[Omake] A question about the OCamlPackage function and its use...

[Francisco Jos? Valverde Albacete]

Hi,

I am trying to switch from OCamlMakefile to Omake but I continually trip 
over the smallest tasks. My last stumble was to try to make a package 
and then a library out of it.

The idea I got from the OCaml manual was (stripped to the essentials)
1) Compile the individual files with -for-pack
    ocamlc -for-pack package -c foo.ml
    ocamlc -for-pack package -c bar.ml
2) Make a package with the chosen name:
    ocamlc -pack -o package.o foo.cmo bar.cmo
3) If you want to, pack the thing into a library, say package.cma

I now understand that OCamlPackage can only accomplish 2 and tries to 
trigger 1, but I find it impossible to pass -for-pack to the components 
*without* passing -for-pack to the actual package (which  would result 
in a structure Package.Package.Foo, for instance)

My best effort so far has been to build MyOCamlPackage and try to hack 
things in there, but I get the twice-packed configuration above...

BElow is how I used to do it (using OCamlPackage). I am trying to redefine

public.OCAMLFLAGS =
     OCAMLFLAGS += -for-pack <pacakge>
     export

locally in the body of OCamlPackage, so that when the *.ml(i)'s are 
compiled, my extended variable would be used, but I am not suceeding at 
all. Anyway, I don't know how to roll back to OCAMLFLAGS so that when I 
exit OCamlPackage the old value is still there.

Any ideas?Any help would really be appreciated.
