shared_from_this problem?

[lucky6969b]

I've got a class which derives from an abstract class and enable_shared_from_this<>
however, I have fully implemented the abstract class, but I can't use shared_from_this()
to get a pointer of itself.

class AABB : public AStarNode2, public enable_shared_from_this<AABB>
{
public:
	// Initialize to an infinitely small AABB.
	AABB();

	AABB(LPDIRECT3DDEVICE9 pDevice, int x, int z, const D3DXVECTOR3& min, const D3DXVECTOR3& max);

	AABB(LPDIRECT3DDEVICE9 pDevice, CMesh* pMesh);

	DWORD GetID() const {
		return m_id;
	}

	DWORD Get_ID() {
		return lastId++;
	}
	 
	D3DXVECTOR3 GetPos() const { return m_vPos; }
	D3DXQUATERNION GetRot() const { return m_rot; }
	D3DXVECTOR3 GetSize() const { return m_size; }
	float GetRadius() const { return m_radius; }


	void SetPos(D3DXVECTOR3 pos) { m_vPos = pos; }
	void SetRot(D3DXQUATERNION rot) { m_rot = rot; }
	void SetSize(D3DXVECTOR3 size) { m_size = size; }
	void SetRadius(float radius) { m_radius = radius; }



	D3DXVECTOR3 GetCenter() {
		return center();
	}

	void GetBox(D3DXVECTOR3* vMin, D3DXVECTOR3* vMax);	 

	void Render();
	 

	bool Intersect(AABB &b);
	bool Intersect(Rays &ray);
	bool Intersect(D3DXVECTOR3 &point);

	D3DXVECTOR3 GetContactPoint(Rays &ray);

	vector<D3DXVECTOR3> GetCorners();


public:
	void setNeighbours(std::vector<boost::shared_ptr<AABB>> neighbours);
	float getCostEstimate(boost::shared_ptr<AStarNode2> dest, const boost::shared_ptr<PathContext2> pc);
	// Get generic transitions without getting into the reserved particulars
	std::vector<boost::shared_ptr<AStarTransition2>> getTransitions(); 

	int GetX() const { return m_x; }
	int GetZ() const { return m_z; }
	
private:


	D3DXVECTOR3 center()
	{
		return 0.5f*(minPt + maxPt);
	}


	static DWORD		lastId;
	DWORD				m_id;
	
	LPDIRECT3DDEVICE9	m_pDevice;

	D3DXVECTOR3			minPt;
	D3DXVECTOR3			maxPt;
	int                 m_x;
	int                 m_z;
	D3DXVECTOR3			m_size;
	float				m_radius;
	D3DXVECTOR3			mCenter;	

	D3DXVECTOR3         m_vPos;
	D3DXQUATERNION      m_rot;	 	 
	bool                m_bRenderable;
	 

	CComPtr<ID3DXMesh> mBoundingBoxMesh;

public:
	std::vector<boost::shared_ptr<AABB>> neighbours;
	std::vector<boost::shared_ptr<AStarTransition2>> transitions; 
};

void AABB::setNeighbours(std::vector<boost::shared_ptr<AABB>> neighbours) {
	this->neighbours = neighbours;

	for (std::vector<boost::shared_ptr<AABB>>::iterator it = neighbours.begin(); it != neighbours.end(); it++) {
		boost::shared_ptr<AABB> neighbour = (*it);
		boost::shared_ptr<AABB> self = shared_from_this(); <<<<<<<< can't do this
		boost::shared_ptr<GridTransition2> tran(new GridTransition2(self, neighbour));
		boost::shared_ptr<GridTransition2> trans(tran);
		this->transitions.push_back(trans);
	}
}

Error	1	error C2440: 'initializing' : cannot convert from 'std::shared_ptr<_Ty>' to 'boost::shared_ptr<AABB>'	e:\jacky\documents\visual studio 2013\projects\perfectsim\perfectsim\perfectsim\aabb.cpp	318	1	Perfectsim

I don't understand why. Could anyone please give me a clue?
Thanks

cannot convert from 'std::shared_ptr<_Ty>' to 'boost::shared_ptr<AABB>'

Either use std::shared_ptr, or boost::enable_shared_from_this.
