Very weird, i will give you the source code here:

//The headers
#include “SDL/SDL.h”
#include
using namespace std;

//Attributes of the screen
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;
const int SCREEN_BPP = 32;

//Surfaces that will be used
SDL_Surface *message = NULL;
SDL_Surface *background = NULL;
SDL_Surface *screen = NULL;

//Load the images
SDL_Surface load_image(string filename)
{
//Temporary storage for the image that’s loaded
SDL_Surface loadedImage = NULL;

//The optimized image that will be used
SDL_Surface* optimizedImage = NULL;

//Load the image
loadedImage = SDL_LoadBMP(filename.c_str());

if(loadedImage != NULL)
{
	//Optimized Image Creating
	optimizedImage = SDL_DisplayFormat(loadedImage);
	SDL_FreeSurface(loadedImage);
}

return optimizedImage;

}

void apply_surface(int x, int y, SDL_Surface* source, SDL_Surface*
destination)
{
//Make a temporary rectangle to hold the offsets
SDL_Rect offset;

//Give the offsets to the rectangle
offset.x = x;
offset.y = y;

//Blit the surface
SDL_BlitSurface(source, NULL, destination, &offset);

}

int main(int argc, char* args[])
{
//Initialize all SDL subsystems
if(SDL_Init(SDL_INIT_EVERYTHING) == -1)
{
return 1;
}

//Set up the screen
screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP,

SDL_SWSURFACE );

//If there was in error in setting up the screen
if(screen == NULL)
{
	return 1;
}

//Set the window caption
SDL_WM_SetCaption( "Hello World blaat", NULL );

//Load the images
message = load_image("hello_world.bmp");
background = load_image("background.bmp");

//Apply the background to the screen
apply_surface(0, 0, background, screen);

//Apply the message to the screen
apply_surface(180, 140, message, screen);

//Update the screen
if(SDL_Flip(screen) == -1)
{
	return 1;
}

//Wait 2 seconds
SDL_Delay(2000);

//Free the surfaces
SDL_FreeSurface(message);
SDL_FreeSurface(background);

//Quit SDL
SDL_Quit();

//Return
return 0;

}

I hope you guys can fix it for me, bye :wink:
