Hi,,
In the example from the doc
typedef mpl::vector< copy_constructible<_a>, copy_constructible<_b>, copy_constructible<_c>, constructible<_a(const _b&, const _c&)> > construct;
std::vector<double> vec; int i = 10; double d = 2.5; tuple<construct, _a&, _b, _c> t(vec, i, d); any<construct, _a> v(get<1>(t), get<2>(t));

How should the code be changed to allow compilation?
It compiles OK when the -std=gnu++11 option is removed. However, it's still producing warnings like: ../../../boost/type_erasure/detail/adapt_to_vtable.hpp: In static member function 'static R boost::type_erasure::detail::vtable_adapter<PrimitiveConcept, R()>::value()': ../../../boost/type_erasure/detail/adapt_to_vtable.hpp:236:11: warning: typedef 'traits' locally defined but not used [-Wunused-local-typedefs] > traits; ^ In file included from botet_construct.cpp:6:0: ../../../boost/type_erasure/any_cast.hpp: In function 'T boost::type_erasure::any_cast(const boost::type_erasure::any<Concept, Tag>&)': ../../../boost/type_erasure/any_cast.hpp:132:13: warning: typedef 'tag_type' locally defined but not used [-Wunused-local-typedefs] >::type tag_type; ^ This is with compiler: ftp://gcc.gnu.org/pub/gcc/snapshots/4.8-20120624/gcc-4.8-20120624.tar.bz2 -regards, Larry
