[context] Use of nonexisting Dune::Std::to_true_v
I am getting compiler errors about a nonexisting Dune::Std::to_true_v
, for example
/home/sander/dune-book/code/dune-pdelab/dune/pdelab/assembler/finiteelementwrapper.hh: In member function ‘void Dune::PDELab::ReferenceGradientEvaluator<BasisWrapper, Basis_>::operator()(const X&, Container&) const’:
/home/sander/dune-book/code/dune-pdelab/dune/pdelab/assembler/finiteelementwrapper.hh:537:28: error: ‘to_true_v’ is not a member of ‘Dune::Std’
static_assert(Std::to_true_v<X> and not std::is_same_v<Range,int>,"basis does not support reference gradients");
Am I missing some dune-common
patches? Where are they?
