color compilation

[tomsib2001]

When trying to compile color.ml using the proposed command with Ocaml 4.02.1 or Ocaml 4.02.3

make color.opt

I get the error

ocamlopt.opt -o color.opt -g -annot  -I +ocamlgraph unix.cmxa graphics.cmxa graph.cmxa combine.cmxa color.ml
File "color.ml", line 25, characters 5-10:
Error: Unbound module Graph
make: *** [color.opt] Erreur 2

But the issue here is not my installation of ocamlgraph, as if I create a file toto.ml with just

open Graph

and compile it using

ocamlbuid -package ocamlgraph toto.native

the log says

### Starting build.

This is indeed a compilation issue: our Makefile entry for color.opt is
assuming OCamlGraph has been installed in subdirectory ocamlgraph/ of
OCaml's standard library and not via ocamlfind (which must be your case).

The correct compilation command for color.opt should then rather be

ocamlfind ocamlopt -package ocamlgraph -package graphics -package unix
-linkpkg combine.cmxa color.ml -o color.opt

Thanks for reporting this issue.
