Your post is very difficult to read with all of those "%%%%%%" lines.
Please post your code again and use code tags. Click the "Format:" button that looks like "<>", and paste your code between the generated tags. This will allow the indentation of your code to remain as well as line numbers that help us with comments.
You say that the destructors are defined in the header file, but you only show us the declarations. There is no destructor definition shown in your code. Despite your assurances to the contrary, it appears you never define your destructors, and that is why the linker error is encountered.
Please post the entire header files so we can see what you actually have and do not have defined. If this is too much code, strip out everything unnecessary, but leave enough that can be compiled and will still result in the problem. (Try to compile it to make sure)
Also, I don't think it's causing the problem, but since Liztiter_ATTLC is used as a base class, its destructor should be declared virtual.
