@JRaith The easiest solution you could go with, is to create a new widgets project, and just get the code you need from this project to replicate it.

And if this is not your original code, you missed getting a ui file, most likely called mainwindow.ui.

@JRaith
My previous reply states what the problem is. You either have not done a build which would generate the ui_....h file from the .ui file, or from what I can see you don't even seem to have any .ui file so I have no idea where you got the code from or expect it to work if that is the case.

@JonB I'm having a similar problem with CMake using Qt6. I can't get the program to run and i can't get it past this point, since the ui_mainwindow.h file cannot be found.

Please assist if possible. I have gone through the existing threads on this issue and none of the previous solutions or suggestions have worked.

Hello and welcome.

Please state how your situation differs from the link you reference, where the reply was:

@jsulm said in Qt CMake Semantic Issue:

@qtcat Did you build your app?
ui_mainwindow.h is a file which is generated during build. If it is not yet there (because you did not yet build), QtCreator will show this errors/warnings because it does not know what Ui::MainWindow, which comes from that generated file, is.
