Accessing base member data error when derived class is templated

Question

I have the following problem with the curiously recurring template, with a problem when I try to access the data member of CRTP base class.

Answer 1

It doesn't really have to do with CRTP, but rather with the fact that for dependent-base-accessing derived code, you need to qualify things.

Changing the line to

std::cout<<this->protectedData<<std::endl;

solved it.
