source_location: nichtdeklarierter Bezeichner

Hi,

Mein Visual Studio 2022 erkennt nicht die Klasse source_location (struct?)
Kann man da was tun?
Vielen Dank

#include <iostream>
#include <string_view>
#include <source_location>



void log(const std::string_view message,
    const std::source_location location =
    std::source_location::current())
{
    std::cout << "file: "
        << location.file_name() << "("
        << location.line() << ":"
        << location.column() << ") `"
        << location.function_name() << "`: "
        << message << '\n';
}

template <typename T> void fun(T x)
{
    log(x);
}

int main(int, char* [])
{
    log("Hello world!");
    fun("Hello C++20!");
}

Du musst den Compilerschalter /std:c++20 nutzen.

@SeppJ Danke SeppJ und schönes Wochenende
