Hi,

Here is v2 of the out-of-tree build. There have been a number of
changes following review and also inclusion of Thomas' ppc64 patch
which completes the set.

The biggest change is the way I deal with creating build directories.
There is now a make variable called OBJDIRS which sub-builds can add
to. I had originally tried to be clever by expanding OBJDIRS into a
bunch of templated mkdir's which could then be set as
order-on-prerequisites as suggested by Drew. However it turns out to
be very hard to add the directory of the target as a prerequisite even
using hacks like GNU's secondary expansion. In the end I just created
a directories target and made sure the all: target had it as the first
thing. This breaks if someone tries to build an individual file
without first building the tree but I assume most people don't build
like that. If anyone else can come up with a neater solution I'm all
ears ;-)

Finally I've added a .travis.yml recipe. This really only works for
github hosted repos but its better than nothing. Evidently the cross
compilers complain about:

  lib/report.c:38:17: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
  assert_msg(len < sizeof(prefixes), "%d >= %lu", len, sizeof(prefixes));

and:

  lib/report.c:38:2: error: format '%lu' expects argument of type 'long unsigned int', but argument 6 has type 'unsigned int' [-Werror=format=]
  assert_msg(len < sizeof(prefixes), "%d >= %lu", len, sizeof(prefixes));

But these can be addressed with separate patches.

This is a first step to enabling out-of-tree builds for
kvm-unit-tests. When you invoke configure like this:

  ../tree.git/configure [args]

It will detect we the case and:

  - link ../tree.git/Makefile to the build-dir
  - link ../tree.git/$(arch) and test scripts
  - link ../tree.git/run_tests.sh
  - ensure lib is created with a correct lib/asm
  - set SRCDIR in the config.mk

Whitespace in $srcdir is going to break the build.  I think that we
cannot prevent that by escaping as `make` is notoriously bad in that
regard.  Aborting sounds better and maybe something like this could
work:

  ln -sf "$srcdir" srcdir
  srcdir=srcdir

I'm ok with this version if the solution would not be simple. :)

I think it's pretty common to have things break horribly if there's
whitespace in $srcdir.

Just don't call your srcdir "little bobby tables; rm -rf /".

Pass -C $(SRCDIR) to the git command that generates the build-head
stamp.

Setting the VPATH prompts make to search VPATH for source files. There
are still some fix-ups needed for linking and including other Makefile
fragments for each architecture.

I would of thought VPATH took care of this but apparently not.

This is slightly clumsy way to ensure the directory structure for the
out-of-tree build is made first. The PHONY target is depended on by
make all first which runs mkdir for all OBJDIRS.

If an architecture target needs deeper nesting it needs to add
directories to OBJDIRS so it can be picked up by the directories rule.

Could you add a $(shell $(mkdir -p $(@D)) here instead, and a $(shell
$(mkdir $(LIBFDT_objdir)) to cater for the nested libfdt makefile?

Sorry if I have asked this already.

We still need to tell the compiler the correct search path for finding
headers and the like. This is slightly complicated by the "dynamic"
asm search path which is in our build tree but (may be) symlinked to
the right architectures headers.

Also we explicitly include SRCDIR for the linking scripts as VPATH
doesn't seem to find them well enough.

Also update OBJDIRS to include lib/x86.

asm search path which is in our build tree but (may be) symlinked to

Also we explicitly include SRCDIR for the linking scripts as VPATH

Also we set OBJDIRS for the lib/arm, lib/arm64 and generated
asm-offset files.

This adds a TravisCI build matrix to test all the various build
combinations of architecture and with/without out-of-tree builds. It
currently fails because the Trusty compilers have some issues with
various format strings and unsigned/signed comparisions but these can
be fixed up later.

I noticed few cases that don't work:
 - SRC_DIR path contains whitespace
 - SRC_DIR was `./configure`d for another arch
 - SRC_DIR isn't clean (up-to-date results won't be rebuilt out-of-tree)
 - reconfiguring --arch in a out-of-tree directory

The in-tree build still works, out-of-tree in decent cases, Makefile
changes are reasonable, and reviewers seem content in front of a
first-grade bikeshedding material ...

Applied, thanks.

(Should be fixed now.)
