This seems reasonable enough no? :) > > Gili 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.
