Re: [Libguestfs] libguestfs binaries missing when built from source code



Hi Richard,
 
Thank you for the feedback!
I have been following them and facing the below issue while building the same:
…..
podwrapper.pl: wrote virt-v2v-test-harness.1
podwrapper.pl: wrote ../../html/virt-v2v-test-harness.1.html
touch stamp-virt-v2v-test-harness.pod
ocamlfind ocamlopt -g -annot -warn-error CDEFLMPSUVYZX-3 -package str,unix,libvirt -I ../../src/.libs -I ../../gnulib/lib/.libs -I ../../ocaml -I ../../mllib -I ../../v2v -c v2v_test_harness.ml -o v2v_test_harness.cmx
  AR       libv2vth.a
File "v2v_test_harness.ml", line 205, characters 14-26:
Error: Unbound value D.create_xml
make[2]: *** [v2v_test_harness.cmx] Error 2

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/rpmbuild_oldlib/BUILD/libguestfs-1.30.3'
make: *** [all] Error 2
 
I have listed the available ocaml packages installed on my server:
ocaml-runtime-3.11.2-2.el6.x86_64
ocaml-findlib-devel-1.2.5-5.el6.x86_64
ocaml-fileutils-devel-0.4.0-4.1.el6.x86_64
ocaml-libvirt-0.6.1.0-6.4.el6.x86_64
ocaml-3.11.2-2.el6.x86_64
ocaml-findlib-1.2.5-5.el6.x86_64
ocaml-ounit-2.0.0-17.el6.x86_64
ocaml-fileutils-0.4.0-4.1.el6.x86_64
ocaml-camlp4-3.11.2-2.el6.x86_64
ocaml-gettext-devel-0.3.3-3.5.el6.x86_64
ocaml-libvirt-devel-0.6.1.0-6.4.el6.x86_64
ocaml-ounit-devel-2.0.0-17.el6.x86_64
ocaml-gettext-0.3.3-3.5.el6.x86_64
 
Is it because of an incorrect version of ocaml-libvirt?
According to that guide the required ocaml-libvirt is ocaml-libvirt ≥ 0.6.1.5 and unfortunately the available version in their official page is only 0.6.1.4.
 
Any idea what is missing here?

Emlyn Jose

In the Fedora packaging we put virt-resize into libguestfs-tools-c, but in the upstream sources the binary is built in the resize/ subdirectory.

Running ‘make’ builds all the binaries.
 
If you mean the binary is not being created during ‘make’, then it's likely you have some missing build dependencies, most probably the OCaml compiler.

virt-p2v converts physical machines to virtual machines.  Boot with a live CD or over the network (PXE) and turn machines into KVM guests.
