工程中编写自己的makefile---8 编写Arm开发板的makefile

1 编写开发板的程序的makefile

基于以上的学习，下面编写一个基于Hi3520D开发板的程序

工程目录结构如下

1.1 编写子makefile

相对来说，子makefiled都是相同，

所做的工作就是把子makefile同目录下的所有文件下的.c源文件全部便宜为相应的.o目标文件，然后把所有的.o文件cp到Object目录下；

#$(shell ls -d */) 命令打印当前目录下的所有文件夹

DIRS := $(shell ls -d*/) ./

FILES := $(foreachdirs, $(DIRS), $(wildcard $(dirs)*.c))

OBJS := $(patsubst%.c, %.o, $(FILES))

all:$(OBJS)$(OBJSDIR)

#$(OBJS):%.o:%.c

# $(CC) -c $< -o $@ $(CFLAGS)

#依赖一个伪目标，这样每次编译时因为ALWAYSMAKE不存在，都会执行命令

$(OBJSDIR):ALWAYSMAKE

cp $(OBJS) $(OBJSDIR)

.PHONY:clean

clean:

$(RM) $(OBJS)

.PHONY:ALWAYSMAKE

ALWAYSMAKE:
