Tried again with new clean checkout, this change fixes the issue.

The next issue is same as libguestfs:

autoreconf: running: automake --add-missing --copy --no-force
configure.ac:30: installing 'build-aux/missing'
configure.ac:102: error: required file 'common/options/Makefile.in' not
found
configure.ac:102: error: required file 'common/mlaugeas/Makefile.in' not
found
configure.ac:102: error: required file
'common/mlcustomize/Makefile.in' not found
...
parallel-tests: installing 'build-aux/test-driver'
gnulib/lib/Makefile.am: installing 'build-aux/depcomp'
autoreconf: automake failed with exit status: 1

autogen.sh ignores the error and continue, and finally failing with:

config.status: error: cannot find input file: `Makefile.in'

Looking in common we have:

$ tree common
common
├── mlgettext
│   └── common_gettext.ml
└── mlstdutils

I tried you other suggests for git submodules:

$ git submodule init
Submodule 'common' (https://github.com/libguestfs/libguestfs-common)
registered for path 'common'

$ git submodule update
fatal: destination path '/home/nsoffer/src/virt-v2v/common' already
exists and is not an empty directory.
fatal: clone of 'https://github.com/libguestfs/libguestfs-common' into
submodule path '/home/nsoffer/src/virt-v2v/common' failed
Failed to clone 'common'. Retry scheduled
fatal: destination path '/home/nsoffer/src/virt-v2v/common' already

fatal: clone of 'https://github.com/libguestfs/libguestfs-common' into
submodule path '/home/nsoffer/src/virt-v2v/common' failed
Failed to clone 'common' a second time, aborting

So I tried:

rm -rf common/*

$ git submodule update
Cloning into '/home/nsoffer/src/virt-v2v/common'...
Submodule path 'common': checked out
'8c42f772614b44a8cb974afa904ec9f518431ab2'

$ ./autogen.sh

This seems to fix the issue, but make failed with:

$ make -j8
There seems to be no Makefile in this directory.
You must run ./configure before running 'make'.
make: *** [GNUmakefile:108: abort-due-to-no-makefile] Error 1

$ ./configure

Works, but now make fail with:

$ make -j8

Sounds like files from the old directory were still around after a git
pull.  Removing common/ was the right thing to do.

This happens because the Fedora package ocaml-libguestfs-devel is not
installed.  ./configure should have spotting this was missing, so this
is a bug in virt-v2v.

Re: [Libguestfs] How to build virt-v2v after the project was separated

I've pushed a few commits which fix various aspects of the build and
may improve things for you:

commit d5ce9c91469d3d384aa32735453a1f8a20d4ec25
Author: Richard W.M. Jones <rjones@redhat.com>
Date:   Mon Nov 18 10:11:57 2019 +0000

    tests: Add TESTS_ENVIRONMENT in a couple of makefiles.
    
    We were accidentally testing the installed virt-v2v rather than the
    locally built one.

commit fffa7732c5d4899217c36985f1ef753d2469f1cd
Author: Richard W.M. Jones <rjones@redhat.com>
Date:   Mon Nov 18 09:46:49 2019 +0000

    m4: Relax dependency on libguestfs versions.
    
    1.41 was only required to run a single test, but in all other respects
    1.40 works fine.  Relax the dependency and fix the test instead.
    
    Thanks: Nir Soffer.

commit 8cab32c0eb4b455d7f0700ef5966eed3a23b6327
Author: Richard W.M. Jones <rjones@redhat.com>
Date:   Mon Nov 18 09:45:05 2019 +0000

    m4: Remove daemon checks and dependency on hivex.
    
    Now that we've split out virt-v2v, there's no daemon, and hivex is
not
    required (since it is only used through the guestfs API).

commit 48afc3b004e44feaf3844c5eeb96e2a1aadbeb03
Author: Richard W.M. Jones <rjones@redhat.com>
Date:   Mon Nov 18 09:44:12 2019 +0000

    m4: Check that ocaml 'guestfs' module is available.
    
    It is required to compile virt-v2v after we split out libguestfs and
    virt-v2v.
    
    Thanks: Nir Soffer.

Rich.

I tried with new checkout:

rm -rf virt-v2v
git clone ...

So this must be another issue.

With current master building virt-v2v succeeds, thanks!

I think we still have an issue with new checkout, having to delete common/
and update the submodule.
