根目录下的Makefile文件调用test2中的Makefile文件：
根目录下的Makefile文件


SUBDIR = ./test2


MAKE = make


subsystem:


cd $(SUBDIR) && $(MAKE)



test2中的Makefile文件：


all: ./bin/test




CC = gcc


INCLUDE = ./include


vpath %.c ./src


vpath %.h ./include




./bin/test: hello.o


$(CC) -o $@ $^


hello.o: hello.c hello.h


$(CC) -c $< -I$(INCLUDE)


.PHONY: clean


clean:


-rm *.o
