No OCaml5 on Opam 2.2.0 / Windows

I have installed Opam 2.2.0 on Windows and opam switch list-available doesn’t show any OCaml5 switches.

I have checked the repo:

$opam repo --all
# Repository # Url
          # Switches(rank)
default      git+https://github.com/ocaml-opam/opam-repository-mingw
          <default> default 4.14.1+msvc64c mingw fresh 4.14.1+msvc32c

Then the command opam init git+https://github.com/dra27/opam-repository.git#windows-initial which is recommended when installing doesn’t seem to have an effect.

And I note that opam-repository-mingw/packages/ocaml at sunset · ocaml-opam/opam-repository-mingw · GitHub doesn’t include OCaml5 variants.

Opam 2.2 support windows with the default opam repo. You should not use the opam-repository-mingw repo.

I suspect you’re looking at outdated docs such as opam - opam 2.2.0~beta2 - Windows OCaml

The latest release is opam - Platform Blog

Yes, I had installed the 2.2.0-beta2, then installed afterward the 2.2.0 on it.

Ok… then Delete (or rename) C:\Users\frede\AppData\Local\opam and typing $opam init --reinit -ni fix my issue.

I just should upgrade to 2.2.1…

2.2.1 installed, but that fails on installing lwt or xdg. The Dune file search a x86_64-w64-mingw32-gcc.exe file… and on Cygwin, there are no .exe suffixes.

Try (re)installing mingw-w64-shims.
If you still have issues, please post the logs so it’s easier to investigate
