How do I statically include a library in g++?

Question

As mentioned in the title, this is a real beginner's question.

I'm realizing that after several years of CS courses and projects and such, I have never actually needed to export an executable that someone else could run without compiling the source manually (which is what most/all professors/TAs do, since they want to see your source code anyway).

So my question is basically this:

When I compile some basic C++ code (e.g. "Hello World" code), I always seem to need some sort of external DLLs to run it.

• Visual Studio needs the .NET framework.
• Cygwin needs Cygwin.dll.
• MinGW needs libgcc_s_dw2-1.dll or something similar.

So how do I simply compile an executable such that I (or someone I give the file to) can just double-click it and have it run? I'm guessing there are some fancy command line flags I can use on g++ to statically link the DLLs; I have simply never needed to do this before.

As I said twice, this is a super beginner question, and yet I could not find (easily, anyway) an answer to this question, StackOverflow or anywhere else. Largely, I think, because the search terms are so commonly used in the descriptions for other problems.

Anyway, all help is appreciated.

EDIT:

I'm literally talking about a Hello World program. e.g.:

HelloWorld.cpp:

#include <iostream>
using namespace std;

int main()
{
    cout << "Hello World!" << endl;

    return 0;
}

Try g++ -static -static-libgcc
