使用VSCode编译C/C++时,会存在找不到头文件的情况这时候需要设置两个地方:

1.c_cpp_properites.json
2.task.json

以下是我修改的对应的文件

{
  "configurations": [
    {
      "name": "Win32",
      "includePath": [
        "${workspaceFolder}/**",
        "${workspaceRoot}",
        "xxx/include"
      ],
      "browse": {
        "path": [
          "${workspaceRoot}",
          "xxx/lib"
        ]
      },
      "defines": [
        "_DEBUG",
        "UNICODE",
        "_UNICODE"
      ],
      "compilerPath": "xxx/gcc.exe",
      "cStandard": "c11",
      "cppStandard": "c++17",
      "intelliSenseMode": "gcc-x64"
    }
  ],
  "version": 4
}
{
  "version": "2.0.0",
  "command": "g++",
  "args": ["-g","${file}","-Lxxx/lib","-Ixxx/include","-o","${fileBasenameNoExtension}.exe"], // 编译命令参数,添加-L,-I选项
  "problemMatcher": {
    "owner": "cpp",
    "fileLocation": ["relative", "${workspaceRoot}"],
    "pattern": {
      "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
      "file": 1,
      "line": 2,
      "column": 3,
      "severity": 4,
      "message": 5
    }
  }
}

附加上launch.json,参考网上的,链接找不到了,感谢原作者。

{
  "version": "0.2.0",
  "configurations": [
    
    {
      "name": "(gdb) Launch", // 配置名称,将会在启动配置的下拉菜单中显示
      "type": "cppdbg",  // 配置类型,这里只能为cppdbg
      "request": "launch", // 请求配置类型,可以为launch(启动)或attach(附加)
      "program": "${workspaceRoot}/${fileBasenameNoExtension}.exe",// 将要进行调试的程序的路径
      "args": [],  // 程序调试时传递给程序的命令行参数,一般设为空即可
      "stopAtEntry": false, // 设为true时程序将暂停在程序入口处,一般设置为false
      "cwd": "${workspaceRoot}",// 调试程序时的工作目录,一般为${workspaceRoot}即代码所在目录
      "environment": [],
      "externalConsole": true,// 调试时是否显示控制台窗口,一般设置为true显示控制台
      "MIMode": "gdb",
      "miDebuggerPath": "xxx\\gdb.exe",// miDebugger的路径,注意这里要与MinGw的路径对应
      "preLaunchTask": "g++", // 调试会话开始前执行的任务,一般为编译程序,c++为g++, c为gcc
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        }
      ]
    }
  ]
}

vscode 添加头文件路径的方法

配置IntelliSense 

扩展程序会根据当前系统环境配置基本信息,因此有可能配置不完整,这时需要通过生成c_cpp_properties.json文件来配置缺少的信息:

ctrl+shift+P打开Command Palette,运行C/Cpp: Edit configurations...生成c_cpp_properties.json:

"includePath": [
        "${workspaceFolder}/**",
        "D:\\ite_sdk\\sdk\\**",
        "D:\\ite_sdk\\openrtos\\**",
        "C:\\ITEGCC\\*"

构建应用程序

如果要构建应用程序,则需要生成tasks.json文件:

Ctrl+Shift+P -> Tasks: Configure Tasks… -> Create tasks.json file from templates -> Others.
