ocaml-ctypes: use of undeclared identifier 'uint64'

[skymoo (Adam Mercer)]

Getting the following when trying to build ocaml-ctypes on Sierra:

It looks like our port is way out of date. Latest version is 0.13.1.

[mf2k (Frank Schima)]

I tried updating to the latest version, but it fails to build because:

ocamlfind: Package `integers' not found

It looks like we need to create a port for ocaml-integers. ​https://github.com/ocamllabs/ocaml-integers

[hapaguy (Brian Kurt Fujikawa)]

Any updates on this issue? Workarounds? Port science/root6 is dependent on ocaml-ctypes, and the undeclared uint64 issue is preventing its installation.

[pmetzger (Perry E. Metzger)]

We need to fix a bunch of ocaml infrastructure. Given that these problems would be straightforward. I'm adding myself to the ticket for now.

[pmetzger (Perry E. Metzger)]

Note that I'm trying to come up with a comprehensive solution right now. If there's a rush on this, I'd recommend that you help me manually packaging the dependents (which include ocaml-integer and ocaml-topkg) for now.

[pmetzger (Perry E. Metzger)]

So I'm currently working on getting some changes made to OPAM to make it possible to cleanly track OCaml packages going forward. This may take a little while to finish.

[skymoo (Adam Mercer)]

Thanks. I know next to nothing about OCaml, I tried packaging the dependencies when this originally came up but didn't get very far.

[pmetzger (Perry E. Metzger)]

It's a pretty complicated ecosystem and we were without an OCaml package maintainer for a long time. Sorry about the delay. If you can give me a list of OCaml packages you're dependent on I'll try to prioritize them.

[skymoo (Adam Mercer)]

The priority for me is getting the port mentioned in this ticket, i.e. ocaml-ctypes, building with a newer Xcode.

[pmetzger (Perry E. Metzger)]

I'll see what can be done there later this week.

[skymoo (Adam Mercer)]

No rush, this has been waiting a few months without major issue. I can wait until you have the infrastructure ready.
