make编译

makefile文件内容如下:

edit : main.o kbd.o command.o
	cc -o edit main.o kbd.o command.o
main.o : main.c defs.h
	cc -c main.c
kbd.o : kbd.c defs.h command.h
	cc -c kbd.c
command.o : command.c defs.h command.h
	cc -c command.c
.PHONY : clean
clean :
	rm edit main.o kbd.o command.o display

defs.h

#define NUM 40


int kbd();
int command()

command.h

#define COMM "command"

command.c

#include <stdio.h>
#include <stdlib.h>
#include "defs.h"
#include "command.h"

int command()
{
	printf("This is command.c\n");
	printf("command[%s]\n", COMM);	

	return 0;
}

kbd.c

#include <stdio.h>
#include <stdlib.h>
#include "command.h"
#include "defs.h"

int kbd()
{
	printf("This is kbd.c\n");
	printf("kbd[%s]\n", COMM);	

	return 0;
}

main.c

#include <stdio.h>
#include <stdlib.h>

#include "defs.h"

int main()
{
	int sum = NUM;
	printf("hello main!!\n");
	printf("main[%d]\n", sum);
	kbd();	
	command();
	
	return 0;
}

刚开始学，没弄明白最后的clean不执行的问题。可以手工make clean 执行
