- Windows support is currently highly experimental. For installing on Windows, please refer to additional - information on the deal.II Wiki and have a look at the bug - tracker! Please note that the Microsoft Visual C++ compiler, that is widely used on Microsoft Windows, is not supported. If you need a native Windows target, use the MinGW compiler instead. diff --git a/deal.II/include/deal.II/base/geometry_info.h b/deal.II/include/deal.II/base/geometry_info.h index ced3b187de..ea6d4b11f1 100644 --- a/deal.II/include/deal.II/base/geometry_info.h +++ b/deal.II/include/deal.II/base/geometry_info.h @@ -1457,7 +1457,13 @@ struct GeometryInfo /** * Number of vertices of a cell. */ +#ifdef DEAL_II_USE_CXX11 + // Workaround for some versions of gcc-4.8.1 (notably on Cygwin and Mac) + // that incorrectly fail to deduce the second version as a constexpr + static constexpr unsigned int vertices_per_cell = 1 << dim; +#else static const unsigned int vertices_per_cell = 1 << dim; +#endif /** * Number of vertices on each diff --git a/deal.II/source/base/geometry_info.cc b/deal.II/source/base/geometry_info.cc index 6569451117..5765bb6826 100644 --- a/deal.II/source/base/geometry_info.cc +++ b/deal.II/source/base/geometry_info.cc @@ -31,7 +31,13 @@ GeometryInfo<0>::n_children(const RefinementCase<0> &) template const unsigned int GeometryInfo::max_children_per_cell; template const unsigned int GeometryInfo::faces_per_cell; template const unsigned int GeometryInfo::max_children_per_face; -template const unsigned int GeometryInfo::vertices_per_cell; +#ifdef DEAL_II_USE_CXX11 + // Workaround for some versions of gcc-4.8.1 (notably on Cygwin and Mac) + // that incorrectly fail to deduce the second version as a constexpr + template constexpr unsigned int GeometryInfo::vertices_per_cell; +#else + template const unsigned int GeometryInfo::vertices_per_cell; +#endif template const unsigned int GeometryInfo::vertices_per_face; template const unsigned int GeometryInfo::lines_per_face; template const unsigned int GeometryInfo::quads_per_face; -- 2.39.5
