Implementing a scroller in SDL graphics

in this part:
---
scroll_surface = SDL_DisplayFormat(tmp);


SDL_FreeSurface(tmp);
---
The line:
---
temp_surface = SDL_DisplayFormat(tmp);
---
is missing.

The correct code should be:
---
scroll_surface = SDL_DisplayFormat(tmp);
temp_surface = SDL_DisplayFormat(tmp);

SDL_FreeSurface(tmp);

Instructions for compling would be helpful. Something like this works:

cc -I/usr/local/include/SDL -c scroll.c
cc -o scroll scroll.o -lSDL -lSDL_image

("locate SDL.h" and "locate SDL_image.h" tell you if you have them and what to include)

Doh - I made a obvious mistake - hey I need an image file called img.pcx (but it don't really have to be pcx. I just renamed an png).

Fun demo.
