can you build from command line?

Bob K.

I'm new so I had to wait 10 minutes before I could reply and didn't see your message.

For kits I have:

Auto-detected: Qt 6.3.2 MinGW 64-bit (default)
Manual: n/a

You select "Auto-detected: Qt 6.3.2 MinGW 64-bit (default)" and then press apply at the bottom of qt creator.
then build.
click projects->Build in qtcreator
under Build Environment
click details of Use system environment and you can see QTDIR is defined as env variable.

I selected "Auto-detected: Qt 6.3.2 MinGW 64-bit (default)" and then pressed Apply.
And then build, and still have the error.

To be honest, I can't find the options:
projects->Build in qtcreator
Build Environment
Use system environment

I'm not sure where those options are located.

You don't need to set QT_DIR to anything.

All you have to do, is make sure that you Kit has a Qt Version:

alt text

Your CMake project will have in the Initial Configuration -DCMAKE_PREFIX_PATH:PATH=%{Qt:QT_INSTALL_PREFIX}, which will be expanded in current configuration to something like -DCMAKE_PREFIX_PATH:PATH=C:/Qt/6.3.2/mingw_64

Note that there is no lib/cmake/Qt6 or anything like that, just C:/Qt/6.3.2/mingw_64.

That's all that CMake needs in order to find the Qt6 package.

You don't need to change any environment variables, set any QT_DIR CMake variables.

When in doubt just click on the Re-configure with Initial Parameters button, which will clear you CMake configuration and configure the project from scratch.

Thanks cristian-adam. I was able to verify that Qt version. Found the Initial Configuration. Pressed the Re-configure with Initial Parameters.

Now I'm getting the following error:

:-1: error: CMakeFiles/Photography.dir/Photography_autogen/mocs_compilation.cpp.obj:
in function `MainWindow::qt_static_metacall(QObject*, QMetaObject::Call, int, void**)':

Your CMake project is configured with set(CMAKE_AUTOMOC ON), which is not 100% compatible with all Qt software. See more about AUTOMOC in the documentation.

You will have to either turn off AUTOMOC generally, or specifically for "bad" source files with:

set_source_files_properties(bad_source_file PROPERTIES SKIP_AUTOMOC ON)

But if you are skipping AUTOMOC, you will have to use qt_wrap_cpp for the source files that require moc handling.

I've tried the above AUTOMOC settings, and I keep getting the following error:

:-1: error: CMakeFiles/Photography.dir/mainwindow.cpp.obj:mainwindow.cpp:(.rdata$.refptr._ZTV10MainWindow[.refptr._ZTV10MainWindow]+0x0):
undefined reference to `vtable for MainWindow'

Doing a websearch resulted in a post on this forum: https://forum.qt.io/topic/53850/undefined-reference-to-vtable-for-mainwindow

And did you add qt_wrap_cpp() to moc your mainwindow.h as written by @cristian-adam ? Please post your current CMakeLists.txt

Bob K.

I appreciate everyone's suggestions, but at this point I'm going to re-create the project from scratch.

Thanks everyone,
