I'm trying to create a set function that will take in a shared pointer and set it equal to another shared pointer.
This is the shared pointer and the set function that i have declared on my header file
class Shape
{
public:
Shape();
Gdiplus::Point start;
Gdiplus::Point end;
std::shared_ptr<Gdiplus::Pen> m_pen;
virtual LRESULT Draw(Gdiplus::Graphics * m_GraphicsImage) = 0;
void setPen(std::shared_ptr<Gdiplus::Pen> pen2);
void setStart(int xPos, int yPos);
void setEnd(int xCor, int yCor);
};
but when i try to implement it in my cpp i get an error saying that my "declaration is incompatible with void setPen declared on .h". it also says m_pen is unedintified on my cpp file.
#include<memory>
#include "stdafx.h"
#include "resource.h"
#include "ShapeMaker.h"
void Shape::setPen(std::shared_ptr<Gdiplus::Pen> pen2)
{
m_pen = pen2;
}
void Shape::setStart(int xPos, int yPos)
{
start.X = xPos;
start.Y = yPos;
}
void Shape::setEnd(int xCor, int yCor)
{
end.X= xCor;
end.Y = yCor;
}
That's literally all i have. the stdax.h includes
#include <atlwin.h>
#include <atlframe.h>
#include <atlctrls.h>
#include <atldlgs.h>
#include <atlctrlw.h>
#include <atlscrl.h>
#include <GdiPlus.h>
Errors that I get:
shapemaker.h(11): error C2039: 'shared_ptr' : is not a member of 'std'
shapemaker.h(11): error C2143: syntax error : missing ';' before '<'
shapemaker.h(11): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
shapemaker.h(11): error C2238: unexpected token(s) preceding ';'
.h(16): error C2039: 'shared_ptr' : is not a member of 'std'
shapemaker.h(16): error C2061: syntax error : identifier 'shared_ptr'
shapemaker.cpp(9): error C2511: 'void Shape::setPen(std::tr1::shared_ptr<_Ty>)' : overloaded member function not found in 'Shape'
I'm posting my answer from the comments for any visitors.
The problem is at the beginning of the cpp file.
#include<memory>
#include "stdafx.h"
#include "resource.h"
#include "ShapeMaker.h"
MSVC++ demands that the precompiled header "stdafx.h"
precede any other code in your source files.
The #include<memory>
must be removed, and instead placed in "ShapeMaker.h"
where it is first needed.
