1.安装

安装如下软件：

• VSCode
• clangd 扩展
• mingw-w64

2.配置

配置好 mingw-w64 到用户环境中。

在项目中设置 .clangd 扩展，设置 argument

//setting.json

    "clangd.arguments": [
        "--query-driver=D:\\Development\\Tools\\mingw64\\bin\\gcc.exe"
    ]

然后创建 .clangd 文件进行配置，内容如下

CompileFlags:
  Compiler: gcc.exe

3.结果

clangd 成功解析
