Let me apologize in advance for my ignorance but I have not been able to update the following code successfully in order to migrate from Boost 1_29 to 1_33. Despite reading the boost::bind documentation a few times I am failing to make the necessary connection regarding the use of _1, _2 and handling the use of DeRef in the equal function below. // Unary dereference functor (a functor that returns the value of the specified // parameter, dereferenced via operator*) // (Note: This DeRef code is included in a separate header.) template < class Ptr, class T > struct DeRef : public std::unary_function< Ptr, T > { T & operator()( Ptr & ptr ) const { return *ptr;} }; // --- // Compare LocalStringMap (a custom map container with Tag/Value pair). // A TagValue is a class that contains a tag and a value (both strings) // A TagValuePtr is a custom, dereferencable smart pointer. inline bool LocalStringMap::operator==( const LocalStringMap &that ) const { // Must be same size if( this->size() != that.size() ) { return false;} return equal( this->_list.begin(), this->_list.end(), that._list.begin(), boost::compose_f_gx_hy( equal_to< TagValue >(), DeRef< const TagValuePtr, const TagValue

(), DeRef< const TagValuePtr, const TagValue >() ) ); }

Any assistance with this would be most helpful. I get the impression that I do not need to use the DeRef class the original author created given boost:bind's more capable traits identification. Here's what I have so far... return std::equal( this->_list.begin(), this->_list.end(), that._list.begin(), boost::bind<bool>( std::equal_to< TagValue >(), ???
