I have not yet looked too much into the source, but if the batteries_core.ml is one of them to be referenced anyway, I'm afraid all modules (not just parents/siblings) will be linked. Try to compile the following source into executable: ---- open Batteries.Data.Persistent.List let _ = iter ---- You will end up with being asked for numerous unrelated modules during the linking phrase, or you can use the recommended "ocamlfind batteries/ocamlc" shortcut. Either way, an executable of +50 times bigger in size (i.e. +1M for the 2 lines) than using the standard List will be produced. -- Zheng > On Tue, 2008-11-18 at 11:21 +0100, Zheng Li wrote: >>> Your biggest problem is using dot ('.') instead of underscore ('_'). >>> Using a dot means that the System namespace cannot be extended by >>> external packages.
