Hello I have tried to run this example with deal.II 9.1.0 and this problem still persists. With deal.II 9.0.0/9.0.1 the example fails to compile because it requires affine_constraints.h, which is not yet introduced:
/home/hbui/workspace2/deal.II/time_dependent_navier_stokes/time_dependent_navier_stokes.cc:9:10: fatal error: deal.II/lac/affine_constraints.h: No such file or directory #include <deal.II/lac/affine_constraints.h> Therefore I think the problem might lie somewhere between 9.0.1 and 9.1.0. However, I did not see any other tags except 9.1.0-rc1,2,3.
