Jak uruchomić import std; w clang 22.1 i gcc 15.2?

Question

Stosuję te wszystkie opcje, niestety nie działa

g++ -std=c++26 -fmodules -freflection -fsearch-include-path -fmodule-only -c bits/std.cc

 

clang++: warning: argument unused during compilation: '-freflection' [-Wunused-command-line-argument]
<source>:1:8: fatal error: module 'std' not found

import std;

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}
