hey Gili
this is what i know from my limited exp with computing:

mainly - unknown reference in this case would relate to not being able to see
the _source_ code (ie method definition) of the method. Thus in your case i
don't think it is the case of inlining at all.
So if you include headers  - those would include declaration of method - the
definition of those are in cpp - and perhaps your make file or linker do not
find the source for definitions of the methods in the files that you specified
as your source files and lib files.

- just a general thing on inlining - it is only a suggestion to compiler - since
inlining replaces method name with actual code - the compiler must know the
exact instance of class when compiling (ie at static time) - so if you have
something like pointer to method - inlining definitely won'r work.
