Hi ! Today my company switched over to MSVC 1310 ( Visual Studio .NET 2003 ) We make heavy use of some boost libraries. And now we have a real showstopper, boost::format does nto compile anymore without errors. Are there any fixes for that ? we use boost_1_30_0 built using the VC7 toolset ( from MSVC 7.1 ) Here is the code passage that causes errors ( but many others do the same ) // Generate a unique dummy name. boost::format uniqueName("Unknown%1%"); int idNumber = sNames.size() + sIdCounter; // Just an integer. uniqueName % idNumber; Here are the compiler errors: d:\Sdk\boost\boost\format\feed_args.hpp(79) : error C2065: 'disambiguater' : undeclared identifier d:\Sdk\boost\boost\format\feed_args.hpp(140) : see reference to function template instantiation 'void boost::io::detail::`anonymous-namespace'::put_head<char,std::char_traits<char>,T>(std::basic_ostream<_Elem,_Traits> &,const T &)' being compiled with [ T=int, _Elem=char, _Traits=std::char_traits<char> ] d:\Sdk\boost\boost\format\feed_args.hpp(237) : see reference to function template instantiation 'void boost::io::detail::`anonymous-namespace'::put<Ch,Tr,T>(T,const boost::io::detail::format_item<Ch,Tr> &,std::basic_string<_Elem,_Traits,_Ax> &,std::basic_ostringstream<_Elem,_Traits,_Alloc> &)' being compiled with [ Ch=boost::basic_format<char>::CharT, Tr=boost::basic_format<char>::Traits, T=const int &, _Elem=char, _Traits=std::char_traits<char>, _Ax=std::allocator<char>, _Alloc=std::allocator<char> ] d:\Sdk\boost\boost\format\feed_args.hpp(246) : see reference to function template instantiation 'void boost::io::detail::distribute<Ch,Tr,T>(boost::basic_format<Ch> &,T)' being compiled with [ Ch=boost::basic_format<char>::CharT, Tr=boost::basic_format<char>::Traits, T=const int & ] d:\Sdk\boost\boost\format\format_class.hpp(63) : see reference to function template instantiation 'boost::basic_format<Ch> &boost::io::detail::feed<boost::basic_format<Ch>::CharT,boost::basic_format<Ch>::Traits,const T&>(boost::basic_format<Ch> &,const int)' being compiled with [ Ch=char, T=int ] d:\Work\FakedReality\Source\Core\Engine\Identifier.cpp(87) : see reference to function template instantiation 'boost::basic_format<Ch> &boost::basic_format<Ch>::operator %<int>(const T &)' being compiled with [ Ch=char, T=int ] d:\Sdk\boost\boost\format\feed_args.hpp(79) : error C2275: 'Ch' : illegal use of this type as an expression d:\Sdk\boost\boost\format\feed_args.hpp(140) : see declaration of 'Ch' d:\Sdk\boost\boost\format\feed_args.hpp(79) : error C2039: 'put_head' : is not a member of 'operator``global namespace''' d:\Sdk\boost\boost\format\feed_args.hpp(79) : error C2780: 'void boost::io::detail::`anonymous-namespace'::put_head(std::basic_ostream<Ch,Tr> &,const T &)' : expects 2 arguments -
