    Hello,

    As of this morning I'm having a problem bulding a project I've been working on for some time:

    No rule to make target '/usr/lib/libQt6Widgets.so.6.3.1', needed by 'MyProject'.  Stop.
    

    Everything was OK until now, then there was an OS update (manjaro KDE), after which the error appeared. Any clues?

    TIA

      @ForeverNoob Do a clean rebuild:

      • Delete and recreate build folder
      • Run CMake
      • Build
        Probably Qt was updated to newer version.

        That worked perfectly. Thanks a lot.
