4. 修改完毕后，编译实验代码
|

```

$make
|

```
|

```
|

5. 如果编译无误，则可以运行测试一下
|
||||
```
|
||||
$make qemu
|
||||
```
|
||||
6. 可以运行如下命令，看看自己的得分
|
||||
|
||||
6. 如果需要调试，
|
||||
a. 可基于cgdb的字符方式(以lab1_ans为例)
|
||||
```
|
||||
$cd labcodes_answer/lab1_ans
|
||||
$make debug
|
||||
```
|
||||
可以看到弹出两个窗口，一个是qemu,一个是cgdb
|
||||
可以看到在bootloader的bootmain函数处停了下来。
|
||||
然后我们就可以进一步在cgdb中用gdb的命令进行调试了
|
||||
```
|
||||
(gdb)file bin/kernel #加载ucore kernel的符号信息
|
||||
(gdb)break kern_init #在函数kern_init处（即 0x100000地址处）设置断点
|
||||
(gdb)continue #继续执行
|
||||
```
|
||||
这时就可以看到在kern_init处停了下来，可进一步调试。
|
||||
|
||||
b. 基于eclipse-CDT的debug view进行调试，如果安装了zylin debug插件，则完成初步配置后，
|
||||
也可很方便地进行调试。
|
||||

||||
7. 可以运行如下命令，看看自己的得分
