Hello all, I'm trying to use ptr_set with my class Hierarchy.

Base is an abstract base class with a bunch of pure virtual functions.

I've some derived classes with those virtual functions defined in them.

I'm using this Base class hierarchy in another class (say Other).

So I've declared a member variable of Other as

ptr_set<Base> m_items ;

this works fine on linux with gcc-4.2 but with VS2005, I'm getting a compilation error, saying that It cannot instantiate base class as it is having pure virtual functions.

Am I doing some thing wrong here ?

Surya

The Base Class I'm talking about is derived from boost::noncopyable, with a protected Copy Constructor

I need more info than that to figure it out. -Thorsten
