Compiling the folowing using is_iless as the predicate for a multi index
container results in errors. When is_less is used instead, it compiles
fine.

 

    typedef mi::multi_index_container<

        GTLayer,

        mi::indexed_by<

            mi::sequenced<>, // list-like index

            mi::ordered_unique<

                mi::tag<name>,

                mi::const_mem_fun<GTLayer, std::string,
&GTLayer::GetLayerName>,

                //std::greater<std::string>

                ::boost::algorithm::is_iless // names sorted

>

>

> layer_container;

 

The error messages are -

 

Error 4 error C2440: 'type cast' : cannot convert from
'std::basic_string<_Elem,_Traits,_Ax>' to 'unsigned char'
C:\Program Files\Microsoft Visual Studio 8\VC\include\xlocale 561

 

Error 3 error C2440: 'type cast' : cannot convert from
'unsigned char' to 'std::basic_string<_Elem,_Traits,_Ax>'
C:\Program Files\Microsoft Visual Studio 8\VC\include\xlocale 583

 

Is this an include problem? I have tried the following includes -

 

#include <boost/multi_index_container.hpp>

#include <boost/multi_index/mem_fun.hpp>

#include <boost/multi_index/ordered_index.hpp>

#include <boost/multi_index/sequenced_index.hpp>

#include <boost/algorithm/string/compare.hpp>

#include <boost/algorithm/string.hpp>

#include <boost/algorithm/string/predicate.hpp>

 

#include <map>

#include <string>

#include <cwchar>

#include <locale>

 

Thanks - Marcia
