If I try to compile the very first example in multi index I get the following error: c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\boost\multi_index\detail\node_type.hpp(56) : error C2903: 'node_class' : symbol is neither a class template nor a function template I get this with 1.33 and 1.32. I've tried many different compiler options. Here is my latest command line: /Ox /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "NOMINMAX" /D "_AFXDLL" /D "_MBCS" /FD /EHsc /MD /GS /Fo"Release/" /Fd"Release/vc70.pdb" /W3 /nologo /c /Wp64 /Zi /TP I've dug around a bit and I can't make any sense of this problem. Has anyone else seen this? The exact code I'm compiling is: #include <boost/multi_index/key_extractors.hpp> #include <boost/multi_index_container.hpp> #include <string> struct employee { int id; std::string name; employee(int id,const std::string& name):id(id),name(name){} bool operator<(const employee& e)const{return id<e.id;} }; using namespace boost::multi_index; // define a multiply indexed set with indices by id and name typedef multi_index_container< employee, indexed_by< // sort by employee::operator< ordered_unique<identity<employee> >, // sort by less<string> on name ordered_non_unique<member<employee,std::string,&employee::name>

employee_set;

employee_set e; Thanks!
