Re: Why do I get: cannot declare variable ? sc¹ to be of abstract type...


Hi Dave,

> I would think that I1::a() is not virtual because it is defined in the super
class C1.  What is going on here?

I1::a was defined in super class C1 for the C1 half of the multiple
inheritance (via C2::C1::I2::defined a), but the I2 half's (via
C2::I2::I1::pure virtual a) a has not been concretely defined anywhere up
that inheritance chain.

HTH,
