Hello all,I'm a newbie to multi-index. I ran into a strange problem with VS2008. When using BOOST_AUTO with multi-index I'm getting compilation errors (C2248) . Please see the following code. *<snip>* * * #include <iostream> #include <string> using namespace std ; #include <boost/multi_index_container.hpp> #include <boost/multi_index/mem_fun.hpp> #include <boost/multi_index/ordered_index.hpp> #include <boost/multi_index/identity.hpp> #include <boost/multi_index/member.hpp> #include <boost/foreach.hpp> #include <boost/typeof/typeof.hpp> using namespace boost ; using namespace boost::multi_index ; class Test { friend bool operator< (const Test& p_lhs, const Test& p_rhs) { return p_lhs._i < p_rhs._i ; } friend ostream& operator << (ostream& os, const Test& p_test) { os << "Integer: " << p_test._i << "\tString: " << p_test._s ; return os ; } private: int _i ; string _s ; public: Test (int i, string s): _i(i), _s(s) { } string getString (void) const { return _s ; } } ; struct byNumber { } ; struct byString { } ; int main (void) { typedef multi_index_container <Test, indexed_by < ordered_unique<tag<byNumber>, identity <Test> > , ordered_non_unique < tag<byString>, BOOST_MULTI_INDEX_CONST_MEM_FUN(Test, string, getString) >

Container ;

typedef Container::index<byNumber>::type TestByNumber ; typedef Container::index<byString>::type TestByString ; Container c ; c.insert (Test(5, "Surya")) ; c.insert (Test(15, "Kiran")) ; //TestByNumber& tests = c.get<byNumber>() ; BOOST_AUTO(tests, c.get<byNumber>()) ; BOOST_FOREACH (Test t, tests) cout << t << endl ; return 0 ; } *</snip>* * * Compilation for this case fails with C2248. If I replace the BOOST_AUTO with the previous line's statement, compilation goes well. This happens with VS2008 only. with VS2005, there's no issue with BOOST_AUTO. Am I missing something here? Thanks, Surya
