How to fix the Unbound module Graphics in an ocaml project

From ~/pr/gitl/ocaml-gol In a constant effort to learn new programming languages, I'm currently trying to use ocaml , a free and open-source general-purpose, multi-paradigm programming language maintained at the Inria . It's basically an extension of Caml with object-oriented features. I'm mostly interested by its functionnal and pattern matching features but the module part of the language can be a bit difficult to understand for someone with little to none ML (Meta Language) background.   The error When trying to use the graphics module to create a graphical window and go just a little further than the simplest helloworld program, here is the result : If the project uses dune : (executable (name ocaml_project) (libraries lwt.unix graphics) ) with this code : let () = Printf.printf "Hello, world!\n";; Lwt_io.printf "Hello, world!\n";; Graphics.open_graph " 800x600";; The first times I built this project running the du

Headers-date switches to revision 14

This little ruby project , introduced earlier in this post , used to test the GNU headers' dates for a complete project, just switched to revision 14. This project, and in the near future all of my public projects, uses an online coverage tool provided by  coveralls.io . Coveralls presentation This online coverage tool is used to measure which source code is executed when a particular test suite runs. So you can know which part of a project isn't yet tested and improve software quality. 2022 update This project is not hosted at github anymore, I moved it to bitbucket and it do not use coveralls anymore. You can always execute unit tests or compute code coverage locally though. Since I do not use this project anymore obn a weekly basis, I can only test it once every 3 or 4 months. The text output actually works. The GTK-based GUI may be broken though.
