 alexfmpe | I dunno about flakes, but nix-build -A haskellPackages.smtlib-backends-z3 on nixpkgs master works just fine on my macos | 15:04:23 |
| alexfmpe | where hackage-packages.nix shows z3 on librarySystemDepends of smtlib-backends-z3 | 15:05:11 |
| alexfmpe | ah, same for haskellPackages.z3 | 15:06:27 |
| alexfmpe | huh, isn't packages for executables only? | 15:07:47 |

| alexfmpe | try inputsFrom | 15:08:04 |
 VegOwOtenks | Thanks! I will try inputsFrom, I don't have any clue about the differences. | 15:12:54 |
| alexfmpe | my link should explain it | 15:15:50 |
| alexfmpe | * my link above explains them | 15:15:59 |
| alexfmpe | you probably want the same for libllvm and libclang | 15:17:55 |
| alexfmpe | can we improve the whole security_tool issue for mac builds?
https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/haskell-modules/configuration-darwin.nix is littered with
dontCheck that, well, makes us not run testssubstituteInPlace System/X509/MacOS.hs --replace-fail security /usr/bin/security that breaks sandbox builds
I also run into it for some packages on darwin pkgsStatic builds somehow due to the iserv-proxy thing

| alexfmpe | huh, wait, maybe that's not the same "security" ? hard to tell with case insensitive system | 16:47:08 |

that looks like the internal linker trying to load the Security framework, but I don’t think that’s available as a static archive, so won’t work at all in pkgsStatic?! | 07:30:00 |
 tks_123 | Hi all | 16:39:50 |
| tks_123 | Redacted or Malformed Event | 16:40:28 |
| tks_123 | I have this flake.nix: https://pastebox.io/api/paste/3WT3DwMK6KZz | 16:41:56 |
| tks_123 | After doing "nix develop" from top-level dir (same dir as flake.nix dir), I can successfully "cd" into each of the subdirectories, to run "cabal build" on those two individual Haskell projects. | 16:42:58 |
| tks_123 | * After doing "nix develop" from top-level dir (same dir as flake.nix dir), I can - if the second project doesn't try to depend on the first project - successfully "cd" into each of the subdirectories, to run "cabal build" on those two individual Haskell projects. | 16:43:36 |
| tks_123 | However, if I add "my-haskell-library" (the first project) into the build-depends of the second project, doing "cabal build" on the second project fails, complaining that "my-haskell-library" is not found. | 16:44:27 |
| tks_123 | What am I doing wrong? | 16:44:29 |
| tks_123 | * However, if I add "my-haskell-library" (the first project) into the build-depends of the second project ("my-haskell-executable"), doing "cabal build" on the second project ("my-haskell-executable") fails, complaining that "my-haskell-library" is not found. | 16:45:03 |
| tks_123 | Hmm after putting this into cabal.project of the second project
packages:
.
../my-haskell-library
everything seems to work. | 16:55:44 |
| tks_123 | Why? | 16:55:49 |
| tks_123 | I thought... the haskellPkgs in Nix was supposed to tell cabal about all known Haskell packages? | 16:56:16 |
| tks_123 | So why was a cabal.project needed to make this work? | 16:56:23 |
 ijouw | I would assume you need two flakes if you want to package them individually, but i am neither very proficient in flakes nor nix so i might be mistaken. | 17:54:03 |
| alexfmpe | I think shellFor won't add `packages` to `ghc-pkg list` since you're asking for a shell for iterating on them | 19:18:29 |
| alexfmpe | So you need cabal.project to tell cabal about the other project | 19:18:56 |
