Hi Libguestfs team,

I'm trying to build guestfs on Ubuntu 22.04, but getting below error. #17 8.021 checking for OCaml findlib package augeas... not found #17 8.024 configure: error: the OCaml module 'augeas' is required

By guestfs-building doc I need to get the package from https://people.redhat.com/~rjones/augeas/ <https://people.redhat.com/~rjones/augeas/>. But there is not instructions on how and where to place the package .tar file? I downloaded the .tar and untar it to /usr/local/ but that does not help. 

Can anyone please help on how to resolve this issue?

(1) Rich announced the new external dependency on "ocaml-augeas" in <http://mid.mail-archive.com/20230121115301.GR7636@redhat.com>. According to that message, Debian will have to package ocaml-augeas, and that package will eventually trickle down to ubuntu (probably not an LTS release though). ((2) I've not tried building ocaml-augeas myself from the upstream tarball, I just rebuilt the Fedora SRPM on RHEL9, and installed that. This way I can develop upstream libguestfs on RHEL9. Once we rebase libguestfs to upstream in RHEL9, we'll inherit the new dependency, and we are likely going to have to package ocaml-augeas in RHEL9. Not sure.) (3) Peeking into the 0.6 release tarball now, I don't think just extracting it suffices. There's a configure script in it, so you need to build and install it. And once you do, I *think* the libguestfs build system should find it, via "ocamlfind". In case you installed ocaml-augeas in a nonstandard path, then you might have to extend your OCAMLPATH environment variable, namely with the directory where ocaml-augeas installed its the META file. Do this before building libguestfs; I *think* it is through OCAMLPATH how "ocamlfind" locates OCaml modules. Laszlo
