c++ - abstract class as virtual base class
struct A { virtual void f() { } }; struct B : public A { virtual void g() = 0; }; struct D : public virtual B { virtual void g() { } }; struct E : public virtual B, public D { }; int main() { E e; // Error: cannot create instance of abstract class 'E' return 0; } It works if I change the definition of E to: struct E : public D, public virtual B { }; which makes it a low-priority bug. bye, Christof -- http://cmeerw.org JID: cmeerw jabber.at mailto cmeerw at web.de ...and what have you contributed to the Net?
