Qt creator errors highlights



  • Not even sure how to name it. It happened after updates 1 month ago about.
    Now Qt Creator IDE marks things like

    #include <memory>

    as "Error, file not found". Completion works bad too.

    So question is what and where to fix ? I work on the same project more than a year, everything is git versioned, but system update did that (arch-linux).

    Compiler works ok, so it's only IDE problem.



  • Is your project makefile based? Or do you use a pro file?



  • pro/pri files

    Also I started some new project since that (pro/pri) and it has same issue - all system includes not found.

    P.S. Forum forces me to delay in posts as new user for 300s :(

    Yes its for spam protection. :)



  • Unexpected.
    Today my patience went off with KDE-5 (because it starts to swap something when I play MMOs - guess some leaks), I completely wiped it and installed lxqt.
    Now that subj bug with highlights went away. It is just working as expected. Also "ClangCodeModel" plugin works as expected.

    Conclusion - KDE5 is trash.


  • Qt Champions 2019

    @alexzk To be honest: I have no idea how KDE is related to QtCreator issues. It was most probably something else.



  • Possibly, i deleted all configs of kde. Actually I deleted all configs prior 2015 as well I had there (but I kept something named QtProject). Cleared 3-4 gigs.
    But bug happened when I updated from kde4/5 running mix to full kde5 because some tray applets were broken. After this creator went wrong. Now, when kde removed, it's ok again.

    Probably you chose the wrong place to flame at KDE, btw it looks like the update installed a new version of gcc and Qt Creator did not find the includes in the old place. Probably just a change in the environment of the kit would have been enough to fix the problem



  • @VRonin No, Gcc was working ok, everything was ok (even CLion) except qt-creator gui.

    Any way, problem is fixed by removing KDE. Can close thread.
