Static member

[ycinar]

I have static member in a class, say class A, in class A i have a static bool attribute xyz. Then I have another class, class B. In class B, I wanna set A::xyz=true;

but compiler gives 2 errors:

error LNK2001: unresolved external symbol "private: static bool...
fatal error LNK1120: 1 unresolved externals

Has anyone got any idea how to get around this?

The static variable is declared as private, so its not available outside class A.
Declare it as public if you want to class B to use it or make Class B a friend class of A´s.


Also dont forget to declare the static variable somewhere in your source code.
I.e.

bool classA::xyz = true;
