Boost Network Library not recognized on MAC OSX

Question

So my current code I am trying to compile:

#include <boost/network/protocol/http/client.hpp>

int main()
{
    boost::network::http::client client;

    boost::network::http::client::request request("http://www.example.com");
    request << boost::network::header("Connection", "close");
    boost::network::http::client::response response = client.get(request);

    std::cout << body(response);

    return 0;
}

All code harvested from [this post] (How can I fetch data from a website inside a C++ program). So I've tried running this thing by itself with a few different scripts provided, but none have worked. Here are some of the scripts I've tried:

g++ -I. -I$BOOST_ROOT -L$BOOST_ROOT/stage/lib -lboost_system
g++ -I. -I/usr/local/include/boost -lboost_thread -lboost_system
-lcppnetlib -client -connections -lcppnetlib -server -parsers
-lcppnetlib -uri -pthread main.cpp
./a.out

I have also tried:

g++ -I. -I$BOOST_ROOT -L$BOOST_ROOT/stage/lib -lboost_system -pthread main.cpp

And also tried:

g++ -I. -I/usr/local/Cellar/boost/1.59.0/include/boost -L/usr/local/Cellar/boost/1.59.0/lib -lboost_system pthread main.cpp

But I noticed after reading some more posts that the -I is used to signify the header files for boost in their root directory and the -L is used to find the libraries for the boost root directory. So I am not sure exactly what I've downloaded because I now have 2 copies and I am not sure if either of them work, and I am tried every combination to try to get this thing running. Apparently I have several copies of boost sitting all over the place. So the /usr/local/Cellar directory holds both up to date ones..

/usr/local/Cellar/boost/1.59.0/include/boost

/usr/local/Cellar/boost/1.59.0/include/lib

Also, the /usr/local/ directory holds both..

/usr/local/include/boost/

/usr/local/lib

And again,

/usr/local/opt/boost/include

/usr/local/opt/boost/include/lib

Does having multiple copies disrupt the process or something? I am so confused.

This is my directory structure:

So my I've tried figuring this out and I am simply stumped.. I am not good with scripting (just recently learned most of it from this issue), and I simply do not know how to compile this thing.. Any help is any way, shape, or form is beyond appreciated. Thanks in advance to anyone who helps.

Whatever the library you're using is, it surely is not part of Boost... — ildjarn
Such great insight. My question for you is 'then which library should be included to properly work with boost?' — bmc
If you're looking for the proposed and subsequently rejected Boost.Http library, that can be found here. The only official Boost library that deals with networking is Boost.Asio. Note that Boost.Http was rejected as an official Boost library, but it is still being actively worked on. The code you've shown appears to be for cpp-netlib, which can be found here, and again is not an official Boost library. — ildjarn
cpp-netlib is a high-level abstraction built on top of Boost.Asio; i.e. they serve different purposes, and Asio is the lower-level of the two. Use whichever suits your needs best. — ildjarn

Example was provided for cpp-netlib, which is not part of Boost C++.

But it can be built and installed as addition to your Boost installation as described in README.
