正在尝试引用已删除的函数(VS2013）

我正在尝试用SDL编写一个跳棋游戏。当我编译代码时，我会得到以下错误：

std:：basic_ifstream>：：basic_iffstream(conststd:：basic_ifstream>&)'：试图引用已删除的函数

根据我在网上找到的信息，这意味着编译出于某种原因删除了我的构造函数，现在它再也找不到了。(如果你问我，组织不好)为什么会这样？

Board.h:

#include <fstream>
class Board
{
public:
SDL_Surface * boardSurface;
int boardArray[8][8];
private:
std::ifstream boardFile;
SDL_Surface * blackPiece;
SDL_Surface * whitePiece;
SDL_Surface * darkSquare;
SDL_Surface * lightSquare;
public:
Board(char filename[], SDL_PixelFormat * format);
private:
void loadFile(char filename[]);
void makeSurface();
void debugPrint();
void debugBlit();
};

Board.cpp:

#include <SDL.h>
#include <fstream>
#include <iostream>
#include <stdlib.h>
#include "board.h"
#include "loaders.h"
Board::Board(char filename[], SDL_PixelFormat * format)
{
//inits images
loaders imageLoader;
blackPiece = imageLoader.load_image("images/blackPiece.png", format);
whitePiece = imageLoader.load_image("images/whitePiece.png", format);
darkSquare = imageLoader.load_image("images/darkSquare.png", format);
lightSquare = imageLoader.load_image("images/lightSquare.png", format);
boardSurface = SDL_CreateRGBSurface(0, 780, 480, 8, 0, 0, 0, 0);
loadFile(filename);
debugPrint();
debugBlit();
}
void Board::loadFile(char filename[])
{
boardFile.open(filename);
char currentLine[9] = {};
for (int line = 0; line <= 7; line++)
{
boardFile.getline(currentLine, 9);
for (int square = 0; square <= 7; square++)
{
int currentSquare = (int)currentLine[square] - '0'; 
boardArray[line][square] = currentSquare;
}
}
}
void Board::makeSurface()
{
}
void Board::debugPrint()
{
for (int line = 0; line <= 7; line++)
{
for (int square = 0; square <= 7; square++)
{
std::cout << boardArray[line][square];
}
std::cout << std::endl;
}
}
void Board::debugBlit()
{
for (int y = 0; y <= 4; y++)
{
if (SDL_BlitSurface(blackPiece, NULL, boardSurface, NULL) != 0)
{
std::cout << SDL_GetError();
}
}
}
