How to debug Boost tuple error "no operator found which takes a left-hand operand of type"

I have a boost::tuple list and I am using remove method to remove one of the entrie开发者_开发技巧s from that list. But I am getting the following error. How can I get rid of this?

c:\program files\microsoft visual studio 8\vc\include\algorithm(40) : error C2678: binary '==' : no operator found which takes a left-hand operand of type 'boost::tuples::tuple' (or there is no acceptable conversion)

You have to add an extra header for the comparisons

#include "boost/tuple/tuple_comparison.hpp"
