mac上用cursor/vscode调试root权限进程

对于root权限进程，保底可以用xcode来调试，当然前提是这个进程是debug版的，release版的进程调试不在本文覆盖范围内

xcode易用性远不如vscode/cursor，能在cursor里断点调试那就更方便了

普通进程cursor里直接launch或attach一下就可以直接调试，root权限的进程用curosr直接attach会报错，这时候就可以使用lldb的远程调试来处理了

本质上就是参考下面这篇官方文档

https://lldb.llvm.org/use/remote.html#remote-system

首先在mac上安装lldb

复制代码

brew install lldb

然后把debugserver软链接到lldb-server同一目录下

复制代码

ln -s /Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Resources/debugserver /opt/homebrew/opt/llvm/bin/debugserver

然后以sudo权限运行lldb-server

复制代码

sudo /opt/homebrew/opt/llvm/bin/lldb-server platform --listen "*:1234" --server

剩下在cursor里配一下launch.json设定就可以了，

复制代码

[ 
    {
      "name": "attach lldb",
      "type": "lldb",
      "request": "attach",
      "pid": "${command:pickProcess}",
      "sourceMap": {}
    },
    {
      "name": "attach root process remote lldb port",
      "type": "lldb",
      "request": "attach",
      "pid": "${command:pickProcess}",
      "initCommands": [
        "platform select remote-macosx",
        "platform connect connect://localhost:1234"
      ],
      "sourceMap": {}
    },
    {
      "name": "launch mac program",
      "type": "lldb",
      "request": "launch",
      "program": "${workspaceFolder}/bin/mac/Debug/myApp",
      "args": [      ],
      "cwd": "${workspaceFolder}/bin/mac/Debug/",
      "sourceMap": {}
    }

]

这样就可以很方便的在cursor里attach或launch应用来调试了，而且root权限的进程也同样可以调试，是不是要方便很多
