    Could it be that there's another header called "system.h" than the one you expect is pulled from somewhere else? can you show your compiler command line (compile output pane)?

        @Imman_Manny There is a system system.h header file. I guess QtCreator thinks you're including that one, but not using. You should avoid using names for header files which are already used for system header files.

          I changed the Header name still error remains .

            @Imman_Manny
            You show you have a Sources > Controllers > system.cpp file. Do you even have a Headers > Controllers > system.h file? Otherwise as @jsulm says you might be best avoiding a system.h named file and possibly a system class.

            While we are on this one of my bug-bears about code written here by beginners. The C++ "standard" is for class names to begin with an uppercase letter, and Qt observes that everywhere. Why people then choose to write classes with lowercase first character is quite beyond me, it goes against convention and makes code harder to read. I would not recommend "system" as a class name, but if you do why in the world don't you make it System?

              @Imman_Manny said in Include Header xxxxx.h is not used directly:

              I changed the Header name still error remains .

              Now that you have changed off it being named system.h. I am not sure what that IDE message is trying to tell you here. It says "fix available", if you click on that or try Alt+Enter or whatever it is that "applies" the suggested fix, what is it that the IDE changes in your code?

                  Now class system is undefined. Presumably it is declared in onesystem.h? Put the #include "onesystem.h" back in, and if the IDE still complains ignore it. Try compiling your code and verify that works.

                      Then ask a new question, presumably in the QML sub-forum. You don't want my help because I have never used QML.

                        false positives for this are so common, it doesn't look like it actually will look past includes that include macros that refer to other symbols in the same subset, this was the case with ncurses, which (unfortunately) loves to declare function-macros (or 'funcros'). My ballpark is that they are expanding the macro, and the since the end result is technically not in the same file, but deeper in, it is missed altogether.

                        Funny how it fails the minute you remove the #include... its almost comical :p

                        I'm truly glad you r/offmychess t finally, but please don't go too far, because you r/beyondvoxels and that implies that u r/donewithlife. Oh well time to git back to the lab, because azure sea here, I have a lot of work to do...
