Look carefully at the gcc manual and the options to g++, the '-I'
option, which may be used multiple times, gives a path to search for
include files.

Now, I can't help the warning at the moment, but the show stoppers are
the undefined references which are probably defined in the missing
libraries you asked for on the line:

LIBS=`sdl-config --cflags --libs` -lSDL_image -lSDL_gfx -lSDL_ttf

You probably need to add one or more '-L' options which you use to
tell gcc where to find libraries (for details, see the gcc manual).
