Target function to build OCaml Library with foreign sources/objects?

[cspiel]

I would like to build a native OCaml library that consists of several OCaml sources and a C-source (a.k.a. "foreign source"). Obviously, OCamlLibrary cannot generate an appropriate target as its FILES-argument takes OCaml-module names only.

Is there a direct way to construct such a mixed-source-library target in omake or do I have to whip up such a function myself? It looks easy enough to built upon OCamlLibrary for e.g.

    OCamlMixedLibrary(library_name, ocaml_modules, foreign_modules)

Hi Chris,

there is an advanced set of macros I developed some time ago for the integration of omake into the now abandoned oasis tool. In particular, the macro OASIS_build_OCamlLibrary looks like it provides what you are searching for:

https://github.com/ocaml/oasis/blob/master/src/plugins/omake/oasis_lib.om#L343

I think the  C objects must be given with .o extension (but I'm not sure).

I haven't found time yet to integrate this macro back into omake, where it sure would fit in well.

Let me know whether it works,

Gerd

Thanks @gerd, your function OASIS_build_OCamlLibrary is massive! I used it as template and extended OCamlLibrary to the following code

public.OCamlMixedLibrary(library_name, ocaml_module_names, foreign_module_names) =
        protected.LIBRARY_NAME = $(file $(library_name))

        protected.OFILES = $(addsuffix $(EXT_OBJ), $(ocaml_module_names))
        protected.FOREIGN_OFILES = $(addsuffix $(EXT_OBJ), $(foreign_module_names))
        protected.CMOFILES = $(addsuffix .cmo, $(ocaml_module_names))
        protected.CMXFILES = $(addsuffix .cmx, $(ocaml_module_names))

        protected.CLIB = $(file $(LIBRARY_NAME)$(EXT_LIB))
        protected.BYTELIB = $(file $(LIBRARY_NAME).cma)
        protected.NATIVELIB = $(file $(LIBRARY_NAME).cmxa)
        protected.SHAREDLIB = $(file $(LIBRARY_NAME).cmxs)

        #
        # Link commands
        #
        $(BYTELIB): $(CMOFILES) $(FOREIGN_OFILES)
                $(OCAMLFIND) $(OCAMLLINK) $(LAZY_OCAMLFINDFLAGS) $(PREFIXED_OCAMLPACKS)  \
                                          $(OCAMLFLAGS) $(OCAMLCFLAGS)  \
                                          $(OCAML_LIB_FLAGS) -a  \
                                          -o $@  \
                                          $(OCamlLinkSort $(CMOFILES)) $(FOREIGN_OFILES)

        $(NATIVELIB) $(CLIB): $(CMXFILES) $(OFILES) $(FOREIGN_OFILES)
                $(OCAMLFIND) $(OCAMLOPTLINK) $(LAZY_OCAMLFINDFLAGS) $(PREFIXED_OCAMLPACKS)  \
                                             $(OCAMLFLAGS) $(OCAMLOPTFLAGS)  \
                                             $(OCAML_LIB_FLAGS) -a  \
                                             -o $(NATIVELIB)  \
                                             $(OCamlLinkSort $(CMXFILES)) $(FOREIGN_OFILES)

        $(SHAREDLIB): $(NATIVELIB) $(CLIB)
                $(OCAMLFIND) $(OCAMLOPTLINK) -shared -cclib -L. -o $@ $(NATIVELIB)

        return $(array $(if $(NATIVE_ENABLED), $(NATIVELIB)),  \
                       $(if $(NATIVE_ENABLED), $(CLIB)),  \
                       $(if $(BYTE_ENABLED), $(BYTELIB)),  \
                       $(if $(CMXS_ENABLED), $(SHAREDLIB)))

The new function adheres to the OMake standard and takes module names not filenames also for the non-OCaml modules. This makes it consistent with the existing {C,OCaml}Library-functions and moreover completely separates compilation and dependency generation of the foreign modules.
