- Coq
- Our fork of the Hahn library
- HahnExt library
- The Coq supplementary library w/ basic data types To check precise requirements with version numbers, please, check the Nix configuration file.
First, you need to install Nix (see https://nixos.org/download.html) and set-up Nix as recommended by Coq Nix Toolbox. That is, run
nix-env -iA nixpkgs.cachix && cachix use coq && cachix use coq-community && cachix use math-comp
in order to use binary caches from recognized organizations. Additionally, we recommend add our binary cache with IMM and related packages as well:
cachix use weakmemory
Then, you may just run nix-build in the root folder of the project to build it.
Alternatively, you may run nix-shell and then, in the Nix-configured environment, run make -j.
You may use the Nix Environment Selector plugin in VS Code for it to use proper configuration.
Alternatively,
you may run nix-shell in the root of the project and then code .--VSCoq or CoqLSP should be able to pick up the environment.
To build the project, one needs to install libraries (promising-lib, hahn, hahnExt), which the project
depends on.
This might be done by running ./configure.
The command installs Coq as well. After that, one needs to run make (or make -j4 for a faster build).
The project may be built and installed via OPAM:
opam repo add coq-released https://coq.inria.fr/opam/released
opam remote add coq-promising-local -k git https://github.com/snu-sf/promising-opam-coq-archive
opam remote add coq-weakmemory-local -k git https://github.com/weakmemory/local-coq-opam-archive
opam install coq-imm-
