Two classes and inline functions
- by klew
I have two classes and both of them uses some of the other class, on example:
// class1.h
class Class1;
#include "class2.h"
class Class1 {
public:
static Class2 *C2;
...
};
// class2.h
class Class2;
#include "class1.h"
class Class2 {
public:
static Class1 *C1;
...
};
And when I define it like in example above, it works (I also have some #ifndef to avoid infinite header recurency). But I also want to add some inline functions to my classes. And I read here that I should put definition of inline function in header file, because it won't work if I'll put them in cpp file and want to call them from other cpp file (when I do it I get undefined reference during linking). But the problem here is with something like this:
// class1.h
...
inline void Class1::Foo() {
C2->Bar();
}
I get error: invalid use of incomplete type ‘struct Class2’.
So how can I do it?
