------- Comment #3 from _talyn_ at web dot de 2006-03-09 18:06 ------- Allocating the CVectorWrap variable dynamically removes the undefined reference to TTypeWrapper::~TTypeWrapper. I guess that's because it is virtual, and a dynamic instance of CVectorWrap will call CVectorWrap::~CVectorWrap via VMT. But this would mean that a copy of TTypeWrapper::~TTypeWrapper is somehow available, just not accessable outside instance.cc.
And there are the other link errors: get_type() and get<T>() are refereced in instance.cc. I guess they are inlined therein, and hence, referencing these functions from wrap_filter fails.
