Hi I'm getting a compile error in Visual Studio 8 with boost 1.33.1 It looks like the boost namespace is not being honored, as ATL::CString has no business here. I don't know how to get around it, other than rewriting this function: boost::split( splitVec, csText, boost::is_any_of(",") ); The boost::is_any_of call triggers the error. 1>w:\boost\boost_1_33_1\boost\range\const_iterator.hpp(36) : error C2039: 'const_iterator' : is not a member of 'ATL::CStringT<BaseType,StringTraits>' 1> with 1> [ 1> BaseType=char, 1> StringTraits=StrTraitMFC_DLL<char> 1> ] 1> w:\boost\boost_1_33_1\boost\range\result_iterator.hpp(35) : see reference to class template instantiation 'boost::range_const_iterator<C>' being compiled 1> with 1> [ 1> C=CString 1> ] 1> w:\boost\boost_1_33_1\boost\algorithm\string\iter_find.hpp(144) : see reference to class template instantiation 'boost::range_result_iterator<C>' being compiled 1> with 1> [ 1> C=CString 1> ] 1> w:\boost\boost_1_33_1\boost\algorithm\string\split.hpp(148) : see reference to function template instantiation 'SequenceSequenceT &boost::algorithm::iter_split<SequenceSequenceT,RangeT,boost::algorithm::detail::token_finderF<PredicateT>>(SequenceSequenceT &,RangeT &,FinderT)' being compiled 1> with 1> [ 1> SequenceSequenceT=std::vector<std::string>, 1> RangeT=CString, 1> PredicateT=boost::algorithm::detail::is_any_ofF<char>, 1> FinderT=boost::algorithm::detail::token_finderF<boost::algorithm::detail::is_any_ofF<char>> 1> ] 1> c:\codejock apps\qp charts\charts\exportlisttoasciidlg.cpp(98) : see reference to function template instantiation 'SequenceSequenceT &boost::algorithm::split<std::vector<_Ty>,CString,boost::algorithm::detail::is_any_ofF<CharT>>(SequenceSequenceT &,RangeT &,PredicateT,boost::algorithm::token_compress_mode_type)' being compiled 1> with 1> [ 1> SequenceSequenceT=std::vector<std::string>, 1> _Ty=std::string, 1> CharT=char, 1> RangeT=CString, 1> PredicateT=boost::algorithm::detail::is_any_ofF<char> 1> ] Any help is certainly appreciated.
