上次那个虽然能完成基本的编译功能了，但是还是太low啦，今天来优化一下，找到一篇感觉不错的文章，我们来学习一下，依旧是配合linux源码的makefile框架，只是这次会参考一下上面链接的思想。

其实他用的也是linux的makefile的管理思想编译进行层层调用。

clean:

rm -f $(OUTPUT) $(APP_OBJS) $(SHOW_OBJS) $(HARDWARE_OBJS)

FORCE:

$(Q)echo "Forcing target"

.PHONY: FORCE clean all

上面就是目前的makefile

学习和修改

咱们的工程其实不需要那么复杂的编译框架，一个makefile就够了，但是我们要标准化一些，把能拿走的都放到配置文件里。

这个up用的是这种方式，直接把大家的配置文件都放到一起在主makefile那里，

我们就都放到build目录下，一个配置文件，一个共用函数文件

刚刚新加个hardware的rm上面忘记改了直接给我把主函数删了，人麻了，还好vscode有缓存

MAJOR = 0
MINOR = 0
PATCH = 0
NAME = tianyu.xin

include ./make_conf.mk 

all: $(OUTPUT)
#	$(Q)$(CURDIR)	

include ./make_fun.mk

clean:
	rm -f $(OUTPUT) $(APP_OBJS) $(SHOW_OBJS) $(HARDWARE_OBJS)

FORCE:
	$(Q)echo "Forcing target"

.PHONY: FORCE clean all

修改后makefile文件就变成这样了

这俩makefile的头文件把之前配置的东西都拿走了。

然后试一试昨天加的打印编译过程功能

在试试我新加的功能

我把clean命令拆成了两个全部清除和只清除中间文件

然后我把所有的中间文件和目标文件都放到了OUTPUT目录下

现在代码可以进一步简化了

有的文件单纯就是描述文件没有.o文件所以会导致mv的时候报错

2>/dev/null

可以用这个把标准错误定向到空

现在代码还有个问题就是我们的执行只能在build目录下，所以们在优化一下

ROOT_DIR = ..
OUTPUTFILE = $(ROOT_DIR)/OUTPUT

然后我们再来加个打印头

# Silent printing is always required here
show:
	@echo "--------------------------------------------------------------"
	@echo "----------------------Build Start-----------------------------"
	@echo "--------------------------------------------------------------"
	@echo "Version: $(MAJOR).$(MINOR).$(PATCH)\n"
	@echo "Author: $(NAME)\n"

还有颜色输出

这个可以参考我之前的一个文章设置对应颜色

http://t.csdnimg.cn/9dUHY

ifeq ($(filter debug,$(MAKECMDGOALS)),1)
	DEBUG = -g
else
	DEBUG = 
endif

CC = gcc
CFLAGS = -Wall -Werror $(DEBUG) $(INCLUDE)

现在有一个问题我像上面这样定义没有效果，像下面这样就可以

ifeq ($(filter debug,$(MAKECMDGOALS)),1)
	CFLAGS = -Wall -Werror -g $(INCLUDE)
else
	CFLAGS = -Wall -Werror $(DEBUG) $(INCLUDE)
endif

CC = gcc

算了debug和waring的开关问题留到下次解决好了
