I’ve just installed opam and ocaml on Debian Testing via apt, then did
opam install utop, added ``eval `opam config env``` to my ~/.bashrc, and I can now start up and use utop as a calculator.
Utop tells me the versions I have are:
Welcome to utop version 2.0.1 (using OCaml version 4.02.3)
I wanted to install Core (to follow along with RWO), and did
opam install core to get it. It downloaded and installed a bunch of packages, and seemed to have succeeded. If I try installing again, I get:
$ opam install core [NOTE] Package core is already installed (current version is 113.33.03).
Now when I start utop and do “
open Core.Std;;”, it tells me “
Error: Unbound module Core”.
Did I install Core correctly?
Is there some other config to be done to get Core properly installed?
