Hi,
    When I apply some changes to Xen-4.1.2(mainly change the files in
tools/libxl) , then comile it , I meet the problem as follow :
         MLI       op.mli
         MLI      op.cmi
         MLI       partial.mli
         MLI      partial.cmi
         MLI       packet.mli
         MLI      packet.cmi
         MLC      op.cmo
         MLC      partial.cmo
         MLC      packet.cmo
         MLC      xs_ring.cmo
         MLI       xb.mli
         File "xb.ml", line 27, characters 7-26:
         Error: Unbound module Mmap
         make[6]: *** [xb.mli] Error 2
         rm packet.mli partial.mli op.mli

    I'm sorry I'm a new comer , so please could you tell me how to solve
this problem?
    Thanks:)

It's unclear to me why your modification to libxl would affect the Ocaml
part. You'd better be more specific on what you did and what you tried
to achieve.

I just want to apply some patches of xen-4.3 to xen-4.1.2 , and the all the
changed codes are in tools/libxl , nothing to ocaml part .  May be the
problem of Makefile?

Could be. But we can never know until you make it clear what you've
done.

Is this still about applying my RFC patches about memory migration? I
seriously doubt it (OCaml, what is OCaml? :-O) but, as I said, I really
don't know what would happen if applying them to any old (or even new,
actually) version of Xen, neither I plan to do much investigation on it.

If it's not about them, sorry for interrupting.

If it is, and you are interested in the feature --as I already said a
couple of time-- make your interest, your availability, your knowledges,
etc., more explicit, and I'll be happy to bring you on-board for the
development of it (which, again, is still ongoing).

Regards,
Dario

Yes, I've move your patches about memory migration to Xen-4.1.2, and then
the problem comes. I dont' know why. Does ocaml has any relationship with
the codes in libxl/tools?

Could you check if there is any other error preceding the ocaml ones.

Before the ocaml ones, I met the problem as following :
     libxenlight.so: undefined reference to 'yajl_gen_array_close
     libxenlight.so: undefined reference to 'yajl_gen_integer'
     libxenlight.so: undefined reference to 'yajl_alloc'
     .......
And I add the -lyajl option in the Makefile then the problem solved, and
the ocaml ones come.

Ok, could you stop doing that or, if you want to continue doing that,
stop asking?

I'm sorry, I don't want to sound rude, but what you are trying to do is
_supposed_ to be broken and unsupported, so there is very few point in
asking for support about it.

I've told you countless times that, if you want to be involved in
properly developing that feature, we can arrange something out.

I'm telling this one more and last time here. If you want to
participate, tell me. If you want to keep trying apply an incomplete and
non-fully working RFC to some old version of Xen, go ahead, but, please,
avoid bothering the list.

Regards,
Dario

Does it work if you build pristine 4.1.2 without your changes?

You could try "git clean -fdx tools/ocaml" to wipe out any vestiges of
an old build otherwise as Wei says you will need to shows us your
patches.
