Qt VS Tools Cross-Compile Raspberry Pi won't build

Exioncore

I've been trying to build the default QtWidget project for both the Raspberry Pi and Windows.

Unfortunately I've been experiencing the below issue.

What is the problem here and how do I solve it? I can get it to build for Windows just fine but no luck with the Raspberry PI.
Are there any up-to-date guides on how to set this up properly step-by-step?

Thanks in advance for any help.

The only generated files says the following:

I managed to fix most of the errors but not the "The "HostExec" task failed unexpectedly." and as such I still cannot built the project for the Raspberry Pi.

The other errors I fixed by manually including the linux built qt version like this:

Followed by changing the C++ versions to C++17 like this:

And finally by undefining the following:

I also had to manually open QtDemo.ui in the Qt Designer and save the generated file by going to Form->View C++ Code->Save in the main directory of the projects. Lastly add the file to the actual project as well.

Nobody knows how to sort this out?

I had been working on making an app on windows with the intention of using it on the Raspberry Pi. I was expecting this step to be a walk in the park but it obviously isn't...

Anybody knows of an alternative solution if this can't be sorted out? Or where else can I ask for help about this?

Hello Exioncore,
I can't help you because I haven't gotten to where you are yet! Maybe you can help me, how did you add wt mvc in Qt Vs Tools? I've been trying for days but I can't find solutions. This is the error in visual Studio 2022
