Defines Lebesgue integral and associated concepts such as measurability, measure functions, and sigma algebras. Extended real numbers did not need to be defined because we are working in a probability space with measure 1. Nonconstructive; uses classic, Extensionality_Ensembles, axiomatized real numbers from Coq standard library." flags: light-uninstall url { src: "https://github.com/coq-contribs/markov/archive/v8.7.0.tar.gz" checksum: "md5=562f69118aadd4091485ae6698f2e582" }

Dry install with the current Coq version:
opam install -y --show-action coq-markov.8.7.0 coq.8.11.0
[NOTE] Package coq is already installed (current version is 8.11.0). The following dependencies couldn't be met: - coq-markov -> coq < 8.8~ -> 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-markov.8.7.0
