This is a bug in the tarball (in build-aux/ltmain.sh). You should be
able to work around it by rebuilding that file, by doing:
libtoolize --force
before building in the ordinary way. I'll modify the scripts I use to
create the tarball so it doesn't add this artifact in future versions.

It's strange because the program above doesn't call any Augeas
functions in libguestfs. Perhaps you're compiling a different
program?
Anyway, I'm pretty sure this _is_ a bug in libguestfs, owing to the
way we try to add rules to Augeas, which has been a constant source of
pain. Ask Pino about that code.
Rich.

libguestfs init problem
by fu lirong
Hi ,all :
thanks for helping me ! I am using libguestfs-1.28.1 on ubuntu
12.04 to manage vm disk created by KVM. I downloaded
libguestfs-1.28.1.tar.gz ,and then executed
(1) ./autogen.sh (2) ./configure (3) make (4) make check .there is
the error.
/usr/Libvmi/libguestfs-1.28.1/run --test guest-aux/make-fedora-img.pl
md_create: feature 'mdadm' is not available in this
build of libguestfs. Read 'AVAILABILITY' in the guestfs(3) man page for
how to check for the availability of features. at
/usr/Libvmi/libguestfs-1.28.1/tests/guests/guest-aux/make-fedora-img.pl
line 103.
/usr/Libvmi/libguestfs-1.28.1/run: command failed with exit code 2
make[2]: *** [stamp-fedora-md.img] Error 2
make[2]: Leaving directory `/usr/Libvmi/libguestfs-1.28.1/tests/guests'
my questions are:
(1) I googled the problem. In guestfs(3) man page ,It seems like that I
don't install FUSE. In fact ,I have no idea about so many packages in
libguestfs such v2v , src ,tools,tests and so on ,and I want to know where
to find such kind information.
(2) I find that guestfsd is the daemon in guest, so ,do I have to modify
the guest(such as run guestfsd in guest)?
(3) I just start the example : Inspect a disk image and display
operating systems it may contain. so I copy the code under
/libguestfs-1.28.1/prog.c , then I executed
(1) cc prog.c -o prog `pkg-config libguestfs --cflags --libs` ,
(2)./prog /var/lib/libvirt/images/vm.img
