Tutorial 40 , error: use of deleted function

[ztdep...@gmail.com]

when i compile the tutorial 40, i met the following error. It semms that the function has been deleted. 

 error: use of deleted function ‘dealii::parallel::distributed::Triangulation<dim, spacedim>::Triangulation(const MPI_Comm&, typename dealii::Triangulation<dim, spacedim>::MeshSmoothing, dealii::parallel::distributed::Triangulation<dim, spacedim>::Settings) [with int dim = 2; int spacedim = 2; MPI_Comm = int; typename dealii::Triangulation<dim, spacedim>::MeshSmoothing = dealii::Triangulation<2, 2>::MeshSmoothing]’

Hi,

the copy constructor for Triangulation is indeed deleted. If you do need a copy, you may want to use copy_triangulation(), that is also implemented for p::d::T.

Best,

Marco

You would get this compile-time error if you haven't configured deal.II with `DEAL_II_WITH_MPI=ON`.

Best,

Daniel

Ah, I hadn’t noticed you were compiling a tutorial program. My apologies.
