[boost] [multi_index]: Migration of code to VS12 does not compile anymore

Hello, I'm porting some code fromVS10 to the VS12 compiler on windows. I have a problem compiling code like the following: //Test.cpp #include #include #include #include template<typename T> class test { public: typedef typename boost::multi_index_container < T*, boost::multi_index::indexed_by < boost::multi_index::random_access<>, boost::multi_index::hashed_non_unique < boost::multi_index::identity > > > container_t; typedef typename container_t::nth_index<0>::type sequence_index_t; }; This does not compile and gives the following error message: 1> Test.cpp 1>D:\test\Test.cpp(18): error C2059: syntax error : '<' 1> D:\test\Test.cpp(19) : see reference to class template instantiation 'test<T>' being compiled 1>D:\test\Test.cpp(18): error C2238: unexpected token(s) preceding ';' I'm unable to find the reason for this error. Is it a compiler error, or is something wrong with my declaration? Regards, Johannes
