Question

I am trying to do the folllowing:
class definition h file:

template<int Size>
class Sculptor
{
public:
    Sculptor();

    ~Sculptor(void) ;

    void Sculp(SculptData* sculpData);

    void ToShape(Shape* shape);

    int CalculateMesh();

    unsigned char sculpture[Size][Size][Size];
}

class definition cpp file to shape function (all others are the same):

template<int Size>
void Sculptor<Size>::ToShape(Shape* shape){}

usage:

    Sculptor<16> sclupt;

Shape shape;

SculptData* data = CreateCircle();


sclupt.Sculp(data);
sclupt.CalculateMesh();
sclupt.ToShape(&shape);

and I get the following error

Could you please show me the source of the problem ?

Answer 1

Remember that the implementation of a template class must be visible from the compilation unit that uses it. In particular, you may not place the implementation into a separate .cpp file (as is common practice with non-template classes) but instead should place it in the header file where the template was declared.
