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
$make grade
