Using Boost for reading zip files

[Learned]

This is continuation of previous thread in my quest for getting something to read the zipped folders I have but since the methodology is different I decided to start a new thread.

I installed boost and ran a couple of example programs but this one which could have saved my day is not working:

#include <fstream>
#include <iostream>
#include <boost/iostreams/filtering_streambuf.hpp>
#include <boost/iostreams/copy.hpp>
#include <boost/iostreams/filter/gzip.hpp>

int main() 
{
	using namespace std;

	ifstream file("hello.gz", ios_base::in | ios_base::binary);
	filtering_streambuf<input> in;
	in.push(gzip_decompressor());
	in.push(file);
	boost::iostreams::copy(in, cout);
}

The errors are:

1>c:\: error C2065: 'filtering_streambuf' : undeclared identifier
1>c:\: error C2065: 'input' : undeclared identifier
1>c:\: error C2065: 'in' : undeclared identifier
1>c:\: error C2065: 'in' : undeclared identifier
1>c:\: error C2228: left of '.push' must have class/struct/union

I just copied this code from boost website. Also, it does not give error with the headers as unrecognized headers at all.

So, where is this thing going wrong?
