Artem	That's the liquid-fixpoint package, its "test" test suite appears to call to the "fixpoint" executable from the same package but nix-build arrives at: `... Running phase: checkPhase Running 2 test suites... Test suite test: RUNNING... /bin/sh: fixpoint: not found`	19:21:05
sterni (he/him)	Artem: you need to add the build directory to PATH before execution since Cabal won't do it for you unfortunately	19:58:37
sterni (he/him)	there should probably be a shorthand for it, but you can just grep configuration-nix.nix for PATH to see how to do it	19:58:59
sterni (he/him)	emily: Alyssa Ross: See https://nixos.org/manual/nixpkgs/unstable/#haskell-derivation-deps for input specificication in haskellPackages. Everything is eventually mapped to `buildInputs`, `propagatedBuildInputs` and `nativeBuildInputs`. Using `checkInputs` and friends is not necessary since that is basically a shorthand for adding `lib.optionals doCheck [ … ]` to `buildInputs`/`nativeBuildInputs` and we have to conditionalize loads on `doCheck` anyways.	20:02:03
