Opam2 compilation fails about homebrew-ocaml HOT 10 CLOSED

@rusty-key - no problem. I was sharing that in case you still needed to get up and running! I expect that that patch will be present in opam2 rc4 which is due out "soon".

Same here!

That looks like safe-string issue.

@tantignac or @rusty-key could one of you please do the install with -b -d so that we can get more details about the failure.

@dbuenzli, not sure how to extract more information. Here is a log with backtrace:

I tweaked formula to disalble treating warnings as errors with

# ...
ENV["OCAMLPARAM"] = "warn-error=-a,w=-3,_"
# ...

Now make produces real error:

==> make

Maybe this will help

from homebrew-ocaml.

It does - you’re building opam with OCaml 4.07.0 which clearly doesn’t work.

from homebrew-ocaml.

@rusty-key I believe that something like this should work:

patch do
  url "https://github.com/dra27/opam/commit/818aedbcf064bf377384b75d9fb13d521956ee45.diff"
  sha256 "02959b1e7c69517da8a69dd7bef6f70153a6b34ee156d9b56f8ac4dd5610af21"
end

@dra27, I already built opam2 from source and too afraid to try reinstalling with brew. Is there a way I can help without installing? Maybe there is a dry run?

from homebrew-ocaml.

@rusty-key Once #12 is merged you should be good to go. I tested it and it seems to build on 4.07.0 that is shipped with brew.
