CCCallFuncN linker error

I have this code snipet:

void MenuScene::startFromTheBegnningCallBack(CCObject* pSender) 
{
this->menu->removeFromParentAndCleanup(false);
this->cloudLayer->removeFromParentAndCleanup(true);
CCFiniteTimeAction * moveMenu = CCMoveTo::actionWithDuration(3, ccp(0, -height));
CCCallFuncN * endFunc = CCCallFuncN::actionWithTarget(this,callfuncN_selector(MenuScene::finalizouMenu));
this->sceneSprites[1].runAction( CCSequence::actions (moveMenu , endFunc, NULL ) ) ;  

};

it throws this error on linker:

if i remove the callfunc the error goes away…

May mistake…

its been a while away from c++ didnt implemented the function properly….
