            if inside .cpp
            like
            include A.h
            include B.h
            then its pretty normal.
            and its not that.

            Try a clean file.
            and try use the class i dont know and see if same thing happens.

              @saber Can you show coreedit.h and corepad.h? But please not as screen-shot!
              Is coreedit in a namespace?

                  @saber Since you're only using a pointer to coreedit it would be enough to have a forward declaration. So, instead of including coreedit.h (remove it) you can do:

                  class coreeedit;
                  class corepad: ...
                  

                  And include coreedit.h in corepad.cpp.

                    i first commented the third.cpp from the coreedite.h then it builds fine.
                    and reverse the way it dose not build .

                    so the circular reference is happing through another cpp file.
                    here it is #include "utilities/utilities.h" ,see it is included in both header file.

                    what can i do?

                      @saber Get rid of circular dependency. How? Read my post above about forward declarations. And think about your design: does a utility class really need to know about coreedit?

                        i can confirm that the cause is circular dependency.
                        i restructured my cpp files and function .sperated the function that used by every cpp file .
                        now it fixed.
                        sorry i did not understand the forward declaration.but i will try to understand .

                          @saber Forward declaration is just a declaration of a class without definition (without class body):

                          class coreeedit; // This is forward declaration
                          class corepad: ...
                          

                          Farward declaration in this case tells the compiler that coreedit is a class, this is already enough information for compiler to declare pointers to coreedit. But in cpp you need to include the header file with coreedit definition, so compiler knows more about it to be able to access its variables and methods.

                            i saw those in many cpp files.i understand now those.
                            thanks
