拂曉·明月·彎刀

以下是本人在GNUStep環境下寫的Makfile文件總結：

1. 執行語句前不要有空格，最好以TAB代替空格
2. 變量使用方式是$(CC)，而不是$CC,%CC%等形式

附Makefile文件內容：

CC=gcc
CFLAGS=-fconstant-string-class=NSConstantString -I/GNUStep/System/Library/Headers
CLIBRARY=-L/GNUStep/System/Library/Libraries/ -lobjc -lgnustep-base

Main: Main.o Shape.o CarParts.o Engine.o Tire.o Slant.o AllWeatherRadial.o
$(CC) -o Main Main.o Shape.o CarParts.o Engine.o Tire.o Slant.o AllWeatherRadial.o $(CLIBRARY)

Main.o: Test.m Shape.h Engine.h Tire.h AllWeatherRadial.h Slant.h CarParts.h
$(CC) -o Main.o -c Test.m $(CFLAGS) -std=c99

Shape.o: Shape.m Shape.h
$(CC) -c Shape.m $(CFLAGS) -std=c99

CarParts.o: CarParts.m CarParts.h Engine.h Tire.h
$(CC) -c CarParts.m $(CFLAGS) -std=c99

Engine.o: Engine.m Engine.h
$(CC) -c Engine.m $(CFLAGS)

Tire.o: Tire.m Tire.h
$(CC) -c Tire.m $(CFLAGS)

Slant.o: Slant.m Slant.h Engine.h
$(CC) -c Slant.m $(CFLAGS)

AllWeatherRadial.o: AllWeatherRadial.m AllWeatherRadial.h Tire.h
$(CC) -c AllWeatherRadial.m $(CFLAGS)

clean:
rm -f *.o
rm -f Main.exe
