does not build with ocaml 5.0

[solsticedhiver]

from what I understand the build fails because of ocaml 5.0.
using ocaml-libvirt-git, the build (either 2.2.0 or 2.3.4 or git) fails with:

We've not built virt-v2v on OCaml 5 yet, but the above error should be easy to fix, simply replace every instance of Pervasives. with Stdlib. in the source code.

This seems to do it, but I bumped into another archlinux issue about

Error: /usr/lib/ocaml/guestfs/guestfs.cmi
       is not a compiled interface for this version of OCaml.```

[rwmjones]

That'll be because the libguestfs package was built with OCaml != 5.

That'll be because the libguestfs package was built with OCaml != 5.

This was indeed not a upstream issue. Fixed in Arch Linux [extra] repo:

https://gitlab.archlinux.org/archlinux/packaging/packages/libguestfs/-/commit/4780699838e5fad70eb8e031438392dced998868

I don't understand why you are saying that. Because your fix includes a patch called ocaml5.patch to help build against ocaml 5.....

I see:

Error: /usr/lib/ocaml/guestfs/guestfs.cmi
is not a compiled interface for this version of OCaml.```

Sorry, I was only referring to this ^^^ issue:
