can't compile code from Bjarne Stroustrup's Programming C++ book - c++

Question

code is like:
// #include "..\std_lib_facilities.h"
#include "Simple_window.h"
#include "Graph.h"
using namespace Graph_lib;
int main()
{
Point t1 {100, 100};
Simple_window win {t1, 600, 400, "Canvas"};
win.wait_for_button();
}
Simple_window.h and Graph.h is headers Stroustrup made himself. download from www.stroustrup.com
I installed fltk (mingw64/mingw-w64-x86_64-fltk 1.3.5-1) using msys in Windows10.
As I tried, fltk-config doesn't work in windows10 cmd, so I'm using msys to use fltk.
error is like:
hendr#DESKTOP-DC4NCDT MSYS /d/home/prog/cpp/gui
$ fltk-config --compile First.cpp

Is this error due to Simple_window.h, Graph.h or fltk or I'm trying this in Windows10 than linux?
I'm barely newby to c++ so fixing headers from book is impossible job for me..
Is anyone who tried this?
