I need help setting up SDL with Code::Blocks please.

#ifdef __cplusplus    #include <cstdlib>#else    #include <stdlib.h>#endif#include <SDL/SDL.h>int main ( int argc, char** argv ){    // initialize SDL video    if ( SDL_Init( SDL_INIT_VIDEO ) < 0 )    {        printf( "Unable to init SDL: %s\n", SDL_GetError() );        return 1;    }    // make sure SDL cleans up before exit    atexit(SDL_Quit);    // create a new window    SDL_Surface* screen = SDL_SetVideoMode(640, 480, 16,                                           SDL_HWSURFACE|SDL_DOUBLEBUF);    if ( !screen )    {        printf("Unable to set 640x480 video: %s\n", SDL_GetError());        return 1;    }    // load an image    SDL_Surface* bmp = SDL_LoadBMP("cb.bmp");    if (!bmp)    {        printf("Unable to load bitmap: %s\n", SDL_GetError());        return 1;    }        // center the bitmap on screen    SDL_Rect dstrect;    dstrect.x = (screen->w - bmp->w) / 2;    dstrect.y = (screen->h - bmp->h) / 2;    // program main loop    bool done = false;    while (!done)    {        // message processing loop        SDL_Event event;        while (SDL_PollEvent(&event))        {            // check for messages            switch (event.type)            {                // exit if the window is closed            case SDL_QUIT:                done = true;                break;                // check for keypresses            case SDL_KEYDOWN:                {                    // exit if ESCAPE is pressed                    if (event.key.keysym.sym == SDLK_ESCAPE)                        done = true;                    break;                }            } // end switch        } // end of message processing        // DRAWING STARTS HERE                // clear screen        SDL_FillRect(screen, 0, SDL_MapRGB(screen->format, 0, 0, 0));        // draw bitmap        SDL_BlitSurface(bmp, 0, screen, &dstrect);        // DRAWING ENDS HERE        // finally, update the screen :)        SDL_Flip(screen);    } // end main loop    // free loaded bitmap    SDL_FreeSurface(bmp);    // all is well ;)    printf("Exited cleanly\n");    return 0;}
