VSCode C++ 跨文件跳转失效_C/C++

vscode 搭配 cmake+mingw 开发 c++，程序编译运行一切正常，但是 ctrl 点击函数调用无法跳转定义。

1、安装微软官方 c/c++ 扩展 ms‑vscode.cpptools

2、cmake 开启导出编译数据库 cmake_export_compile_commands

3、配置 .vscode/c_cpp_properties.json

原来是这样：

{
  "configurations": [
    {
      "name": "windows-gcc-x64",
      "includepath": [
        "${workspacefolder}/**"
      ],
      "compilerpath": "c:/program files (x86)/mingw64/bin/gcc.exe",
      "cstandard": "${default}",
      "cppstandard": "${default}",
      "intellisensemode": "windows-gcc-x64",
      "compilerargs": [
        ""
      ]
    }
  ],
  "version": 4
}

改成：

{
  "configurations": [
    {
      "name": "windows-gcc-x64",
      "includepath": [
        "${workspacefolder}/**"
      ],
      "compilerpath": "c:/program files (x86)/mingw64/bin/g++.exe",
      "cstandard": "c17",
      "cppstandard": "c++23",
      "intellisensemode": "windows-gcc-x64",
      "compilecommands": "${workspacefolder}/compile_commands.json"
    }
  ],
  "version": 4
}

4、重载 vscode 窗口，重建 intellisense 索引

ctrl+shift+p → developer: reload window ,重载窗口
