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.

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.

libguestfs init problem
by fu lirong 05 May '15

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 libguestfs: error: aug_init: aug_init: / (flags 48): Syntax error in lens definition: /usr/share/guestfs/guestfs_lvm_conf.aug:28.25-.40:Could not load module Quote for Quote.do_dquote /usr/share/guestfs/guestfs_lvm_conf.aug:28.25-.40:Undefined variable Quote.do_dquote /usr/share/guestfs/guestfs_lvm_conf.aug:29.31-.44:Could not load module Rx for Rx.relinteger /usr/share/guestfs/guestfs_lvm_conf.aug:29.31-.44:Undefined variable Rx.relinteger /usr/share/guestfs/guestfs_lvm_conf.aug:32.20-.23:Undefined variable int /usr/share/guestfs/guestfs_lvm_conf.aug:40.17-.29:Undefined variable flat_literal thanks for your patience, I Appreciate it so much . sincerely
