[Libguestfs] issue when building/making package from git

[arnaud gaboury]

I am trying to build/install libguestfs from git. My box is Archlinux,
GCC 4.9.1 and all dev tools installed.

If I manually
$ gitclone gitUrl
$ cd libguestfs
$ ./autogen.sh
$ ./configure --someOptions

the build goes until the end and leaves me with binaries.
------------------------------
---

Now I want to install it properly on my machine. Arch use a makepkg
[1] command to build and install packages not in the official repos.

When running
$ makepkg
I have this structure which sounds correct:
libguestfs-git/pkg/
libguestfs-git/src/AllNeededDir_cloned_here

but at one time the build breaks with these errors:
-----------------------------
../src/.libs/libutils.a(
libutils_la-cleanup.o): In function `guestfs___cleanup_xmlBufferFree':
cleanup.c:(.text+0x79): undefined reference to `xmlBufferFree'

collect2: error: ld returned 1 exit status
Makefile:1598: recipe for target 'virt-p2v' failed
-------------------------------------


I can't figure out why the binaries build manually and not using
makepkg(). The only things I see are CFLAGS and LDFLAGS passed to makepkg().
Here are part from /etc/makepkg.conf:
------------------------------
CPPFLAGS="-D_FORTIFY_SOURCE=2"
CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector
--param=ssp-buffer-size=4"
CXXFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector
--param=ssp-buffer-size=4"
LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro"
#-- Make Flags: change this for DistCC/SMP systems
MAKEFLAGS="-j 8"
#-- Debugging flags
DEBUG_CFLAGS="-g -fvar-tracking-assignments"
DEBUG_CXXFLAGS="-g -fvar-tracking-assignments"
------------------------------

Is there any flag which can prevent to build libguestfs?
I even tried to add some more flags regarding xml2 (not sure it is
worth) but it didn't change.
------------
 -I/usr/include/libxml2
 -lxml2 -lz -ldl -lm
------------------------

Thank you for any suggestion.
