At a guess, and not having looked at the code or logs, I would say it’s either a virtual destructor defined in a header file (that can cause problems with the vtable not being generated by any compilation unit) or it has been built with -fvisibility=hidden and the class is not marked with visibility(“default”) and so members are not exported from the library
