C++ :: Ball Collecting Game - EXE Not Running Outside Code Blocks

I have created a game.It is working fine in codeblocks, but when I am trying to run it outside codeblocks, it opens and closes immediately. I have pasted all the necessary files and dlls in root folder and debug folder. Here is the code:-

#include <iostream>
#include <SDL/SDL_mixer.h>
#include <SDL/SDL.h>
#include <SDL/SDL_ttf.h>
#include <sstream>

const int WINDOWS_Height = 480;
const int WINDOWS_Width = 640;
