Re: [Boost-users] TR1 unordered_set: compilation failure with initialization

I want to pass in my own hash functor and comparator to an unordered_set initialization.   It fails compilation on g++ 4.2.1,  boost version 1.42. It’s not clear why, since a similar initialization of an STL  set container seems to work fine… see below for the code and compilation failure.  Any insight would be highly appreciated.

There isn't a matching constructor (I have no idea why). You need to give a minimum initial number of buckets, something like: m_unordered_set(10, foo_hash1(), foo_compare(is_gt)) Daniel
