QT creator 11.0.3 issues with default app

Veit

I create a QT quick app in creator.
I select "project which can be used in Qt design studio"
I select Desktop Qt 6.6.0 MinGW 64-bit
then it takes 2 minutes or so, while creator does some background magic, like setting all up, getting some stuff from GIT etc.
After that I press F5 to start. Again it takes 2 minutes and in the "compilation" window I see much compilation happening
And then it crashes
I mean this is an empty demo setup created by the creator. I did not do any changes. Why does it break?

This is a Windows 11 setup, btw. Could it be that there is an issue with file path length? As I did it again now in c:\temp and this looks better. Really? I am confused

Did the previous path contain spaces?

It's mostly a tooling and operating system bug. See https://bugreports.qt.io/browse/QTBUG-117413

Qt Creator is creating a CMake project in such a way that will get result in long paths.

CMake then gives this paths further to ninja / make and then to the compiler. GCC has this bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107974 and even though is an easy fix to add the manifest entry required by Windows ... nobody has fixed it yet.

Visual C++ has the same issue, see https://developercommunity.visualstudio.com/t/compiler-cant-find-source-file-in-path/10221576

The only compiler that's fine is Clang. Ninja also requires a build from latest sources, since https://github.com/ninja-build/ninja/releases doesn't list yet version 1.12.0 which has the one line manifest entry that enables long paths.

I usually say just switch to Linux or macOS, they are way more friendly to developers, and issues like this are non existent.

Or ... just use c:/dev to have short paths 🙂
