Libguestfs - Aug 2017 - Ocamlfind can't find hivex

<https://github.com/Chocrates>
Apologies if this is the wrong list, I initially opened a github ticket
before reading that github isn't the right spot.

Trying to compile libguestfs and in the process need to get hivex compiled
and installed.
Hivex compiles and installs fine (I think), but ocamlfind doesn't seem to
pick up hivex after the install causing the autogen.sh script in libguestfs
to fail.

Installation steps:
./bootstrap
./autogen.sh
make
sudo make install

No issues with any of the above commands that I can see, and I noticed that
autogen returned "OCaml bindings ........ yes" so I would expect
ocamlfind
to be able to pick it up.  Ocaml is pretty much a black box to me so not
sure how to debug this from here.

Thanks,

Chris

What distro?

Are the OCaml bindings for hivex actually installed?

What does:

  ocamlfind query hivex

print?

What does the config.log file say?

Oh I see you're using opam to install locally.

I think you'll need to set up an environment variable before running
./configure.  I'm not much of an opam user myself, but it's probably:

  export OCAMLPATH=/home/chris/.opam/4.05.0/lib/ocaml

or maybe:

  export OCAMLPATH=/home/chris/.opam/4.05.0/lib/ocaml:/usr/lib/ocaml

or similar.

You might also want to check /etc/ocamlfind.conf and the opam
documentation.

libguestfs lets you edit virtual machines.  Supports shell scripting,
bindings from many languages.  http://libguestfs.org

Thanks Rich,

Setting the OCAMLPATH and redoing the configure, make and make install
seemed to work.

I installed opam after I couldn't get hivex to install initially, was
hoping that hivex was a package managed by opam I guess.
