The GCC compiler has an error even though the path is passing.

Here's the program.

#include<stdio.h> 

int main(void){
    printf("Hello world!"); 
    return 0;
}　

The error was long, so I put it here.

It's not that I don't have a header file, so I think it's passed, but I've been thinking about and running some sites since yesterday, but I can't get an executable file.Could you please help me?

I am also asking for an answer.https://teratail.com/questions/119490
