cant open file .exe 1104 [duplicate]

问题

I'm using sfml 2.0. I know I can ask on there forum but I don't think it has anything to do with linking a library wrong because I compiled an example project fine and it's pretty much the exact same thin I'm just trying to incorporate an external class. I get this when I try to compile

1> LINK : fatal error LNK1104: cannot open file 'C:\Users\brr\documents\visual studio 2012\Projects\sfmlgame\Release\sfmlgame.exe'

My code is as follows:

main.cpp:

#include "functions.h"
int main()
{
    functions func;
    std::cout << "Testing 123, testing 123!";
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);
    bool running = true;
    while (running)
    {
        func.window.clear();
        func.window.draw(shape);
        func.window.display();
    }
    return 0;
}

functions.h:

#pragma once
#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>
#include<SFML\Network.hpp>
#include <SFML/Window.hpp>
#include <iostream>

class functions
{
public:
    functions(void);
    ~functions(void);
    void Events();
    void Window();
    sf::RenderWindow window;
    sf::Event event;
};

functions.cpp:

#include "functions.h"
functions::functions(void)
{
}

functions::~functions(void)
{
}

void functions::Window(){
    window.setSize(sf::Vector2u(800,600));
    window.setTitle("Test");
}

void functions::Events(){
    while (window.pollEvent(event))
    {
        if (event.type == sf::Event::Closed)
            window.close();
    }
}

回答1:

There are two possibilities.

1. You don't have access to the C:\Users\brr\documents\visual studio 2012\Projects\sfmlgame\Release directory. You can check by attempting to create a new file in this location.

2.The process is already in use. Run task manager(start->run->taskmgr), and check if sfmlgame.exe is running. If yes, kill the process.

回答2:

go to task manager
go to Processes tab
look for the desired exe file
click on End Processes
build for project again

回答3:

One usually gets this error when they have the program (sfmlgame.exe) already open/running, so visual studio can't replace it with the newly compiled one. Close the program if you are already running it, then try again.
