VSCode C++ error, getting "cannot open source file "string_view". | C++ | Page 1

#

I am getting an intellisense highlight/pop up error
"cannot open source file "string_view". Please run the 'Select IntelliSense Configuration...' command to locate your system headers.C/C++(1696)"
although i did fixed the compiler path, set the language standard to c++17, still getting this error.
Its only happening for MinGW compiler but when i select the Intellisense Configure as cl.exe from MSVC the error isnt highlighted but still the program doesn't run, i am new to vs code environment specifically and i believe the some of the json file settings have been changed, cant figure out what.

heres my
cpp_properties.json file contents

{
    "configurations": [
        {
            "name": "windows-g++-x64",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "cStandard": "c17",
            "cppStandard": "c++17",
            "intelliSenseMode": "windows-gcc-x64",
            "compilerArgs": [
                ""
            ]
        },
        {
            "name": "windows-gcc-x64",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.22621.0",
            "compilerPath": "cl.exe",
            "cStandard": "c17",
            "intelliSenseMode": "windows-msvc-x64"
        }
    ],
    "version": 4
}

Any help would be appreciated

Yes, you have to start the dev cmd prompt for vs

#

and start vscode with code .

#

this will start vscode in your current dir

open mural Jan 11, 2024, 3:17 PM

unreal cliff Jan 11, 2024, 3:24 PM

#

Are you sure that you did run vscode with the Developer Command Prompt for Visual Studio?

#

If so, then try to navigate directly in the prompt to your projects folder and then enter code ., im not sure if that makes any difference

open mural Jan 11, 2024, 3:26 PM

#

ohh wait i didnt
lol
now i tried

unreal cliff Jan 11, 2024, 3:26 PM

#

okay, and did it work? 🤨

open mural Jan 11, 2024, 3:27 PM

#

nah now when i try to run via cl.exe it open launch.json

unreal cliff Jan 11, 2024, 3:28 PM

#

open mural nah now when i try to run via cl.exe it open launch.json

but intellisense is working, right?

open mural Jan 11, 2024, 3:28 PM

#

yea itellisense is not giving any error

#

its just when i try to run

#

it gives the same error

unreal cliff Jan 11, 2024, 3:28 PM

#

Choose Àdd Debug Configuration and cl.exe

#

And delete your old launch.json, since this will create a new one

open mural Jan 11, 2024, 3:31 PM

#

i deleted launch.json
then did add debug config -> cl.exe
it opened launch.json

#

when i run it gives error
i think its using g++ to run the code

#

instead of clang

unreal cliff Jan 11, 2024, 3:32 PM

#

Share the json
