Hi, I simplified my problem to make sure it was not because of my class or something like that, this is the exact content(related to boost::multi_index) in the header file, example.h #include <boost/multi_index_container.hpp> #include <boost/multi_index/mem_fun.hpp> #include <boost/multi_index/hashed_index.hpp> using namespace boost::multi_index; using boost::multi_index::multi_index_container; using boost::multi_index::hashed_unique; using boost::multi_index::indexed_by; typedef multi_index_container< int, indexed_by< hashed_unique<identity<int> >
int_multiset;
and then below it in the header file I have my class written, as follows, class MgrABC : public MainManager { public: int_multiset sample1; <already existing code> . . . protected: virtual void _handler(); <already existing code> . . . }; In the corresponding cpp file example.cpp void MgrABC::_handler() { <already existing code 4 or 5 lines of variable declarations> . . . this->sample1.insert(1); <already existing code> . . . } This simple code is not compiling with this same error, Exact build output, Compiling... example.cpp c:\sample\common\lib\boost\boost\detail\allocator_utilities.hpp(153) : error C2061: syntax error : identifier 'p' c:\sample\common\lib\boost\boost\multi_index\detail\index_base.hpp(105) : see reference to function template instantiation 'void boost::detail::allocator::construct<int>(void *,const Type &)' being compiled with [ Type=int ] c:\sample\common\lib\boost\boost\multi_index\detail\index_base.hpp(102) : while compiling class template member function 'boost::multi_index::detail::hashed_index_node<Super,Category> *boost::multi_index::detail::index_base<Value,IndexSpecifierList,Allocator>::insert_(const int &,boost::multi_index::detail::hashed_index_node<Super,Category> *&,boost::multi_index::detail::lvalue_tag)' with [ Super=boost::multi_index::detail::index_node_base<int, std::allocator<Vs32>>, Category=boost::multi_index::detail::hashed_unique_tag, Value=int, IndexSpecifierList=boost::multi_index::indexed_by<boost: :multi_index::hashed_unique<boost::multi_index::identity<int>>>, Allocator=std::allocator<Vs32> ] c:\sample\common\lib\boost\boost\multi_index\hashed_index.hpp(93) : see reference to class template instantiation 'boost::multi_index::detail:: index_base<Value,IndexSpecifierList,Allocator>' being compiled with [ Value=int, IndexSpecifierList=boost::multi_index::indexed_by<boost: :multi_index::hashed_unique<boost::multi_index::identity<int>>>, Allocator=std::allocator<Vs32> ] c:\sample\common\lib\boost\boost\multi_index_container.hpp(100) : see reference to class template instantiation 'boost::multi_index::detail:: hashed_index<KeyFromValue,Hash,Pred,SuperMeta,TagList,Category>' being compiled with [ KeyFromValue=boost::multi_index::identity<int>, Hash=boost::hash<int>, Pred=std::equal_to<int>, SuperMeta=boost::multi_index::detail::nth_layer<1,int,boost: :multi_index::indexed_by<boost::multi_index::hashed_ unique<boost::multi_index::identity<int>>>,std::allocator<Vs32>>, TagList=boost::mpl::vector0<boost::mpl::na>, Category=boost::multi_index::detail::hashed_unique_tag ] c:\sample\example.h(102) : see reference to class template instantiation 'boost::multi_index::multi_index_container<Value,IndexSpecifierList>' being compiled with [ Value=int, IndexSpecifierList=boost::multi_index::indexed_by<boost: :multi_index::hashed_unique<boost::multi_index::identity<int>>> ] Build log was saved at "file://c:\sample\build\bin\ sample\win\Debug\obj\BuildLog.htm" Sample - 1 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== Thanks, Ram
