Thanks again! that one was very logical ... silly me!
To review, now it looks like this:
std::map<types::global_dof_index, PetscScalar> bval;
ZeroFunction<dim,PetscScalar> homogeneous_dirichlet_bc;
const typename FunctionMap<dim,PetscScalar>::type
dirichlet_boundary_functions
= { { types::boundary_id(0), &homogeneous_dirichlet_bc } };
VectorTools::interpolate_boundary_values (mapping_collection,
dof_handler,
dirichlet_boundary_functions,
bval);
and gives the following error (no candidates this time):
path/petsc_eigs/pFEM.cc:370: error: undefined reference to 'void
dealii::VectorTools::interpolate_boundary_values<2, 2, std::complex<double>
>(dealii::hp::MappingCollection<2, 2> const&, dealii::hp::DoFHandler<2, 2>
const&, std::map<unsigned int, dealii::Function<2, std::complex<double> >
const*, std::less<unsigned int>, std::allocator<std::pair<unsigned int
const, dealii::Function<2, std::complex<double> > const*> > > const&,
std::map<unsigned int, std::complex<double>, std::less<unsigned int>,
std::allocator<std::pair<unsigned int const, std::complex<double> > > >&,
dealii::ComponentMask const&)'
collect2: error: ld returned 1 exit status

Any comments? thanks in advance,
Juan Araújo
