason given by package: [cmake] [cmake] Qt6Gui could not be found because dependency WrapOpenGL could not be found. ... [cmake] Found package configuration file: [cmake] [cmake] /home/mohammad/Qt/6.10.0/gcc_arm64/lib/cmake/Qt6StateMachine/Qt6StateMachineConfig.cmake [cmake] [cmake] but it set Qt6StateMachine_FOUND to FALSE so package "Qt6StateMachine" is [cmake] considered to be NOT FOUND. Reason given by package: [cmake] [cmake] Qt6StateMachine could not be found because dependency Qt6Gui could not be [cmake] found. Installing one package fixed my issue: sudo apt-get install libgl1-mesa-dev

Thsi is the result of my test... Kernel 5.10 and Qt 4.8.7 --> sys/class/graphics/fb0/blank works properly!!!!! Kernel 5.10 and Qt 5.15.14 --> sys/class/graphics/fb0/blank FAIL!!!! And more curious with the second case. if I before turn off the screen from terminal and then execute tje Qt app, Qt return a segmentation fault due linuxfb plugin !!!!! What??? in short, QT 5.15 take the control in exclusive mode totally.

@RameshSg said in Boot to QT on STM32MP157x-DK2: i am not getting the options to select Embedded Linux Don't you have to load a QBSP file file first as described there? To my knowledge Boot2Qt is a commercial offer, you should ask QtCompany directly for support.

Is there a way to remove these flags by cmake without needing to interact with xcode?

Thanks, yes I may go the subclass route. It's not a behaviour that I've seen before in Qt. It seems odd that Android should make the control loose focus. When I say last character, it even does it when there are characters left. Anyway, thanks for you reply.

Thank you, let me try, but I did all of them already :D Does QT have an exampe of app extension?

It looks like something that should be reported on https://bugreports.qt.io . Maybe related to the internal clipping TextField does if the issue isn't reproduced by TextInput.

It is possible that this problem was caused by a wrong NDK version? After I reinstalled the NDK with Anroid Studio, the problems are solved.

In my case, for a stable WebEngine application using the Lima driver, Linux kernel version 6.1 or later and Mesa version 23.3.4 or later are required. After upgrading the Linux kernel from 5.4.47 to 6.1, the issue was resolved.

I have the same problem. Buildroot 2025.08.1 and Qt 6.8.2. Did you manage to find a solution?

Did you solve this error? I am getting the same error when compiling for QT 6.8.5 app for QNX

II wanted to post the source code for a test app here, so one could compile it and see what it looks like. But all my attempts end with a message that the post was recognized as spam, and I can't attach the source code here. So I posted all source code at the StackOverflow https://stackoverflow.com/questions/79801790/qt-5-15-6-10-qml-with-webview-in-the-widget-app-shows-empty-field-instead-of

I must reply to my own question. In the mean time I found the problem. I defined the parameter: -DCMAKE_APPLE_ARCH_SYSROOTS=iphonesimulator This is wrong because it must be a path to the SDK root. After removing this parameter configure succeeded and it compiled as expected. A.T.

I had this situation, it turns out you have to link explicitly with Qt6::QDarwinBluetoothPermissionPlugin

It fixed by deleting a cmdline-tools directory from SDK directory
