Proof of the Four Color Theorem
This library contains a formalized proof of the Four Color Theorem, along
with the theories needed to support stating and then proving the Theorem.
  This includes an axiomatization of the setoid of classical real numbers,
basic plane topology definitions, and a theory of combinatorial hypermaps.

Dry install with the current Coq version:

Command

opam install -y --show-action coq-fourcolor.1.2.3 coq.8.14.0

Return code

5120

Output

[NOTE] Package coq is already installed (current version is 8.14.0).
The following dependencies couldn't be met:
  - coq-fourcolor -> coq < 8.14 -> ocaml < 4.06.0
      base of this switch (use `--unlock-base' to force)
Your request can't be satisfied:
  - No available version of coq satisfies the constraints
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-fourcolor.1.2.3
