I have a std::map that I'd like to use the fast_pool_allocator with. But when I declare it, I get errors with rebind. typedef std::pair<IndexVariant, Hints> IndexMapType; typedef boost::fast_pool_allocator<IndexMapType> IndexPoolAllocator; typedef std::map<IndexVariant, Hints, std::less< IndexVariant >, IndexPoolAllocator> ValueHints; 1>C:\Program Files\Microsoft Visual Studio 8\VC\include\map(28) : error C2903: 'rebind' : symbol is neither a class template nor a function template 1> C:\Program Files\Microsoft Visual Studio 8\VC\include\xtree(26) : see reference to class template instantiation 'std::_Tmap_traits<_Kty,_Ty,_Pr,_Alloc,_Mfl>' being compiled 1> with 1> [ 1> _Kty=nw::IndexVariant, 1> _Ty=nw::Hints, 1> _Pr=std::less<nw::IndexVariant>, 1> _Alloc=nw::IndexPoolAllocator, 1> _Mfl=false 1> ] However, if I substitute: typedef std::allocator<IndexMapType> IndexPoolAllocator; it all compiles fine. I'd appreciate any help with my problem! :) Thanks, Scott
