ubuntu+vscode+c++

在ubuntu 16.04 lsc版本中

>gcc -v

version 5.4.0

>g++ -v

version 5.4.0

使用常规方法不能编译c++，比如例子中的

#include <iostream>
#include <vector>
#include <string>

using namespace std;

int main()
{
    vector<string> msg{"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"};

    for (const string &word : msg)
    {
        cout << word << " ";
    }
    cout << endl;
}

会提示>msg g++98之类的

也就是没有使用g++11来进行编译，这个时候需要在code runner和vscode中设置一下

在vscode中生成的tasks.json中，修改为

"args": [
        "-g",
        "-std=c++11",
        // "${file}",
        "${workspaceFolder}/*.cpp",
        "-o",
        "${fileDirname}/${fileBasenameNoExtension}"
      ],

同理，在vscode的settings中寻找code runner后，选择edit  in settings.json，增加以下json语句

"code-runner.executorMap": {
  
    "javascript": "node",
    "java": "cd $dir && javac $fileName && java $fileNameWithoutExt",
    "c": "cd $dir && gcc $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
    "cpp": "cd $dir && g++ -std=c++11 $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
    "objective-c": "cd $dir && gcc -framework Cocoa $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
    "php": "php",
    "python": "python -u",
    "perl": "perl",
    "perl6": "perl6",
    "ruby": "ruby",
    "go": "go run",
    "lua": "lua",
    "groovy": "groovy",
    "powershell": "powershell -ExecutionPolicy ByPass -File",
    "bat": "cmd /c",
    "shellscript": "bash",
    "fsharp": "fsi",
    "csharp": "scriptcs",
    "vbscript": "cscript //Nologo",
    "typescript": "ts-node",
    "coffeescript": "coffee",
    "scala": "scala",
    "swift": "swift",
    "julia": "julia",
    "crystal": "crystal",
    "ocaml": "ocaml",
    "r": "Rscript",
    "applescript": "osascript",
    "clojure": "lein exec",
    "haxe": "haxe --cwd $dirWithoutTrailingSlash --run $fileNameWithoutExt",
    "rust": "cd $dir && rustc $fileName && $dir$fileNameWithoutExt",
    "racket": "racket",
    "scheme": "csi -script",
    "ahk": "autohotkey",
    "autoit": "autoit3",
    "dart": "dart",
    "pascal": "cd $dir && fpc $fileName && $dir$fileNameWithoutExt",
    "d": "cd $dir && dmd $fileName && $dir$fileNameWithoutExt",
    "haskell": "runhaskell",
    "nim": "nim compile --verbosity:0 --hints:off --run",
    "lisp": "sbcl --script",
    "kit": "kitc --run",
    "v": "v run",
    "sass": "sass --style expanded",
    "scss": "scss --style expanded",
    "less": "cd $dir && lessc $fileName $fileNameWithoutExt.css",
    "FortranFreeForm": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
    "fortran-modern": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
    "fortran_fixed-form": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
    "fortran": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt"
  }

这段代码其实是可以自动生成的，你输入

"code-runner.executorMap":
就能自动补全，然后把里面的"cpp"项的参数改为

"cpp": "cd $dir && g++ -std=c++11 $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt"

 

就可以编译上面那段代码了
