This is should not be an issue, it is designed that way: because VCAI calls to CCallback relies on VMT, VCAI doesn’t need to be linked with CCallback. Function calls are resolved in runtime, not build time.
VCAI does not create objects of CCallback, so linker should not need its VMT. It is enough if VCMI receives a ready object with already set VMT.

Have you tried clean rebuild? It often helps me with such errors.

Clean build of just VCAI did not help. Will do full rebuild tomorrow.

Full clean rebuild did not help. still same error.

Huh… Hard to say.
What is taht ZN9CCallbackD1Ev functoin? Could you try demangling that name? CCallback destructor…?
Can you try checking which revision broke this?

yes.

this will take … some time.

What if you added to the CCallback.h / CCallback.cpp trivial destructor virtual ~CCallback?
Then it won’t be compile generated and won’t be part of VCAI.cpp compile unit.

It works! Thanks.

cannot compile still :-

Compilation is OK for me. This looks more like incorrectly installed boost.
