I have created my ~/.ocamlinit as follows
let interactive = !Sys.interactive;;
Sys.interactive := false;; (*Pretend to be in non-interactive mode*)
#use "topfind";;
Sys.interactive := interactive;; (*Return to regular interactive mode*)
Toploop.use_silently Format.err_formatter (Filename.concat (Findlib.package_directory "batteries") "battop.ml");;
When I type ocaml at command line, I get the following error:
$ ocaml
Objective Caml version 3.12.1
Cannot find file topfind.
File ".ocamlinit", line 6, characters 60-85:
Error: Unbound module Findlib
#
What is causing this issue and how should I go about for fixing this issue?
(I am on Debian Wheezy)
Edit: I have set an alias for ocaml:
alias ocaml='rlwrap -H /home/nanda/.ocaml_history -D 2 -i -s 10000 ocaml'
With due thanks to dkim, I would post the solution that worked for me. Hope this helps someone else.
To be able to work with the ocaml-batteries-included, I followed this process:
sudo apt-get install ocaml ocaml-batteries-included ocaml-doc ledit rlwrap
rlwrap or ledit is needed to add readline support for OCaml toploop.
Added an alias in .bashrc, to save the commands entered in the ocaml toploop.
alias ocaml='rlwrap -H /home/nanda/.ocaml_history -D 2 -i -s 10000 ocaml'
-H specifies history file name
-D ignores duplicates
-i case insensitive
-s limits the number of commands stored in this file
As mentioned in the comments, I was receiving this error when trying to invoke the ocaml interpreter.
$ ocaml
Objective Caml version 3.12.1
Cannot find file topfind.

I received this error because ocaml-findlib package was not properly installed. I have mamaged to solve this by installing the libfindlib-ocaml-dev package:
sudo apt-get install libfindlib-ocaml-dev
For some people, the issue is solved when findlib package is installed from sources as mentioned here
