Opam build failure: menhirLib not found about merlin HOT 8 CLOSED

I have some problem understanding your configuration, and I can't reproduce this error.

How did you install the ocaml system? Did you use brew?

from merlin.

I used brew to install ocaml and brew to install opam.

from merlin.

It seems that compiling ocaml with opam seems to have fixed the error. I must have misunderstood how opam works.

from merlin.

Well, it should have worked with system compiler, so there is a problem somewhere…
Any way, it is safer to use opam managed compiler.

I've recently came about a similar error. I think the issue was:

1. Merlin was using the system's ocamlbuild which was using the system's ocamlfind

2. menhir, etc. were installed using opam's local ocamlfind.

from merlin.

I plan to tag v1.1 this week-end. It would be nice to close this issue, but I don't understand why this is causing problem…

Normally, make is called from opam, so its environment use opam's PATH ?!

from merlin.

It is using opam's PATH. But I don't think it's using opam's ocamlbuild. But it's also using the system's ocamlbuild @ /usr/bin/ocamlbuild when using the "system" ocaml installation. For example on the system where I've encountered the problem:

opam switch system followed by eval opam config env (don't know how to escape backquotes in md)

1. which ocamlbuild -> /usr/bin/ocamlbuild

2. which ocamlfind -> ~/.opam/system/bin/ocamlfind

Which is obviously wrong...

In any case this is definitely not a bug with merlin so you can safely close this. I'm just wandering whether the OPAM people should be aware of this...

from merlin.

Oh I see! That's probably what happened.

A solution may be that opam exports OCAMLFIND_CONF / OCAML_PATH variables… I'll ask OPAM people.
