In the plane: Two axiom systems are shown equivalent. We prove some results about the decidability of the the incidence and equality predicates. The classic notion of duality between points and lines is formalized thanks to a functor. The notion of 'flat' is defined and flats are characterized. Fano's plane, the smallest projective plane is defined. We show that Fano's plane is desarguesian. In the space: We prove Desargues' theorem.""" flags: light-uninstall url { src: "https://github.com/coq-contribs/projective-geometry/archive/v8.8.0.tar.gz" checksum: "md5=628607751d60d2b4db643e5c82329c9e" }

Dry install with the current Coq version:

- Command
`opam install -y --show-action coq-projective-geometry.8.8.0 coq.dev`

- Return code
- 5120
- Output
[NOTE] Package coq is already installed (current version is dev). The following dependencies couldn't be met: - coq-projective-geometry -> coq < 8.9~ -> ocaml < 4.05.0 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-projective-geometry.8.8.0`
