1.源文件led_on5.c内容：
2.起始文件start.S内容：
3.自动化编译文件Makefile内容：
4.头文件s3c2440_soc.h内容：
编译过程中出现的问题：
问题1：
[email protected]:~/workbook/hardware/005_LED$ lsled_on5.c Makefile s3c2440_soc.h start.S
[email protected]:~/workbook/hardware/005_LED$ make
arm-linux-gcc -c -o led_on5.o led_on5.c
led_on5.c:10:25: s3c2440_soc.h: No such file or directory
led_on5.c: In function `main':
led_on5.c:19: error: `GPFCON' undeclared (first use in this function)
led_on5.c:19: error: (Each undeclared identifier is reported only once
led_on5.c:19: error: for each function it appears in.)
led_on5.c:25: error: `GPFDAT' undeclared (first use in this function)
Makefile:2: recipe for target 'all' failed
make: *** [all] Error 1
[email protected]:~/workbook/hardware/005_LED$
解决方法：led_on5.c文件中，【#include <s3c2440_soc.h>】改为【#include "s3c2440_soc.h"】
解析：#include <stdio.h> #include "mytest.h "
问题2：
[email protected]:~/workbook/hardware/005_LED$ make
arm-linux-gcc -c -o led_on5.o led_on5.cIn file included from led_on5.c:10:

Makefile:2: recipe for target 'all' failed
make: *** [all] Error 1
[email protected]:~/workbook/hardware/005_LED$
解决方法：屏蔽语句//#ifndef _s3c2440_soc_H
