例一：

TARGET=helloworld CC=gcc CFLAGS=-Wall -O -g SRC=$(wildcard *.c) #所有的.c文件 OBJS=$(patsubst %.c,%.o,$(wildcard *.c)) $(TARGET):$(OBJS) $(CC) $(CFLAGS) $(OBJS) -o $@ # $(RM) *.o %.o: %.c $(CC) $(CFLAGS) -c $< -o $@ clean: rm -rf *.o helloworld

例二：

VPATH= OBJECTS=mmain.o ./pchild/pchild.o TARGET=mm CC=cc all:$(TARGET) $(TARGET):$(OBJECTS) $(CC) $(OBJECTS) -o $@ rm -f $(OBJECTS) mmain.o:mmain.c $(CC) -c $< -o $@ pchild.o:pchild.c pchild.h $(CC) -c $^ -o $@

例三：

VPATH=
OBJECTS=mmain.o ./pchild/pchild.o
YESNO=NO
ifeq ($(YESNO),YES)
TARGET=mm
else
TARGET=nn
endif
CC=cc
all:$(TARGET)
$(TARGET):$(OBJECTS)
$(CC) $(OBJECTS) -o $@
rm -f $(OBJECTS)
