system : ubuntu20 compiler : x86_64-linux-gnu g++ compiler version : 9.4.0 build error : undefined reference to 'Log4Qt::AppenderAttachable::~AppenderAttachable()'

Hallo, I can not reproduce this on Ubuntu 20.04 and gcc 9.4. It should not be necessary to define a empty destruction in MainThreadAppender. Any more details why this fails for you?

This problem will occur when I inherit the MainThreadAppender Class to implement a custom Adapter Class.
