RE: [boost] pool_alloc with Pair Associative Container?

Your declaration looks correct to me.

hash_map is part of SGI's STL/STLPort. It will support Standard C++
Allocators IF the underlying compiler is capable of it (requires member
template support). Otherwise, it has a nice fallback mechanism that uses its
own form of STLPort Allocator.

pool_alloc provides a Standard C++ Allocator; it does not support the
STLPort Allocator interface. So, it sounds like you're using a compiler that
is not capable of supporting Standard C++ Allocators properly.

Subject: [boost] pool_alloc with Pair Associative Container?

Can someone give me an example of how to use the boost pool_alloc
allocator interface with a Pair Associative Container, like hash_map?
I tried doing something like
typedef hash_map<long long,double,longLongHasher,boost::pool_allocator<
pair<const long long,double> > > tLongLongToDoubleHashMap;

,,,but I get errors when I try to compile code that actually uses
tLongLongToDoubleHashMap.

Thanks!
Thomas
