Link errors when extending UBatchLineComponent

I got some link errors when extending UBatchLineComponent this way:

UCLASS(MinimalAPI)
class UPBLineBatchComponent : public ULineBatchComponent
{
    GENERATED_UCLASS_BODY()
public:
    virtual void UpdateBounds();
    virtual FBoxSphereBounds CalcBounds(const FTransform& LocalToWorld) const override;
    void SetTransform(const FTransform &Transform);
    FBoxSphereBounds LocalBounds;
};

It gave me those errors:
