odeint simple 1d ode example does not compile

Question

I try to run odeint examples in boost_1_54_0 on Debian Squeeze g++4.4

Lorenz system works fine, but Simple 1d ode:

#include <iostream>
#include <boost/numeric/odeint.hpp>


using namespace std;
using namespace boost::numeric::odeint;


/* we solve the simple ODE x' = 3/(2t^2) + x/(2t)
 * with initial condition x(1) = 0.
 * Analytic solution is x(t) = sqrt(t) - 1/t
 */

void rhs( const double x , double &dxdt , const double t )
{
    dxdt = 3.0/(2.0*t*t) + x/(2.0*t);
}

void write_cout( const double &x , const double t )
{
    cout << t << '\t' << x << endl;
}

// state_type = double
typedef runge_kutta_dopri5< double > stepper_type;

int main()
{
    double x = 0.0; 
    //with the following line commented the program compiles
    integrate_adaptive( make_controlled( 1E-12 , 1E-12 , stepper_type() ) ,
                        rhs , x , 1.0 , 10.0 , 0.1 , write_cout );
}

doesn't compile. There are 192 lines of errors that end with:

/usr/local/include/boost/numeric/odeint/algebra/range_algebra.hpp:76: error: no matching function for call to ‘begin(double&)’

What's the problem?

The example on the webpage is only running with the github version of odeint. If you change the stepper type to

typedef runge_kutta_dopri5< double , double , double , double , vector_space_algebra > stepper_type;

it should run. We have included a automatic algebra detection mechanism which is not in the official boost version but which will be included very soon.
