[Help-gsl] GSL Ode Example problem: undefined reference

[Łukasz Torbicki]

Hi,
I have some weird problem with ode example from gsl documentation. I use
this code:

[code]
#include <stdio.h>
#include <gsl/gsl_errno.h>
#include <gsl/gsl_matrix.h>
#include <gsl/gsl_odeiv2.h>

int func (double t, const double y[], double f[], void *params)
     {
       double mu = *(double *)params;
       f[0] = y[1];
       f[1] = -y[0] - mu*y[1]*(y[0]*y[0] - 1);
       return GSL_SUCCESS;
     }

     int jac (double t, const double y[], double *dfdy, double dfdt[], void
*params)
     {
       double mu = *(double *)params;
       gsl_matrix_view dfdy_mat = gsl_matrix_view_array (dfdy, 2, 2);
       gsl_matrix * m = &dfdy_mat.matrix;
       gsl_matrix_set (m, 0, 0, 0.0);
       gsl_matrix_set (m, 0, 1, 1.0);
       gsl_matrix_set (m, 1, 0, -2.0*mu*y[0]*y[1] - 1.0);
       gsl_matrix_set (m, 1, 1, -mu*(y[0]*y[0] - 1.0));
       dfdt[0] = 0.0;
       dfdt[1] = 0.0;
       return GSL_SUCCESS;
     }

     int main (void)
     {
       double mu = 10;
       gsl_odeiv2_system sys = {func, jac, 2, &mu};

       gsl_odeiv2_driver * d = gsl_odeiv2_driver_alloc_y_new ( &sys,
gsl_odeiv2_step_rk8pd, 1e-6, 1e-6, 0.0);
       int i;
       double t = 0.0, t1 = 100.0;
       double y[2] = { 1.0, 0.0 };

       for (i = 1; i <= 100; i++)
         {
           double ti = i * t1 / 100.0;
           int status = gsl_odeiv2_driver_apply (d, &t, ti, y);

           if (status != GSL_SUCCESS)
        {
          printf ("error, return value=%d\n", status);
          break;
        }

           printf ("%.5e %.5e %.5e\n", t, y[0], y[1]);
         }

       gsl_odeiv2_driver_free(d);
       return 0;
     }
[/code]

I compile it with additional -lgslcblas -lgsl  -lm parameters.
I've tried reinstalling gsl - both from the ubuntu (I use Natty) and gsl
package - with no effect.

The messages I get are:
/ode_gsl_test/main.cpp:33: error: undefined reference to
`gsl_odeiv2_step_rk8pd'
/ode_gsl_test/main.cpp:33: error: undefined reference to
`gsl_odeiv2_driver_alloc_y_new'
/ode_gsl_test/main.cpp:41: error: undefined reference to
`gsl_odeiv2_driver_apply'
/ode_gsl_test/main.cpp:52: error: undefined reference to
`gsl_odeiv2_driver_free'

Any idea what to do?
