No, as I said there are no compile errors no runtime errors and nothing on the terminal. And I checked sf::Texture::loadFromFile() does it's job, but program terminates before main loop somehow.

I've simplify it trying(deactivating-activating) line by line. And I got this:

#include<SFML/Graphics.hpp>
#include<fstream>

int main()
{
        std::ofstream record( "Records/file.txt" );
    sf::RenderWindow mainWindow;
    sf::Event event;
    sf::Texture BGTexture;
    sf::Sprite Background;
    sf::Clock clock;

    mainWindow.create( sf::VideoMode::getDesktopMode(), "Moving Arrows" );
    mainWindow.setVerticalSyncEnabled(true);

    [b]BGTexture.loadFromFile("Background.jpg");[/b]
    Background.setTexture( BGTexture );

    if( mainWindow.isOpen() )
    {
        mainWindow.pollEvent( event );
        mainWindow.clear( sf::Color::Black );
        mainWindow.display();
        clock.restart();

        while( event.type != sf::Event::Closed )
        {
                        mainWindow.pollEvent( event );

                        mainWindow.clear( sf::Color::Black );
                        mainWindow.draw(Background);
                        mainWindow.display();
                        record<<"X";
                }

                mainWindow.close();
                record.close();
        }
        return 0;
}
 

This works on Windows, but when try it on Ubuntu it acts same as before. The problem is with sf::Texture::loadFromFile() function. When I delete it(or either std::ofstream) it works as it suppossed to be.
Of course shows a black screen.
On the other hand, I tried deleting same function from the main file(and from the arrow.hpp) and same problem kept occuring on Ubuntu.
I guess I will be working with Windows for now, when I have time I'll try to solve that problem with Ubuntu.

General / I can't use std::ofstream

I'm trying to make an animation of moving arrows and I need to keep record of time, in a text file, how much arrows stays visible on the screen. But when I write(and not even use that variable):

std::ofstream record;

It compiles without an error but screen shows up and closes immediately. It shows one frame but never gets into main loop. But when I delete only that line everything else works fine.
I suspected namespace members overlapping somehow but that's not the issue.I tried on Windows 7 x64 with CodeBlocks+mingw(GCC 4.8.1) and on Ubuntu 15.04 x64 with gcc 5.1.0.
I tried with a simple program (one that is here bottom of the page : http://www.sfml-dev.org/tutorials/2.3/start-cb.php) and added that the lines that I'm trying to use to write to a text file,only with a random string, and it works.
There are a little too much code so I didn't paste it all here and couldn't simplify it but I'm adding the files as an attachment.
This is how I compile if it's relevant:

g++ -std=c++11 -Wall -Wextra -Werror main.cpp -lm arrow.hpp -lsfml-graphics -lsfml-window -lsfml-system

I really need to keep the records and if there is another way of doing it, I'd like to know.
