I tried to install xs on my Linux Ubuntu 18.04 LTS machine but opam give some strange errors

My opam version is 1.2.2.

Do you have any suggestions how to proceed?

You are using a very old opam version and old OCaml. To get a current version of opam:

add-apt-repository ppa:avsm/ppa
apt update
apt install opam

For more info, check out the opam install instructions: https://opam.ocaml.org/doc/Install.html

Right now, I'm using opam 2.0.7, so check with opam --version that it is atleast 2.x. Just to be sure, let's use the optimized version of the latest OCaml release:

opam switch create 4.10.0+flambda 4.10.0+flambda

This creates a new opam switch called '4.10.0+flambda` that's pinned to version 4.10.0+flambda (flambda is the optimizing compiler). Now simply just run the install command again:

opam pin add xs https://github.com/smabie/xs.git

Let me know if this works for you. Thanks for trying out xs!

Ah, I would expect it was an old version. Excellent, it works now.
