多层级的makefile编写——递归调用makefile

文件层级结构：

│  Makefile
│  tmp
│
├─include
│      public.h
│
└─src
    ├─moda
    │      Makefile
    │      moda.c
    │      moda.h
    │
    └─modb
            Makefile
            modb.c
            modb.h

public.h

#define MAX_SIZE 10

#include <stdio.h>
#include "moda.h"
#include "public.h"

int main(void)
{
	printf("This is mod A, MAX_SIZE:%d \n", MAX_SIZE);
	return 0;
}

顶层makefile：

CC = gcc

ROOT := $(shell pwd)
INCLUDE := $(ROOT)/include
SRC := $(ROOT)/src

USR_SUB_DIR := $(SRC)/moda $(SRC)/modb

default:usr

usr:
	@for n in $(USR_SUB_DIR); do $(MAKE) -C $$n ; done
	
clean:
	@for n in $(USR_SUB_DIR); do $(MAKE) -C $$n clean; done

CC = gcc

ROOT := $(shell pwd)/../..
INCLUDE := $(ROOT)/include

CFLAGS += -I$(INCLUDE)

target:moda

modb:moda.o
	$(CC) -o moda moda.o

modb.o:moda.c
	$(CC) $(CFLAGS) -c moda.c 
	
clean:
	-rm *.o moda
