Ok so I dod the SDL install
sudo apt-get install libsdl1.2-dev libsdl-image1.2-dev libsdl-gfx1.2-dev libsdl-ttf2.0-dev

sudo nano test.c

copy

#include <SDL/SDL.h>

int main(int argc, char** argv) {
SDL_Init(SDL_INIT_EVERYTHING);
SDL_Surface *screen;

screen = SDL_SetVideoMode( 480, 320, 16, SDL_SWSURFACE );
SDL_Rect rect;
rect.x = 10;
rect.y = 10;
rect.w = 20;
rect.h = 20;

Uint32 color = SDL_MapRGB(screen->format, 0xff,0xff,0xff);
Uint32 color2 = SDL_MapRGB(screen->format, 0,0,0);
SDL_FillRect(screen, &screen->clip_rect, color);
SDL_Flip(screen);
getchar();

SDL_Quit();
return 0;
}

gcc -o test test.c sdl-config –cflags sdl-config –libs

Get error:-
