[Libguestfs] issue when building/making package from git

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' ../src/.libs/libutils.a(libutils_la-cleanup.o): In function `guestfs___cleanup_xmlFreeDoc': cleanup.c:(.text+0x99): undefined reference to `xmlFreeDoc' ../src/.libs/libutils.a(libutils_la-cleanup.o): In function `guestfs___cleanup_xmlFreeURI': cleanup.c:(.text+0xb9): undefined reference to `xmlFreeURI' ../src/.libs/libutils.a(libutils_la-cleanup.o): In function `guestfs___cleanup_xmlFreeTextWriter': cleanup.c:(.text+0xd9): undefined reference to `xmlFreeTextWriter' ../src/.libs/libutils.a(libutils_la-cleanup.o): In function `guestfs___cleanup_xmlXPathFreeContext': cleanup.c:(.text+0xf9): undefined reference to `xmlXPathFreeContext' ../src/.libs/libutils.a(libutils_la-cleanup.o): In function `guestfs___cleanup_xmlXPathFreeObject': cleanup.c:(.text+0x119): undefined reference to `xmlXPathFreeObject' 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.
