31.開始分析系统

32．開始安装软件

33.全选全部的选项

C/C++开发

Linux内核驱动开发

37.安装完毕进入界面

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvaXRjYXN0Y3Bw/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="" />

38.写一个C语言的helloworld

39.启动终端

40.进入路径

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvaXRjYXN0Y3Bw/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="" />

41.编译运行

42.写一个C++的代码1,cc

43. 打印语句，C++

44.打印出结果

45. 驱动的helloworld

#include <linux/init.h> //驱动初始化

#include <linux/module.h>//驱动模块

MODULE_LICENSE("Dual BSD/GPL");//遵循linux协议

static int hello_init(void)

{

printk(KERN_ALERT "Hello, world\n");//打印驱动信息

return 0;

}

static void hello_exit(void)

{

printk(KERN_ALERT "Goodbye, cruel world\n");//打印驱动信息

}

module_init(hello_init);//打印驱动初始化信息

module_exit(hello_exit);//打印驱动结束信息

46.q驱动的编译选项，注意all,clean以下的操作前面都要加tab键

pwd = $(shell pwd)

KERNEL_SRC = /lib/modules/$(shell uname-r)/build

obj-m := hello.o

module-objs := hello.o

all:

$(MAKE) -C $(KERNEL_SRC) M=$(PWD) modules

clean:

rm *.ko

rm *.o

47．编译驱动

48 超级管理员载入驱动

49 看到驱动输出

50 卸载驱动，并查看

51驱动退出。

52遍历全部驱动

53. 驱动程序list

54.

这个时候openSUSE CCPP以及Linux内核驱动开发环境搭建完毕，希望大家认真实践。
