# Hello World (Windows)

Overview

A minimal configuration is shown for compiling a simple "Hello World" application on Windows.

This examples illustrates:

- Compiling a directory of cpp files
- Linking those object files into an Executable
- Linking against the standard libraries

To make the sample easier to understand, it is more verbose than is required.
Code (main.cpp)
#include "stdio.h" int main(int, char[]) { printf( "Hello!\n" ); return 0; }
