//complie way

MODULE_FLAGS=-g -std=c++20 -fmodules-ts -x c++ -c
 g++ ${MODULE_FLAGS} num.ixx
 g++ ${MODULE_FLAGS} random.ixx

//issue

1 . i dont know what happened since i add flag:-g
2 . before that , there still have issue :
 when i import random to use the function random_num(range) , when i step : std::random_device rd;
a error occasion from bit/string.h? but i cant formally use random_device in header system project?
