'g++' is not recognized as an internal or external command, operable program or batch file.

Question

I am trying to set up the VScode with C++ Compiler By following this tutorial enter link description here

and the problem I got is (By running the code with code runner)

'g++' is not recognized as an internal or external command, operable program or batch file. enter image description here

and if I run with the debug option I got this problem

The preLaunchTask 'build & run file' terminated with exit code 1.enter image description here

This is my "c_cpp_properties.json"

}

This is my "launch.json"

{
  "version": "0.2.0",
  "configurations": [
    {

        }
      ],
      "preLaunchTask": "build & run file"
    },
    {
      "name": "Debug C/C++",
      "type": "cppdbg",
      "request": "launch",
      "program": "${workspaceFolder}/${fileBasenameNoExtension}.exe",

        }
      ],
      "preLaunchTask": "build & debug file"
    }
  ]
}

And this is my "tasks.json"

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "build & debug file",
      "type": "shell",
      "command": "g++",
      "args": [
        "-g",
        "-o",
        "${fileBasenameNoExtension}",
        "${file}"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      }
    },
    {
      "label": "build & run file",
      "type": "shell",
      "command": "g++",
      "args": [
        "-o",
        "${fileBasenameNoExtension}",
        "${file}"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      }
    }
  ]
}

I just want to study C++ and I try a lot of way on the Internet for days and I still can't fix it Please help. Thank you.

Solution 1

You have to add g++ to your PATH variable.

First, find out if you have installed g++ and find where it is located.

You have not mentioned what OS you are using. If you are using Windows, it may be located in C:\mingw or C:\Program Files\mingw.

If you haven't installed g++, you can install it via https://sourceforge.net/projects/mingw-w64/

Then open System Properties -> Advanced -> Environment Variables.

Then under Environment Variables for <username> choose PATH and click on Edit.

Click on New and then click on Browse and find the bin directory in your mingw installation and add that to the path and you're done.

Restart VSCode if you have it open and it would automatically find g++.

Solution 2

[Sloved] I had the same problem and I solved it:

Simply add a new path as: "C:\MinGW\bin\g++.exe"
Now reopen your VS code and you are done:

Possible duplicate of 'g++' is not recognized as an internal or external command, operable program or batch file

[paxdiablo]

Re "command": "g++", you may want to include the full location (including directory) there, unless you're sure the directory that contains it actually is in your standard path.

[S.Xu]

Ken White That post doesn't help me out.

[Donald Duck]

Does this answer your question? "g++" is not recognized as an internal or external command, MinGW

[paxdiablo]

Given they're using MinGW (Minimalist GNU for Windows), it's a reasonably safe bet they're on Windows :-)

[JarMan]

Did you post a link to your personal copy of the mingw installer? Why not post a link to the official [mingw ](mingw.org) page?

[JarMan]

Not a good idea. I wouldn't trust an executable that didn't come from an official source.

It is better to avoid passing external links in an answer. If you are going to refer to external resources, please also give an outline of what is described in the external reference you are referencing.
