c==ubuntu+vscode debug redis7源码

新建.vscode文件夹，创建launch.json和tasks.json

{"version": "0.2.0","configurations": [{"name": "C/C++ Launch","type": "cppdbg","request": "launch","program": "${workspaceFolder}/src/redis-cli", // 调试输出的可执行文件"args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "gdb","setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true}],"preLaunchTask": "build", // 用于构建代码的任务名称,"miDebuggerPath": "/usr/bin/gdb" // gdb 的路径（根据你的系统）}]
}

{"version": "2.0.0","tasks": [{"label": "build","type": "shell","command": "make","args": ["redis-cli"],"group": {"kind": "build","isDefault": true},"options": {"cwd": "${workspaceFolder}" // 设置工作目录为根目录},"problemMatcher": []}]
}

如上就可以了，

其实就是先在当前目录执行make redis-cli

然后找到生成的可执行文件，对该可执行文件进行debug

那是怎么根据可执行文件，知道是哪个源文件中的哪一行，应该就是GDB的原理了。

启动，成功进入断点
