[PATCH XFSPROGS 1/3] configure.in: Declare a requirement for at least autoconf 2.50

[PATCH XFSPROGS 1/3] configure.in: Declare a requirement for at least autoconf 2.50

[Theodore Ts'o]

On Debian/Ubuntu systems, if autoconf version 2.13 is installed,
autoconf will try to automatically figure out whether autoconf 2.13 or
something more modern is required (since the autoconf maintainers,
curses be upon them, didn't bother to maintain compatibility between
autoconf 2.13 and 2.50).  Unfortunately, the hueristics aren't
perfect, and although the configure.in file looks superficially like
it will be compatible with autoconf 2.13, it isn't.  You will end up
with a number of very subtle compilation failures if you use autoconf
2.13.

So declare a requirement for autoconf 2.50 using AC_PREREQ(2.50).

[PATCH XFSPROGS 3/3] mkfs: Link against libuuid after liblkid

[Theodore Ts'o]

The order in which libraries are searched matters if you are using
static libraries.  Since libblkid uses some functions from libuuid, it
needs to come before libuuid in the link line.

This still doesn't make sense to me.  libxfs explicily overrides
DEBUG in the makefile:

# don't try linking xfs_repair with a debug libxfs.
DEBUG = -DNDEBUG

we really need to figure out why your enviroment doesn't pick this
up, especially as we've never seen that report from anybody else.

Thanks a lot, I've applied our xfsprogs and xfstests patches, and also
ported the change to the xfsdump and dmapi repositories.

I added some debugging statements in libxfs/Makefile, and found this
(see below).

It looks like the problem is that GNU make 3.81 is doing an immediate
expansion of this line in builddefs:

CFLAGS += $(FCFLAGS) $(GCFLAGS) $(PCFLAGS) $(LCFLAGS)

You can get most of this by simply using make V=1, not just in xfsprogs,
but in most projects using silent make output (including those using
automake)

I'm having GNU make 3.81 on most of my test systems as well, so that
alone can't be the whole issue.

for me.  The biggest thing is that you have another directory in your
include path.  How did you add that one? Did you add anything else
special to the ./configure or make command lines?

Yeah, I know about V=1 (and I have been using it), but I wanted to
know which of the many Makefile variables which finally make up
$(CFLAGS) was getting set to which value, and V=1 doesn't do this.

Yes I needed it because I wanted to do a hermetic build; that is, I
didn't want to depend on the version of the acl, attr, dmapi, etc.,
shipped by the distribution.  (This is actually more important when
building xfstests, since I wanted to make sure we used the version of
the xfsprogs headers shipped by the very tip of xfsprogs-dev, since in
the past I've had problems because the distro-shipped header files
were too old.)

The way I did that was by setting the environment CFLAGS to
-I/kbuild/xfstests/bld/include.  And that seems to be the problem.  If
CFLAGS is set as an environment variable, then it's set as a :=, which
means that CFLAGS is set right away, the first time buildmacros is
included.

How about this instead?  A patch like this so that CFLAGS can be
remembered at configure time:

diff --git a/include/builddefs.in b/include/builddefs.in
index 4c8ec64..81ebfcd 100644
--- a/include/builddefs.in

 MALLOCLIB = @malloc_lib@
 LOADERFLAGS = @LDFLAGS@

Then I don't have to set an environment variable when running make; I
just have to pass it to configure.

Given that you are on a Debian-ish environment, did you consider simply
using pbuilder?  I use that regularly to test clean package builds,
without all these weird overrides.

This looks much better, and is indeed similar to some other fixes we
recently had to put in, probably due to changing make behaviour.

If you add a signoff and a proper description I'll put it into all the
repositories.

Can you at least provide the signoff?  I can take care of the rest if
this means I can get it in ASAP.

Ted,

can you please give me a signoff for this patch?  I could probably just
put it in anyway given how trivial it is.  But let's just stick to the
proper protocol if we can.

[PATCH] Build using CFLAGS passed in at configure

[Theodore Ts'o]

In order to build xfsprogs in a hermetic build, we need be able to
pass in -I and -L flags to the compiler and linker, respectively.
This needs to be used by the configure script, but we also need to
make sure these flags are used by the Makefiles as well.

Thanks a lot a Ted!

I've added this to xfsprogs, xfsdump and dmapi.  xfstests actually
already has it, sent in in 2009 by Arek for the same reason you want
it in xfsprogs.  Wish we would have been a bit better to propagate build
system fixes.
