Hello all,
I am modifying step-33 to introduce MeshWorker. Since this needs other class
variables, I am trying to use boost::bind to bind the class pointer. Here is
the main stuff:
class ConservationLaw
{
...
typedef dealii::MeshWorker::DoFInfo<dim> DoFInfo;
typedef dealii::MeshWorker::IntegrationInfo<dim> CellInfo;
static void integrate_cell_term (DoFInfo& dinfo, CellInfo& info);
static void integrate_boundary_term (DoFInfo& dinfo, CellInfo& info);
static void integrate_face_term (DoFInfo& dinfo1, DoFInfo& dinfo2,
CellInfo& info1, CellInfo& info2);
...
}
The functions are implemented like this
template <int dim>
void ConservationLaw<dim>::integrate_cell_term (DoFInfo& dinfo,
CellInfo& info)
{
...
}
template <int dim>
void ConservationLaw<dim>::integrate_boundary_term (
DoFInfo& dinfo,
CellInfo& info)
{
...
}
template <int dim>
void ConservationLaw<dim>::integrate_face_term (
DoFInfo& dinfo1, DoFInfo& dinfo2,
CellInfo& info1, CellInfo& info2)
{
...
}
Finally, the assemble function is
template <int dim>
void ConservationLaw<dim>::assemble_system (Integrator<dim>& integrator)
{
std::cout << "start assemble\n";
MeshWorker::integration_loop<dim, dim>
(dof_handler.begin_active(), dof_handler.end(),
integrator.dof_info,
integrator.info_box,
boost::bind(&ConservationLaw<dim>::integrate_cell_term,
this, _1, _2),
boost::bind(&ConservationLaw<dim>::integrate_boundary_term,
this, _1, _2),
boost::bind(&ConservationLaw<dim>::integrate_face_term,
this, _1, _2, _3, _4),
integrator.assembler, true);
system_matrix.compress ();
}
But compiling the code gives me lot of boost errors:
$ make

What am I doing wrong ?
Thanks
