[Libguestfs] Building libguestfs from git

Looks like libguestfs build is broken, or not documented properly. I tried (based on http://libguestfs.org/guestfs-building.1.html): git clean -dxf ./autogen.sh autoreconf failes with: autoreconf: running: automake --add-missing --copy --no-force configure.ac:38: installing 'build-aux/missing' configure.ac:221: error: required file 'common/mlcustomize/Makefile.in' not found configure.ac:221: error: required file 'common/mllibvirt/Makefile.in' not found configure.ac:221: error: required file 'common/mlstdutils/guestfs_config.ml.in' not found configure.ac:221: error: required file 'common/mlv2v/Makefile.in' not found Makefile.am:161: error: required directory ./common/mlcustomize does not exist Makefile.am:161: error: required directory ./common/mlv2v does not exist Makefile.am:169: error: required directory ./common/mllibvirt does not exist parallel-tests: installing 'build-aux/test-driver' align/Makefile.am: installing 'build-aux/depcomp' configure.ac: installing 'build-aux/ylwrap' autoreconf: automake failed with exit status: 1 But the autogen.sh continue, ignoring the failure... Finally it fails with: config.status: error: cannot find input file: `Makefile.in' I tried to run it again: ./autogen.sh the autoreconf errors show again, but this time it succeeds, but: $ make -j8 cfg.mk:139: *** gnulib update required; run ./autogen.sh first. Stop. Running ./autoge.sh again does not help. I can build tag v1.40.2, but it is missing some patches in virt-v2v that I need. Thanks, Nir
