Can’t use Sqlite3


I try to use the sqlite3 library from the system (Debian 9)… it loads but doesn’t declare the Sqlite3 module :

loyer@ks3001154:~$ ocaml                                                    
        OCaml version 4.02.3                                                
# #load "sqlite3/sqlite3.cma";;
# open Sqlite3;;
Error: Unbound module Sqlite3

Don’t you need to separately do the #directory "sqlite3";; directive, to get CMI files accessible?

This makes me think that I have no .cmi installed. Verifying, I have just found the libsqlite3-ocaml-dev which solves the issue.
