description: """
Michelson is a language for writing smart contracts on the Tezos blockchain.
This package provides a Coq encoding of the syntax and semantics of Michelson,
automatically generated by the Ott tool. Also included is a framework called Mi-Cho-Coq
for reasoning about Michelson programs in Coq using a weakest precondition calculus."""

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-mi-cho-coq.0.1 coq.8.10.1
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.10.1).
The following dependencies couldn't be met:
  - coq-mi-cho-coq -> ocaml >= 4.07.1
      base of this switch (use `--unlock-base' to force)
No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-mi-cho-coq.0.1
