Trying with Mirage, and llikely with the newly released ocaml-solo5 (1.0.0) supporting OCaml 5.x -- and OCaml 5.3 being released

In a make lock, I get the following error:

opam-monorepo: [ERROR] Some dependencies cannot be built with dune!

opam-monorepo requires that all dependencies use dune as their build system.

These dependencies (possibly transitive) don't use dune as their build system:
- ocaml-compiler

Now, I understand there's been some shuffling around with opam package names and ocaml 5.3 - but I'm a bit stuck what opam-monorepo intends to do here. Would it be possible to fix that?

This has as well been reported on discord on the mirage channel. Would any of those knowing more details of opam-monorepo be able to take a look into how to deal with OCaml 5.3? Thanks a lot!

I have this same issue with OCaml 4.14.1

[hannesm]

Please have a look in #407. It would be great to get that merged and released ASAP. Of course any "better" fix is very welcome.

The issue I ran into (and @PizieDust as well) is that albatross has specified a bound on ptime >= 1.2.0, which is not available in the dune-opam-overlays repository. But the ocaml-compiler issue shadowed the underlying issue.

Now, of course it would be great if you could as well put the ptime 1.2.0 package into the dune-opam-overlays repository. In the meantime, I as well opened ocaml/opam-repository#27417 as a workaround.

It would also be nice if your code would print not only the first error, but as well other errors if there are some.
