I see that Boost.Container has already defined in namespace boost::container and in file boost/container/scoped_allocator.hpp the following
struct allocator_arg_t { }; constexpr allocator_arg_t allocator_arg = allocator_arg_t();
template <class T, class Alloc> struct uses_allocator;
There is no constexpr in Boost.Container code. Current trunk code includes an experimental implementation of scoped_allocator, for C++03 and C++11 compilers.
I would like to shared these to all the Boost libraries. I don't think it is a good idea to make Boost.Thread depend on Boost.Container just for this. Could these declarations be included in a specific file? These declaration are included in <memory> in the C++11. What would be the best library to contain these declarations?
I don't think Boost.thread should depend on Boost.Container, that's why I've added those classes to boost::container namespace, avoiding any boost:: namespace pollution. The idea is also to define them as std:: typedefs so that a user with a C++11 conforming standard library does not need to add boost::container::xxx overloads. And user C++03 code using boost::xxx types is standard conforming when compiled with C++11 compilers. Have you a plan to add these definitions at the boost level? BTW,
I'm getting ../../../boost/container/allocator_traits.hpp:170:105: error: type name requires a specifier or qualifier template <typename T> using rebind_alloc = boost::intrusive::detail::type_rebinder<Alloc, T>::type; when compiling with clang 3.0 C++11 Adding typename in #if !defined(BOOST_NO_TEMPLATE_ALIASES) //C++11 template <typename T> using rebind_alloc = typename boost::intrusive::detail::type_rebinder<Alloc, T>::type; Solve the issue. I have checked it with clang 3.0 (c++11) and gcc-4.7.0 (c++11). Could you try to fix this? Thanks, Vicente
