Error initializing static member

[prchakal]

Hi

I try use a static object that is a member of a class, but get error:

Undefined symbols for architecture armv6:
  "GameObjects::splashManager", referenced from:
      AppDelegate::applicationDidFinishLaunching()       in AppDelegate.o
ld: symbol(s) not found for architecture armv6
collect2: ld returned 1 exit status

My class header is:

#ifndef GameObjects_H
#define GameObjects_H

#include "SplashManager.h"

class SplashManager;

class GameObjects
{
public:
    virtual ~GameObjects() {}
    static SplashManager *splashManager;
};

#endif 

My class implementation is:

#include "GameObjects.h"

SplashManager *GameObjects::splashManager = 0;

I use it as:

GameObjects::splashManager = new SplashManager();

Can anyone help me to know what im doing wrong?

Try defining the static member right after the class definition.

You don't seem to have specified the class implementation GameObjects.o as one of the input files to ld.

[codekiddy]

use a static factory method to initialize splashManager pointer.

an simple example on how to do that:

class MyClass
{
	static MyClass* getInstance() { return new MyClass; }

public:
	static MyClass* pointer;
};

MyClass* MyClass::pointer = MyClass::getInstance();

Try that patern and it should work just fine.

SplashManager *GameObjects::splashManager = 0;
you don't need to redefine the type of splashmenager, try to use just GameObjects::splashManager = 0; and it should work just fine.

JLBorges, you are correct.

XCode doesnt compile the code. Now its OK, thanks!
