g++.exe: installation problem, cannot exec `as': No such file or directory - c++

Question

I'm trying to learn C++, I downloaded and installed g++ on Windows using Cygwin, following this tutorial:
https://www.cs.odu.edu/~zeil/cs250PreTest/latest/Public/installingACompiler/#installing-the-mingw-compiler
Just like in the tutorial, at the end, I check that g++ is installed:
PS D:\Desktop\coursera_ODS_in_c-\Week 2> g++ --version
g++.exe (GCC) 3.4.5 (mingw-vista special r3)
Copyright (C) 2004 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
and then I try to run this code:
#include <iostream>
int main() {
int num = 7;
std::cout << "Values:" << num << std::endl;
std::cout << "Address: " << &num << std::endl;
return 0;
}
by using this
PS D:\Desktop\coursera_ODS_in_c-\Week 2> g++ main.cpp
but I get this:
g++.exe: installation problem, cannot exec `as': No such file or directory
Do you how to solve this ?

Answer 1

The message:
g++.exe: installation problem
clearly states that something's wrong with the installation of your G++ compiler. Also, 3.4.5 version is too old. The current stable release is 10.2 (released on July 23, 2020), reinstalling it with the latest version will probably solve your issue. (Since insufficient details are given, the error cause is still a mystery.)
Try downloading the GNU GCC compiler which comes with the latest edition: GNU GCC.
OTOH, the program is coded properly, no error reported on OnlineGDB.
