Thanks, inserting a few "public" keywords here and there makes this compile:
class Base {
public:
virtual int f(int x) = 0;
};
class Derived : public Base {
public:
int f(int x) {return 2*x;}
};
class BaseWrap : public Base, public boost::python::wrapper<Base>
{
public:
int f(int x)
{
return this->get_override("f")(x);
}
};
not sure if this is worth mentioning in the documentation, or is it
very obvious to everyone except newbies like myself... :)
