Error: Unbound module Toploop, when trying to install merlin.

I'm new to Ocaml. I'm trying to use merlin to get auto-completion in vim.

Ocaml: version 4.07.0

Solution

  • Archlinux splits the compiler-libs package from the main ocaml package. You need to install ocaml-compiler-libs or use an opam-managed compiler.
