[Dune] [Dune-Commit] dune-grid r7723 - trunk/dune/grid/io/file/vtk+

[Adrian Ngo]

Hi all,

I haven't done anything special to get a build error.
I just checked out all the latest trunk revisions necessary to build 
dune-pdelab-howto and I got this:

example01a_Q1.hh:40: error: no matching function for call to 
'Dune::VTKWriter<Dune::GridView<Dune::DefaultLeafGridViewTraits<const 
Dune::YaspGrid<2>, (Dune::PartitionIteratorType)4u> >

Dune::YaspGrid<2>, (Dune::PartitionIteratorType)4u> >, 
Dune::PDELab::Q1LocalFiniteElementMap<double, double, 2>, 
Dune::PDELab::NoConstraints, Dune::PDELab::ISTLVectorBackend<1>, 
Dune::PDELab::GridFunctionGeneralMapper>,

Bye,
Adrian
