Hello, All! I write example code for tuples::tuple::get use tuples::tie. If compile icl (Intel C++) v 7.1 or bcc32 (Borland) v 5.6.4 all ok, but if compile g++ (GCC) v 3.2.2 or cl (MSVC) v 13.00.9466 - i have eror. ;-c I need to use it in MSVC. Help me! ========tie.cpp======== #include <iostream> #include <boost/tuple/tuple.hpp> using std::cout; using std::endl; template <int num, typename T> void print(T t) { int i1 = 0, i2 = 0, i3 = 0; char c1 = '\0', c2 = '\0', c3 = '\0'; using boost::tuples::tie; tie(i1, i2, i3, c1, c2, c3).get<num>() = t; //Error in g++ & cl cout<<tie(i1, i2, i3, c1, c2, c3).get<num>()<<endl; //Error in g++ & cl } int main() { print<0>(0); print<1>(1); print<2>(2); print<3>('a'); print<4>('b'); print<5>('c'); return 0; } ========tie.cpp======== ========g++ command line====== c:\g++ -Iboost -otie tie.cpp
