std::make_shared gives error i dont understand

Question

i have map that looks like this:

typedef std::map<PuzzlePartLocation, std::shared_ptr<PuzzleObj>> ComponentsMap;

now i try to set this map with elements via fucntion like this:

void ComponentMadiator::Register(const PuzzlePartLocation puzzlePartLocation,PuzzleObj* puzzleObj)
{
   componentsMap[puzzlePartLocation] = std::make_shared<PuzzleObj>(puzzleObj);
}

i just call it like this :

 PuzzleObj* pPuzzleObjStickLeft = new PuzzleObj()
pComponentMadiator->Register(1,pPuzzleObjStickLeft );

PuzzleObj contains memeber from type IImageComponent *
PuzzleObj inherits from base class

but it give me error like this :

1>c:\program files\microsoft visual studio 11.0\vc\include\memory(873): error C2664: 'PuzzleObj::PuzzleObj(IImageComponent *)' : cannot convert parameter 1 from 'PuzzleObj *' to 'IImageComponent *'

Answer 1

std::make_shared<PuzzleObj> creates a new PuzzleObj for you. What you need is std::shared_ptr<PuzzleObj>(puzzleObj).

More importantly

void ComponentMadiator::Register(const PuzzlePartLocation puzzlePartLocation,PuzzleObj* puzzleObj);

should be declared as:

void ComponentMadiator::Register(const PuzzlePartLocation puzzlePartLocation, std::shared_ptr<PuzzleObj> const& puzzleObj);

because it shares ownership of puzzleObj by storing it in the container and that must be communicated in function's interface.

And call it like so:

std::shared_ptr<PuzzleObj> pPuzzleObjStickLeft(std::make_shared<PuzzleObj>());
pComponentMadiator->Register(1, pPuzzleObjStickLeft);
