搭建vscode阅读linux代码环境

vscode插件：

vscode配置：

编译linux内核代码，使用参数O指定编译文件存放路径: O=out/

生成compile_commands.json：最新内核版本 scripts/gen_compile_commands.py -d out/

vscode 打开内核代码所在的文件夹。然后手动创建文件夹.vscode。创建文件c_cpp_properties.json和settings.json

c_cpp_properties.json文件内容配置如下，mac和win可能配置有些不太一样。

{ "configurations": [ { "name": "Linux", "includePath": [ "${workspaceFolder}/**" ], "defines": [ "__KERNEL__" ], "compilerPath": "/usr/bin/gcc", "cStandard": "c11", "cppStandard": "c++17", "intelliSenseMode": "clang-x64", "compileCommands": "${workspaceFolder}/out/compile_commands.json" } ], "version": 4 }

当vscode将文件解析完成后，vscode的右下角会出现一个圆柱体的图标
