These sets of axioms should be proved coherent by mixing up the deliverable model and the setoid model (both are presented in Martin Hofmann' thesis).""" flags: light-uninstall url { src: "https://github.com/coq-contribs/rational/archive/v8.5.0.tar.gz" checksum: "md5=acdf188400f2078d4210f6547b738bd1" }

Dry install with the current Coq version:
opam install -y --show-action coq-rational.8.5.0 coq.dev
[NOTE] Package coq is already installed (current version is dev). The following dependencies couldn't be met: - coq-rational -> coq < 8.6~ -> 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:
opam remove -y coq; opam install -y --show-action --unlock-base coq-rational.8.5.0
