gcc 7.2.0 failed with cstdlib:75:15: fatal error: stdlib.h: No such file or directory on a hello-world program

[Tim]

Hi,

I have the following program test.cpp:

#include<iostream>
using namespace std;
int main(int argc, char* argv[]) {
  cout << "hello\n"; 
}

And I was trying to compile it with g++ 7.2.0: g++ test.cpp -o test and I
got:

Here’s g++ -v:

I’m not sure if I had gcc compiled correctly. Can anyone help here?

Thanks,
