OK, Using the following Makefile:
CC=g++
CFLAGS=-W -Wall -pedantic
LIBS=`sdl-config --cflags --libs` -lSDL_image -lSDL_gfx -lSDL_ttf
character.o: character.cpp
reset; $(CC) $(CFLAGS) -c character.cpp;rm *~
battle.o: battle.cpp
reset; $(CC) $(CFLAGS) -c battle.cpp -I/usr/include/SDL/SDL.h; rm *~
all: battle.o character.o
reset; $(CC) $(CFLAGS) battle.o character.o $(LIBS) -o battle; rm *~
When I try to make battle, I get this:
cc1plus: error: /usr/include/SDL/SDL.h: not a directory
g++ battle.o -o battle
g++: battle.o: No such file or directory
g++: no input files
make: *** [battle] Error 1
No battle.o . When I try it without the SDL.h at the end of the -I
option, I get this:
