Building an OCaml package

Building an OCaml package

The details relating to OCaml package construction are provided in the the OCaml System Release 4.00 documentation and users manual. Here's how I go about it. The key to building an OCaml package is to first compile the package modules with the -for-pack flag and then combine the compiled modules with the -pack flag. The procedure can be nicely wrapped up in an OMake macro, presented in this OMakefile schematic. 

make_package(P, libname, S) =
  for_pack (P, f) = 
    OCAMLFLAGS = -for-pack $(P)
    $(f).cmx $(f)$(EXT_OBJ):
    $(f).cmo:
    $(f).cmi:
  foreach (f, $(S))
    for_pack ($(P), $(f))
  section
    .DEFAULT: $(OCamlPackage $(P), $(S))
  .DEFAULT: $(OCamlLibraryInstall _,$(BIN_DIR), $(libname), $(P))

S=$(rootname $(file $(basename $(glob *.ml)) ))

make_package(Foo, foo, $(S))
