Re: [Boost-users] [bcp] [shared_ptr] Extracting subset of boostforshared_ptr - 3.2MB?

Unfortunately bcp isn't smart enough to not look into optional dependencies that are guarded by #ifdef. In this particular case it follows the dependency to detail/quick_allocator.hpp, which in turn brings in the type_traits and mpl libraries. But quick_allocator.hpp is only used if you #define BOOST_SP_USE_QUICK_ALLOCATOR.

Peter, this comes up so often, I wonder is it worth while "hiding" that optional dependency behind a #define, as in: #define BOOST_SP_QA #ifdef BOOST_SP_USE_QUICK_ALLOCATOR #include BOOST_SP_QA #endif Of course I have no data on how often that dependency is actually needed (or not). John.
