Installation and Deployment

I mean the mirror used by the installer to get its data and packages. See here. No, there should not be that big a difference between these two minor release. A module can be a TP but in that case, it's clearly noted as such

Assuming you run configure in qt source directory, you can specify QMAKEFEATURES like this: QMAKEFEATURES=$PWD/qtbase/mkspecs/features \ ./configure

@Ronel_qtmaster The OP asked for Qt 5.15.15, you show version up to 5.15.2. Be aware too that recently there was a long discussions where apparently versions like 5.15.x seemed to be available for download to some people but not others, perhaps depending on their platform. I don't know whether anyone figured out definitively what was going on.

You need to run the installer from the command line and switch to another mirror. https://doc.qt.io/qt-6/get-and-install-qt-cli.html

check the archive checkbox.

@SGaist I couldn't find anything that was wrong or why it was not working so decided to spend my time/energy in getting a clean install of Ubuntu 24.04 up and running and then built Qt6.7.1 with all the dependancies. I've just built QT Creator succesfully against my 671 build and so got what I wanted in the end. Thanks for your comments and pointers, time to go play with making Creator widget plug ins now :-)

Please properly format your code so others can read it. When you use a class/function from a library, you also have to link against it. You are using the QSerialPortInfo class so you also must link against the library which contains it as written in the documentation.

Try another mirror.

I would rather expect to see qt_import_plugins(XXXX INCLUDE_BY_TYPE multimedia).

Thanks @Christian-Ehrlicher for you guide, I read about linking the components and now the initial error about Undefined symbols for architecture x86_64 was fixed. I add the links to the CMakeLists.txt as follows: find_package(Qt6 REQUIRED COMPONENTS Sql) target_link_libraries(EAPSolution PRIVATE Qt${QT_VERSION_MAJOR}::Widgets PRIVATE Qt${QT_VERSION_MAJOR}::Sql)

use gcc10 & g++10 test

@name101 I'm having the same problem now, how did you solve it? and what did you reinstall ?

Please set QT_DEBUG_PLUGINS env variable before starting your app and then check the output: it should say exactly what is wrong. See https://doc.qt.io/qt-6/debug.html

Thank you @Pl45m4 That's not my case, but it's good to know :-)

@lorn-potter This post was done on Nov 2019: waht about the same question for now? AFAIK, Qt3D no more depends on OpenGL: instead it renders via RHI backend. So, is it possible now to make Qt3D work on WebAssembly?

@SGaist In my case the source folder is the one generated by just compiling. So far, it only contains a single executable. Symbolic links would have to be adapted anyways to not point outside the AppImage we are creating.
