[SOLVED] Inherit from Node but constructor cannot be found?

I'm trying to inherit from Node by implementing a ctor which takes three parameters. But it seems that the ctor is not found during compilation.

Here is my Hand.h:

#ifndef __HAND_H__
#define __HAND_H__

#include "cocos2d.h"

class Hand : public cocos2d::Node
{
public:
    Hand(bool flipHorizontally, bool flipVertically, int numFingers);

    virtual bool init();

private:
    bool _flipHorizontally;
    bool _flipVertically;
    int _numFingers;

    cocos2d::Sprite* _sprite;

private:
    static bool s_fingersInitialized;
    static cocos2d::Sprite* s_fingers[5];
};

#endif // __HAND_H__

And here is the implementation of the ctor in Hand.cpp:

Hand::Hand(bool flipHorizontally, bool flipVertically, int numFingers)
    : _flipHorizontally(flipHorizontally)
    , _flipVertically(flipVertically)
    , _numFingers(numFingers)
{
}

And here is where I'm creating an instance of Hand:

auto hand = new Hand(i == 0, j == 0, 1);

The compilation error message is:

jni/../../../Classes/GameBoardScene.cpp:66: error: undefined reference to 'Hand::Hand(bool, bool, int)'
collect2: error: ld returned 1 exit status
make: *** [obj/local/x86/libcocos2dcpp.so] Error 1

What am I doing wrong? I see some examples using a create(...) function instead of using a ctor. Is there a reason?
