須要安裝的擴展 C/C++
linux

若是是遠程 Linux上開發還須要安裝 Remote Developmentshell

建立工做目錄後,代碼遠程克隆... 省略..json
建立項目配置文件,主要的做用是代碼智能提示,錯誤分析等等...
按F1,輸入 C/C++ 選擇編輯配置UI或者json 這個操做會生成 .vscode/c_cpp_properties.json 配置文件ui

修改相關的參數,如頭文件路徑,預約義參數,編譯器等spa

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**" // 包含了當前工做下全部頭文件,若是沒有在該目錄下須要引入
            ],
            "defines": [ // 這裏是項目中須要的預約義 LINUX環境一般須要加LINUX
                "LINUX",
                "ACI_TEST"
            ],
            "compilerPath": "/usr/bin/g++", // 編譯器程序
            "cStandard": "gnu99",
            "cppStandard": "gnu++14",
            "intelliSenseMode": "linux-gcc-x64"
        }
    ],
    "version": 4
}

(注意) 這個配置文件與編譯和執行沒有任何關係,它僅僅用於代碼提示和錯誤提示debug

代碼編譯和調試配置
選中打開一個.c 或者 .cpp 文件,按F5 選擇環境和編譯器

生成了2個文件3d

.vscode/launch.json調試

這個文件就是怎麼去編譯你的程序,沒什麼可說 , make 或者 gcc g++ 編譯
貼一個個人項目 tasks 用make 編譯orm

{
    "tasks": [
        {
            "type": "shell",
            "label": "make_1",
            "command":"make -j6 -f makefile_local.mk 2>build_error.log",
            "options": {
                "cwd": "${workspaceFolder}/UnitTesting/"
            },
            "problemMatcher": []
        },
        {
            "type": "shell",
            "label": "make_2",
            "command":"make -j6 -f makefile_local.mk 2>build_error.log",
            "options": {
                "cwd": "${workspaceFolder}/"
            },
