Hi, I can't figure out why the following code generates a compile error with gcc 3.4: Hi,
shouldn't it be:
template<typename E,typename T> typename boost::tuples::element<typename boost::mpl::at_c<E,0>::type::value,T>::type foo(E e,T t) { return t.get<0>(); }
Regards, Vinzenz Nevermind this wasn't the problem. Here's a working one ;)
#include <boost/mpl/vector_c.hpp> #include <boost/mpl/at.hpp> #include <boost/tuple/tuple.hpp> template<typename E,typename T> typename boost::tuples::element< boost::mpl::at_c<E,0>::type::value , T >::type foo(E e, T t) { return boost::get<0>(t); } int main() { typedef boost::mpl::vector_c<int,0,1> elements; boost::tuple<int> t(1); foo(elements(),t); }
