[Nine_Masquerade_]

When compiling i get this error log:


**** Build of configuration Default for project ITAWAS ****

here is how i declared shop in main.c:

Code: Select all

	Shop *shop;
	shop = new Shop;

Here is Shop.h:

Code: Select all

#pragma once
#include <string>
#include <vector>

//#include "Player.h"


class Shop
&#123;
public&#58;
	Image *BG;
	Image *img;

	int WIDTH;
	int Y;
	int X0;

	int X1;

	int X2;

	int X3;

	int X4;

	bool firstPass;

	int xCoordinates&#91;5&#93;;
	bool inventory&#91;5&#93;&#91;10&#93;;
	int costs&#91;5&#93;&#91;10&#93;;
	int arrowCoords&#91;5&#93;&#91;10&#93;;

	int left;

	int right;

	int still;

	int dir;

	int current;

	int dis;

	int choice;
	int selectedUpgrade;
	int numUp;

	std&#58;&#58;string side;


	//0 = image, 1 = stats

	std&#58;&#58;vector<Image*> shotgun;

	std&#58;&#58;vector<Image*> minigun;

	std&#58;&#58;vector<Image*> uzi;

	std&#58;&#58;vector<Image*> flamethrower;

	std&#58;&#58;vector<Image*> dragown;

	std&#58;&#58;vector<Image*> money;
	Image *pointer;
	Image *incr;


	std&#58;&#58;vector<std&#58;&#58;vector<Image*>*> weapon;


	std&#58;&#58;vector<Image*> upgrades;

	std&#58;&#58;vector<Image*> display;

	//Arrows 0,1 = Left 2,3 = Right

	std&#58;&#58;vector<Image*> arrow;


	std&#58;&#58;vector<Image*> fist;

	std&#58;&#58;vector<Image*> heart;

	Shop&#40;&#41;;
//
	virtual void draw&#40;&#41;;
//
	virtual bool act&#40;bool L, bool R, bool U, bool D, bool E, bool esc&#41;;
&#125;;

Here is Shop.cpp:

Code: Select all

#include "Shop.h"

Shop::Shop()
{
code
}

void Shop::draw()
{
code
}

bool Shop::act(bool L, bool R, bool U, bool D, bool E, bool esc)
{
code
} 

Thanks for any help.

[slasher2661996]

Shop shop = new Shop();

[hlide]

Shop shop = new Shop();

I'm sorry but :

Code: Select all

Shop *shop = new Shop;

is perfectly valid and should not be the issue. And you're plainly wrong without "*".

@OP: It seems Shop.o is missing in your OBJS flag (Makefile), so it cannot resolve the address of your VMT which is normally defined in Shop.o.

really? i was reading the error wrong, sorry :/
