Problem compiling a function from Boost Library

I'm trying to use the function norm_2_vector from boost. But I'm getting the error ‘norm_2_square’ was not declared in this scope. To compile I used the command below, where testNormSquare is the name of the program:

g++ -o testNorm2Square testNorm2Square.cpp

Question: Is there anything I'm missing? What should I do to make the code compilable?

A toy example that is not working is given below.

#include <boost/numeric/ublas/vector.hpp>
#include <boost/numeric/ublas/io.hpp>
int main () {
    using namespace boost::numeric::ublas;
    vector<double> v (3);
    for (unsigned i = 0; i < v.size (); ++ i)
    v(i) = i;
    std::cout << 2.0 * v << std::endl;
    std::cout << v * 2.0 << std::endl;
    std::cout << norm_2_square(v);
}

The error message is the following:

testNorm2Square.cpp:12:18: error: ‘norm_2_square’ was not declared in this scope

Another problem happens if I specify explicitly that norm_2_square belongs to boost::numeric::ublas:

#include <boost/numeric/ublas/vector.hpp>
#include <boost/numeric/ublas/io.hpp>
int main () {
    using namespace boost::numeric::ublas;
    vector<double> v (3);
    for (unsigned i = 0; i < v.size (); ++ i)
        v(i) = i;
    std::cout << 2.0 * v << std::endl;
    std::cout << v * 2.0 << std::endl;
    std::cout << boost::numeric::ublas::norm_2_square(v);
}

In this case the error message is:

testNorm2SquareV2.cpp:12:41: error: ‘norm_2_square’ is not a member of ‘boost::numeric::ublas’
