Hi, I need help to get started with boost, Im trying about some time to get a little project mine converted to use boost libs. My current project uses raw pointers and std::map. But I want to use shared_ptr and multi_index_container. I cant find help anywhere to my problems with this code, I hope I can get some here. Project Outline: - Strict OO design. - Filesystem emulation (a simple fake filesystem...) - I have one Filesytem interface with one implementation. - I have one Entry interface with three implementations. - Directory is a Entry. - File is a Entry. - Empty is a Entry. See the sample here: http://rafb.net/paste/results/hfHOx934.html , I have done this little sample to start understunding multi_index_container with classes using methods (mem_fun) as "selectors?". What is wrong with it? Please, I really need help to start with boost. But I doesnt want to let use best practices like good design and patterns. Thanks -- Animal Frontline Liberation
