Why is VSCode using Cygwin to build and execute my CPP programs?-CodePudding

I downloaded and installed MinGW under C:\MinGw and installed g and gcc.

If I run g --version I get:

g  .exe (MinGW.org GCC-6.3.0-1) 6.3.0

If I run gcc --version, I get:

gcc (GCC) 11.3.0

I'm trying to run a simple helloworld.cpp file from VSCode:

#include<iostream>

int main()
{
    std::cout << "Hello World" << std::endl;
}

I've edited the c_cpp_properties.json file as follows:

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "C:\\MinGW\\include"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "compilerPath": "C:\\MinGW\\bin\\g  .exe",
            "cStandard": "c17",
            "cppStandard": "c  17",
            "intelliSenseMode": "windows-gcc-x64"
        }
    ],
    "version": 4
}

But when I go and build/run the file, I get the following:

Starting build...
C:\cygwin64\bin\cpp.exe -fdiagnostics-color=always -g C:\Users\Pippo\Desktop\Programming\CPP\helloworld.cpp -o C:\Users\Pippo\Desktop\Programming\CPP\helloworld.exe
cpp: fatal error: cannot execute 'cc1plus': spawn: No such file or directory
compilation terminated.

Build finished with error(s).

Why is this failing? And why am I seeing Cygwin being called??

EDIT (more stuff I don't get):

The behaviour I showed before happens when I click on Run C/C File

But when I click on Run Code it works (and it calls g ):

EDIT (@Yakk - Adam Nevraumont answer): Nope, Cygwin is after g in my env vars:

CodePudding user response：

VSCode uses a completely separate tool chain for compiling and for linting and syntax highlighting and similar.

c_cpp_properties.json isn't for compiling.

It gets the compiler typically from your PATH. See here.

Your build task is probably set to the compiler g , and the first one on the search path (the PATH environment variable) is Cygwin's g .
