Are there any special compiler flags that I need to use to build a C++ project using boost with Visual Studio 2005? I am getting a C2220 compiler error that an object cannot be created: 1>------ Build started: Project: data_containers, Configuration: Debug Win32 ------ 1>Compiling... 1>Memory_Map.cpp 1>C:\Program Files\boost\boost_1_33_1\boost/format/group.hpp(124) : error C2220: warning treated as error - no 'object' file generated 1> C:\Program Files\boost\boost_1_33_1\boost/format/group.hpp(54) : see reference to class template instantiation 'boost::io::detail::group4' being compiled 1> with 1> [ 1> T1=std::ios_base &(__cdecl *)(std::ios_base &), 1> T2=std::_Smanipstd::ios_base::fmtflags, 1> T3=std::_Fillobj<char>, 1> T4=const boost::uint16_t & 1> ] 1> .\Memory_Map.cpp(341) : see reference to class template instantiation 'boost::io::detail::group1<T1>' being compiled 1> with 1> [ 1> T1=boost::io::detail::group4std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &> 1> ] 1>C:\Program Files\boost\boost_1_33_1\boost/format/group.hpp(124) : warning C4512: 'boost::io::detail::group4' : assignment operator could not be generated 1> with 1> [ 1> T1=std::ios_base &(__cdecl *)(std::ios_base &), 1> T2=std::_Smanipstd::ios_base::fmtflags, 1> T3=std::_Fillobj<char>, 1> T4=const boost::uint16_t & 1> ] 1>C:\Program Files\boost\boost_1_33_1\boost/format/group.hpp(58) : warning C4512: 'boost::io::detail::group1<T1>' : assignment operator could not be generated 1> with 1> [ 1> T1=boost::io::detail::group4std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &> 1> ] 1>C:\Program Files\boost\boost_1_33_1\boost/format/group.hpp(58) : warning C4512: 'boost::io::detail::group1<T1>' : assignment operator could not be generated 1> with 1> [ 1> T1=const boost::uint16_t & 1> ] 1> C:\Program Files\boost\boost_1_33_1\boost/format/feed_args.hpp(103) : see reference to class template instantiation 'boost::io::detail::group1<T1>' being compiled 1> with 1> [ 1> T1=const boost::uint16_t & 1> ] 1> C:\Program Files\boost\boost_1_33_1\boost/format/feed_args.hpp(150) : see reference to function template instantiation 'void boost::io::detail::put_last>(std::basic_ostream<_Elem,_Traits> &,const boost::io::detail::group1> &)' being compiled 1> with 1> [ 1> T1=std::ios_base &(__cdecl *)(std::ios_base &), 1> T2=std::_Smanipstd::ios_base::fmtflags, 1> T3=std::_Fillobj<char>, 1> T4=const boost::uint16_t &, 1> _Elem=char, 1> _Traits=std::char_traits<char> 1> ] 1> C:\Program Files\boost\boost_1_33_1\boost/format/feed_args.hpp(242) : see reference to function template instantiation 'void boost::io::detail::put(T,const boost::io::detail::format_item &,std::basic_string<_Elem,_Traits,_Ax> &,boost::io::basic_altstringbuf &,boost::io::detail::locale_t *)' being compiled 1> with 1> [ 1> Ch=char, 1> Tr=std::char_traits<char>, 1> Alloc=std::allocator<char>, 1> T=const boost::io::detail::group1std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &>> &, 1> _Elem=char, 1> _Traits=std::char_traits<char>, 1> _Ax=std::allocator<char> 1> ] 1> C:\Program Files\boost\boost_1_33_1\boost/format/feed_args.hpp(251) : see reference to function template instantiation 'void boost::io::detail::distribute(boost::basic_format<Ch> &,T)' being compiled 1> with 1> [ 1> Ch=char, 1> Tr=std::char_traits<char>, 1> Alloc=std::allocator<char>, 1> T=const boost::io::detail::group1std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &>> & 1> ] 1> C:\Program Files\boost\boost_1_33_1\boost/format/format_class.hpp(64) : see reference to function template instantiation 'boost::basic_format<Ch> &boost::io::detail::feed(boost::basic_format<Ch> &,const boost::io::detail::group1<T1>)' being compiled 1> with 1> [ 1> Ch=char, 1> Tr=std::char_traits<char>, 1> Alloc=std::allocator<char>, 1> T=boost::io::detail::group1std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &>>, 1> T1=boost::io::detail::group4std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &> 1> ] 1> .\Memory_Map.cpp(341) : see reference to function template instantiation 'boost::basic_format<Ch> &boost::basic_format<Ch>::operator %(const T &)' being compiled 1> with 1> [ 1> Ch=char, 1> T1=boost::io::detail::group4std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &>, 1> T=boost::io::detail::group1std::ios_base::fmtflags,std::_Fillobj<char>,const boost::uint16_t &>> 1> ]
