Hi,
I am trying to migrate my project to 1.35. The following used to compile and work with 1.34.1: bmx::multi_index_container<wstring, bmx::indexed_by<bmx::ordered_unique<bmx::identity<wstring> >, bmx::random_access<> >, boost::fast_pool_allocator<wstring> >
But refuses to compile with 1.35 (I use Intel compiler 10.1 with MSVC7.1 STL). Something to do with allocator rebind. I am including some of the compiler output below.
Can someone please suggest a resolution (hopefully keeping the pool allocator intact)?
Hi Amit, Steven is right on spot: boost::fast_pool_allocator is not correctly specialized for void, as it should. I'll file a bug report about this. In the meantime, you can simply replace fast_pool_allocator with the following fixed_fast_pool_allocator class: template< typename T, typename UserAllocator=boost::default_user_allocator_new_delete
class fixed_fast_pool_allocator: public boost::fast_pool_allocator<T,UserAllocator> { typedef boost::fast_pool_allocator<T,UserAllocator> super; public: template<typename U> struct rebind {typedef fixed_fast_pool_allocator<U, UserAllocator> other;}; fixed_fast_pool_allocator(){} fixed_fast_pool_allocator(const fixed_fast_pool_allocator&x):super(x){} template<typename U> fixed_fast_pool_allocator( const fixed_fast_pool_allocator<U,UserAllocator>& x):super(x){} }; template<typename UserAllocator> class fixed_fast_pool_allocator<void,UserAllocator> { public: typedef void* pointer; typedef const void* const_pointer; typedef void value_type; template<typename U> struct rebind {typedef fixed_fast_pool_allocator<U, UserAllocator> other;}; }; Does this solve your problem? Please report back. Thanks for using Boost.MultiIndex, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
