Hi List, I have the following problem. I have three files, each consisting of one line: a.ml: type t = float b.ml: type t = A.t c.ml: include B Now I want to put these modules into a pack, but I only want to export A and C, so I write a file project.mli: module A : sig type t end module C : sig type t = A.t end As I want to use ocamlbuild, I also create a file project.mlpack: A C Now, the command "ocamlbuild project.cmo" works fine, but I can't build a library from that: ocamlbuild project.cma Circular dependencies: "project.cmo" already seen in [ "b.cmo"; "project.cmo" ] There clearly aren't any circular dependencies, are there? Am I missing something? The problem goes away if I export B instead of C. So the troublemaker seems to be the include directive. I almost forgot: I am using ocaml 3.10.2 from godi.
