Hey I just added my changes to a github branch ( https://github.com/gabpeters/dealii/tree/sparsity ) I changed the make_sparsity_pattern(dof_row,dor_col,sparsity) function and also changed the header in the dof_tools.h file and the signature in the dof_tools_sparsity.inst.in file. But still I get the following error, when I compile my code: undefined reference to `void dealii::DoFTools::make_sparsity_pattern<dealii::DoFHandler<3, 3>, dealii::DynamicSparsityPattern>(dealii::DoFHandler<3, 3> const&, dealii::DoFHandler<3, 3> const&, dealii::DynamicSparsityPattern&, dealii::ConstraintMatrix const&, bool)' Did I still forget to change any reference? Best Gabriel PS, you can ignore the make*s*_sparsity_pattern(...) function which I added to dof_tools_sparsity.cc > > Best, > Daniel > -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
