Hi, I have a simple collection template that uses boost::shared_ptr and std::list. I have used this with Borland Builder 5/6 for sometime now with no problems. I am moving some code that uses the template to GCC(3.2.3) and have found that this is giving me some depreciation warnings. A snip of my template(coll.h): template <class T> class Collection { private: list < shared_ptr<T> > items; list < shared_ptr<T> >::iterator iter; ... }; And the errors: coll.h:106: warning: `typename std::list<boost::shared_ptr<T>, std::allocator<boost::shared_ptr<T> > >::iterator' is implicitly a typename coll.h:106: warning: implicit typename is deprecated, please see the documentation for details coll.h:107: warning: `typename std::list<boost::shared_ptr<T>, std::allocator<boost::shared_ptr<T> > >::iterator' is implicitly a typename coll.h:107: warning: implicit typename is deprecated, please see the documentation for details Is there a different method that I need to use for GCC? Thanks, Chris
