Bob

Bob is a lackadaisical teenager. In conversation, his responses are very limited.

Bob answers 'Sure.' if you ask him a question.

He answers 'Whoa, chill out!' if you yell at him.

He says 'Fine. Be that way!' if you address him without actually saying anything.

He answers 'Whatever.' to anything else.

Error: No implementations provided for the following modules:

Command exited with code 2.

Reason

You are using a module in your solution, in this case the Str module, and the OCaml build tool is not aware of this.

Solution

Add the module you are trying to use to the ocamlbuild build options.

Modify the test.native directive of the Makefile to be:

1
2
test.native: *.ml *.mli
    @corebuild -quiet -pkg oUnit -pkg str test.native

Note the additional -pkg str option.

Getting Started

For installation and learning resources, refer to the exercism help page.

Installation

To work on the exercises, you will need Opam and Core. Consult opam website for instructions on how to install opam for your OS. Once opam is installed open a terminal window and run the following command to install core:

1
opam install core

To run the tests you will need OUnit. Install it using opam:

1
opam install ounit

Running Tests

A Makefile is provided with a default target to compile your solution and run the tests. At the command line, type:

1
make

Interactive Shell

utop is a command line program which allows you to run Ocaml code interactively. The easiest way to install it is via opam:

1
opam install utop

Consult utop for more detail.
