Qt 6.5.3 fails to build examples on Debian 12

[jsulm]

I don't have Qt6 at hand to check but you can simply search for the cmake executable in your Qt installation:

find ~/Qt/6.5.3/gcc_64 -name "*cmake*"

@Axel-Spoerl Since there is no qt-cmake6 on my machine, I simply ran cmake for the example with enabled tracing.
Here is the whole thing: https://drive.google.com/file/d/16HMlyWeO6VLBiAIJLMd5FP_-PoWzRY8k/view?usp=sharing
BTW, is there a way to attach files here?

[alik_co]

@jsulm Of course I have cmake executable, otherwise there wouldn't be any discussion at all. The question was about qt-cmake6, which looks like not available in community edition.

That's why I suggested to search for it in your Qt installation...

[alik_co]

@jsulm I scanned the whole system recursively from '/'. qt-cmake6 is not there. (of course there is tons of *cmake*)

[jsulm]

@alik_co Well, I did not suggest to scan whole system...

I have default installation of Qt 6.5.3 on Debian 12.
Attempt to configure an example ```~/Qt/Examples/Qt-6.5.3/widgets/painting/basicdrawing`` fails:

If ~/Qt/6.5.3/gcc_64/bin/qt-cmake doesn't exist, you have used the installer to install examples, but you haven't installed Qt 6.5.3.
If you launch Qt Creator, does it show a compile kit for 6.5.3?

[alik_co]

@Axel-Spoerl Yes the kit is available. As I mentioned at the beginning, qmake projects work just fine, Qt is definitely installed. qt-cmake does exist, there is no qt-cmake6.
qt-cmake and then make successfully built basicdrawing. But QTCreator still fails to open cmake project, qmake works fine.

[alik_co]

@Axel-Spoerl Complete re-install didn't help. As before, qmake projects work fine, but any cmake fails.

[jsulm]

@alik_co What CMake executable is configured in QtCreator?

[Axel Spoerl]

Well, and since Creator gets the build toolchain from qmake:

• Edit->Preferences->Kits
• select "Qt Versions" tab
• select your Qt version ("Desktop Qt 6.5.3 GCC 64bit")
• what is the "qmake path:"?

[alik_co]

@Axel-Spoerl Found the problem: cmake machinery got broken by custom Default Build Directory (Build & Run -> Default Build Properties). I've been using this configuration with QMake projects with no issues, but CMake got unhappy.

Anyway, to answer your questions:

Qt Versions, -> Qt 6.5.3 GCC 64bit: /home/devwork/Qt/6.5.3/gcc_64/bin/qmake
CMake -> Tools:
   Auto-detected
    CMake 3.27.7 (Qt) (Default)       /home/devwork/Qt/Tools/CMake//bin/cmake
    System CMake at /usr/bin/cmake    /usr/bin/cmake
