That's right. Fixing warning C4251 for templates can cause multiply-defined symbol errors. Say you have some DLL with an exported class containing a std::vector<int> that you have explicitly instantiated and exported as shown above. Your C4251 warnings are fixed. Nice! But then you want to...
That may because std::vector<T>::push_back() creates a copy of the argument and stores it in the vector. If you want to store pointers to objects in your vector, try like this.prettyprint 复制 vector<Poly*> origPolys; Hope this could be help of you....
