Annoying error when I try to build my game, help please

[louie]

So I get this weird error:

||=== Build: Debug in test (compiler: GNU GCC Compiler) ===|
C:\Games\SFML Games\Test\main.cpp||In function 'int main()':|

||=== Build failed: 8 error(s), 0 warning(s) (0 minute(s), 1 second(s)) ===|
 

This is my code:
main.cpp:

#include <SFML/Graphics.hpp>
#include "states.hpp"
#include "menus.hpp"
#include "gameloop.hpp"

#define WINDOW_WIDTH 640
#define WINDOW_HEIGHT 480

int main()
{
    sf::RenderWindow window(sf::VideoMode(WINDOW_WIDTH, WINDOW_HEIGHT), "Game");

    INIT_MENUS();

    MAIN_GAME_LOOP(window);

    return EXIT_SUCCESS;
}
 

gameloop.cpp(where the MAIN_GAME_LOOP and INIT_MENUS functions come from)

#include "gameloop.hpp"

void INIT_MENUS()
{
    Game::MenuButton start_button1("Start", 25, 150, 35, 20, Game::State::States::MAIN_MENU);

    manager.addButton(start_button1);
}

void MAIN_GAME_LOOP(sf::RenderWindow w)
{
    while (w.isOpen())
    {
        sf::Event e;
        while (w.pollEvent(e))
        {
            if (e.type == sf::Event::Closed)
            {
                w.close();
            }
        }
        manager.Update(w);
    }
}
 

I have no idea why I get this error, help please?

Please post in the help forum, the description of General Discussions is explicitly "For everything that is not a help request".

You cannot copy sf::RenderWindow, pass it to the function by reference.

I would also avoid #define for constants, global variables and ALL_CAPS for function names...

Sorry.
Well, thanks, I passed it by reference and now it's working. I changed the parameters of those functions from:

void MAIN_GAME_LOOP(sf::RenderWindow w)

to

void MAIN_GAME_LOOP(sf::RenderWindow& w)
