I have made a class with a static member. The code compiles alright
but i get linking errors saying that they are undefined references.
Maybe i missed something. Here's the code:
//----intrface.h
...
class Interface {
protected:
GraphicsInterface *gi;
DataFile *data;
Config *config;
public:
Interface();
virtual Interface *Update();
virtual void Render();
void SetGraphicsInterface(GraphicsInterface *Gi);
void SetDataFile(DataFile *Data);
void SetConfig(Config *C);
static Interface killer; // ****** here it is
};
//----intrface.cc
...
#include "intrface.h"
...
Interface *InterfaceText::Update() {
if (!key[KEY_ESC]) {
return (this);
}
else {
return (&killer); // ****** link error
}
}
//----ticker.cc
...
#include "interface.h"
...
void Engine(Interface *I) {
Interface *interface = I;
do {
interface = interface -> Update();
interface -> Render();
} while (interface != &Interface::killer); // ****** link error
}
