Looking for:

This ensures that it runs automatically, so that you can just login and run ocaml to have a fully functional ocaml environment set up. If you switch compiler through the opam switch command, you will need to either re-run the command or restart the shell with exit and then bash to push the changes to the environment variables and update the version used by OCaml.

This gives you the REPL loop under bash, which is good for learning. However, for more serious programs you need to write an.

OCaml has many builds for Windows. Each has its own glitches. You have to specify which one you want to use, and what kind of problems you actually have. The question, even though poorly formulated, is interesting, because I and I know I’m not the only one wasn’t able to get any of the above working properly. I’m interested in having feedback from users who managed to get it right.

It appears no one ever invested the time and effort to do a real native port of any? ML language to the windows platform. Only work arounds using unix-emulation environments seem to be available.

This is especially useful since different projects might require different versions of OCaml. On Windows, the best way is to use a traditional setup. Switches are used to have independent sets of dependencies in different projects. Find all the installation instructions for both Unix-like systems and Windows in the sections below:.

After having installed opam, you will need to initialise it, see below. To install opam, you can use your system package manager or download the binary distribution.

The details are available in the above links, but for convenience, we copy a few of them here:. It’s easy to install opam with your system’s package manager on Linux e. Details of all installation methods. All supported Linux distributions package at least version 2.

If you are using an unsupported Linux distribution, please either download a precompiled binary or build opam from sources. Depending on your package manager, you won’t get the latest release of opam.

If you want the latest release, consider installing it through the binary distribution, as shown below:. On Unix, it’s essential to initialise opam, which will if needed install the OCaml compiler. If you already have OCaml installed, opam will use that compiler. If you have installed the binary distribution of opam through the install script, this step should already be done.

If you have installed it through your system package manager, you must initialise opam by running the following command. This method will fetch and initialise the latest version of opam, directly from the official servers:. The first command opam init initialises the opam state stored in a hidden folder.

It also creates a first switch, usually called default , although this is just a convention. A switch is an independent OCaml environment with its own OCaml compiler, as well as a set of libraries and binaries. If you have installed OCaml through your system package manager, the first switch will be set up to use this compiler it is called a “system switch”.

Otherwise, it will build one from source, usually taking the most recent version of OCaml. For instance, it will add what is needed to the PATH variable so that typing ocaml in the shell runs the OCaml binary of the current switch. Please note: At the end of the opam init , you are asked if you want to add a hook to your shell to best integrate with your system. Indeed, in order for the shell to be aware of the tools available in the current opam switch, a few environment variables need to be modified.

For instance, the PATH variable has to be expanded so that typing ocaml in the shell runs the OCaml binary of the current switch. Answering y will provide a better user experience. Now check the installation by running opam –version. It is still useful as an overlay to the default opam repository. This means if a package exists in opam-repository-mingw the opam client will use that information, otherwise it will fall through to opam-repository.

To add opam-repository as an underlay to your opam setup assuming you followed the manual installation from the OCaml for Windows site , you can use:. This assumes you only have the opam-repository-mingw repository for this switch set with a priority of 1. WSL2 is a feature that allows Linux programs to run directly on Windows.

Microsoft has comprehensive installation steps for setting up WSL2. For Educators. With its mathematical roots, OCaml has always had strong ties to academia. Currently, it is being taught in universities around the world, and has accrued an ever-growing body of research. This page will provide you with an overview of the academic rigor that defines the culture of OCaml. For Industrial Users.

With its powerful compile-time guarantees and high performance, several companies rely on OCaml to keep their systems operating both reliably and speedily. On this page, you can get an overview of the companies in the community and learn more about how they use OCaml.
