cppcheck seems to work but no lint results appear (Subilme Text 3, Mac)

I'm using Sublime Text 3(Version 3.1.1, build 3176) on macOS High Sierra(Version 10.13.3).

I want to make SublimeLinter-cppcheck plugin & cppcheck work in my Sublime Text 3, so I installed them according to this link and other web sites.

Now my SublimeLinter.sublime-settings is like this. (I also use the plugin for Python, so there are settings for flake8.)

{
  "debug": true,
  "linters": {
    "cppcheck": {
      "@disable": false,
      "source": "source.cpp",
      "lint_mode": "save",
      "args": [],
      "enable": "style",
      "excludes": [],
      "std": ["c++11"]
    },
    "flake8": {
      "@disable": false,
      "source": "source.py",
      "args": ["--ignore=E111"],
      "enable": "style",
      "excludes": [],
    }
  },
}

Then I check whether they were successfully installed or not with test.cpp which is shown below.

#include <iostream>

using namespace std;

int main()
{
    cout << "it works" << endl;

    return 0;

This code has apparently an error, so if they were successfully installed, some lint results will appear in the code.

In the debug console, cppcheck seems to be working, so I think I succeeded to install it. Here is the output of debug console.

However, no lint result is appear in editing window.

I don't know why lint results don't appear. Where did I made mistakes?

I know that cppcheck doesn't work when lint_mode is background(Related issue). is it related to this strange behavior?

In my environment, finally I solved this problem with deleting the section below from SublimeLinter.sublime-settings.

"cppcheck": {
  "@disable": false,
  "source": "source.cpp",
  "lint_mode": "save",
  "args": [],
  "enable": "style",
  "excludes": [],
  "std": ["c++11"]
},

Now my SublimeLinter.sublime-settings is shown below.

{
  "debug": true,
  "linters": {
    "flake8": {
      "@disable": false,
      "source": "source.py",
      "args": ["--ignore=E111, E114"],
      "enable": "style",
      "excludes": [],
    }
  },
}
