Question

I\'m using clang (CXX=\'clang++ -std=c++11 -stdlib=libc++\') on Mac OS X, with boost 1.53.0.

I want to use uuid as keys in unordered_map, but getting the following e

Answer 1

Why bug in boost? You should specialize std::hash template for boost::uuid.

#include 

namespace std
{

template<>
struct hash
{
    size_t operator () (const boost::uuids::uuid& uid)
    {
        return boost::hash()(uid);
    }
};

}

or, simply create unordered_map with boost::hash par

std::unordered_map>

or provide hash functor that satisfies requirements of std::hash (thanks to Praetorian).
