After some googling and tinkering, I've found a solution, but I can't say I understand why it works.
Why you need the second declaration is beyond me. But it works.Code:// in a header file template <typename T> class A { static stl_container<T*>* container; }; //you need a second declaration outside the body of the class //in the header template <typename T> typename A<T>::stl_container<T*>* container;
Why is that so surprising? You have to do that even without templates.
How could it be otherwise? How does the compiler magically decide which .cpp module the definition of the static member should come from? The "static int x" is only a declaration -- you still need to define the variable in some specific .cpp module.Code:class A { public: static int x; }; int A::x; int main() { A::x = 0; return 0; }
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
