前言

在上一篇文章

1	`https://bbs.kanxue.com/post-update-1816593.htm`

中介绍了在ubuntu24上编译和调试qemu 0.10.6，本文介绍如何使用这个qemu和vs code配合来调试linux0.11。

linux 0.11下载

1	`https://github.com/yuan-xy/Linux-0.11`

修改Makefile

start:
        @qemu -m 16M -boot a -fda Image -hda $(HDA_IMG)
 
debug:
        @echo $(OS)
        @qemu -m 16M -boot a -fda Image -hda $(HDA_IMG) -s -S

需要注意的是在编译完qemu 0.10.6后一定要

1	`make install`

不然会找不到qemu。这里使用的是qemu实际是qemu-system-i386。使用qemu-system-x86_64，vs code调试会出错。

启动qemu

在Linux-0.11-master目录下执行

make

编译完成后

1	`make debug`

启动qemu

配置vs code

使用vs code，ssh登录ubuntu后，打开Linux-0.11-master目录，新建.vscode/launch.json
