I have faced that problems many times as well.

If you use inline methods, then you have to write them in the header file (of
course) AND (if implemented not directly in the class def) it is good to
declare them RIGHT behind the class definition - not anywhere else. This seems
to be a bug of gcc.

Also some func in an object don't seem to be linked if related header files are
NOT DIRECTLY included (#include) from the code that uses these functions

Thus play a bit with header files, postition of inline methods (in .h file if
any) and (perhaps) the order of linking the objects / libs.

Hope this helps!
