[Qemu-devel] [PATCH 0/2] build: get all *.d files

[Paolo Bonzini]

Avi and Jan experienced more problem with dependencies.  This series
should fix them.

Paolo Bonzini (2):
  build: include qapi-generated/ files in qga/Makefile.objs
  build: get dependency file directories from object file names
  build: do not use hw/kvm/

[Qemu-devel] [PATCH 1/2] build: include qapi-generated/ files in qga/Makefile.objs

[Paolo Bonzini]

No reason to leave them out, and it will ensure that the dependencies
are picked up.  Later we can perhaps move the files to another
directory to avoid ../ usage.

[Qemu-devel] [PATCH 2/2] build: get dependency file directories from object file names

[Paolo Bonzini]

After commit dcff25f2cd8c11a9368cc2369aeb0319c32d9e26, Dependency file
are taken from the directories that have a Makefile.objs file.  This is
not enough, since files can be included from other directories.
So, pick them from directories that have an object file in them.

Couldn't we accomplish that by just adding the dependencies to qga-obj-y in
the top-level Makefile.objs instead?

Yes, but I believe that the better place for these files is
qga/qapi-generated/, so I'm preparing for that. :)

Are you sure? Dependencies are not guaranteed to be in one of the
unnested variables, thought we ran into some issues earlier... In
particular I'm thinking of tcg/*.d and of *.d in .user, .target, those
that are actually recursed into.

obj-y is a nested variable:

  nested-vars += obj-y

  # This resolves all nested paths, so it must come last
  include $(SRC_PATH)/Makefile.objs

$(dir $(obj-y)) contains tcg/ and from there you get tcg/*.d.

The only makefile that doesn't use the nesting mechanism is tests/Makefile.

I think you misunderstood: My worry is

qemu-something: $(obj-y) foo bar baz

obj-y and friends are handled, foo, bar, baz are not. If you checked all
those cases, fine with me. :) Otherwise the new unnesting rule is fine,
but not all "*.d" inclusions could be deleted.

Ah, yes, I did.  The only cases are in the toplevel Makefile (and the
included tests/Makefile), hence this statement left in that Makefile:

+-include $(wildcard *.d tests/*.d)
