Compiling on macOS

[tmcgilchrist]

First thanks for writing this project, I'm excited to have something like this written in OCaml and have a chance to hack on it. The blog post on https://gopiandcode.uk/logs/log-writing-activitypub.html was great.

I'm having issues with compiling this on macOS. The conan dependency fails with this error in an OCaml 4.14.1 sandbox. Have you encountered this issue? Is it possible to work around not having conan available?

$ opam install conan
The following actions will be performed:
  ∗ install conan 0.0.2

Thanks for the kind words!

w.r.t your error: huh, that's a strange error message.

Have you tried updating your opam repositories? It could be that they're out of date.

Otherwise, the other case is that this is a problem on the conan side itself, maybe the conan developers might be able to help (@dinosaure?).

I use conan for mime handling --- in theory it could be replaced by just shelling out to find, although then again, that might open up another can of worms with compatibility.

It is strange, compiling conan directly from a git checkout works so it must be some packaging issue.

Found mirage/conan#19 which looks to be the same issue.

Fixed in mirage/conan#24
