| 2025-09-07 00:04:20 +0200 | <alienmind> | hi. i'm trying to install rasterific but can't because i'm getting missing file errors. 'ghc-pkg check' reveals a lot of packages missing 'haddock-html' and 'haddock-interfaces' files. these files seem to be missing in packages installed by pacman. i tried deleteing '~/.cabal' and running 'cabal install --reinstall Rasterific', however it results in the same missing file error. how might i proceed? |

| 2025-09-07 00:28:25 +0200 | <tomsmeding> | alienmind: assuming you're on arch linux: either install ghc-static and hope for the best, or uninstall ghc from pacman and get haskell stuff from ghcup instead |

| 2025-09-07 00:32:33 +0200 | <tomsmeding> | if you still have missing files issues with ghcup, tell us precisely what errors you get when running which commands (use e.g. the pastebin in the topic) |
| 2025-09-07 00:32:54 +0200 | <tomsmeding> | I'll be sleeping for ~9 hours now but others might pick it up :) |
| 2025-09-07 00:33:33 +0200 | <geekosaur> | right, you are most likely missing the static packages that Arch deliberately removes and which will prevent pretty much anything they don't package from installing |
| 2025-09-07 00:33:53 +0200 | <geekosaur> | as tomsmeding said, the only real fix is to ditch Arch's ghc entirely and use ghcup |

| 2025-09-07 01:26:37 +0200 | <geekosaur> | what version of cabal did you install? the LSP uses cabal to find out what ghc version a project uses, but the latest HLS doesn't work with the latest cabal (this will be fixed in the next cabal release, scheduled for when ghc 9.14.1 comes out because some tweaks were needed for that as well) |
| 2025-09-07 01:27:05 +0200 | <slondr> | I just accepted all of the default suggestions |
| 2025-09-07 01:27:11 +0200 | <slondr> | So maybe that is the problem? |
| 2025-09-07 01:27:13 +0200 | <geekosaur> | okay, then that's not it |
| 2025-09-07 01:29:57 +0200 | <geekosaur> | the default cabal version in ghcup is 3.12.1.0, it's 3.16.0.0 that breaks current HLS. (which won't be updated for it until ghc 9.14.1 is released and HLS can be updated to support its ghc-lib) |
| 2025-09-07 01:30:46 +0200 | <slondr> | yes my cabal version is 3.12.1.0 and my hls version is 9.4.8 |

| 2025-09-07 01:31:30 +0200 | <geekosaur> | HLS versions don't go that high |
| 2025-09-07 01:32:18 +0200 | <geekosaur> | also that sounds like an out of date ghcup, or at least ghcup metadata; current metadata has 9.6.7 as recommended |
| 2025-09-07 01:32:51 +0200 | <slondr> | oh! that's a clue |
| 2025-09-07 01:33:02 +0200 | <slondr> | my hls binary is named "haskell-language-server-9.4.8" |
| 2025-09-07 01:33:38 +0200 | <slondr> | It looks like I also have haskell-language-server-9.6.7 |
| 2025-09-07 01:36:16 +0200 | <slondr> | emacs lsp reports: ghc 9.6.7, cabal 3.12.1.0, stack 3.3.1 |
| 2025-09-07 01:36:48 +0200 | <slondr> | I also see: libc.so.6: undefined symbol: __nptl_change_stack_perm, version GLIBC_PRIVATE |
| 2025-09-07 01:39:01 +0200 | <geekosaur> | right, you need an HLS binary for each ghc version because the ghc-api it uses must match |
| 2025-09-07 01:39:16 +0200 | <geekosaur> | the undefined symbol one sounds like much more of a problem |

| 2025-09-07 01:52:00 +0200 | <slondr> | wait wait wait wait. the glibc error seems to be referencing a glibc version installed by nix |
| 2025-09-07 01:52:25 +0200 | <slondr> | which seems almost certainly wrong, I'd want ghc to reference the system glibc not some random nix derivation glibc |

| 2025-09-07 01:53:43 +0200 | <geekosaur> | nix really wants to be hermetic, but that can break things pretty thoroughly when it comes to stuff like glibc |
| 2025-09-07 01:54:42 +0200 | <slondr> | I don't want ghc to reference anything nix-related at all |
| 2025-09-07 01:54:47 +0200 | <slondr> | I'm not sure why it does |
| 2025-09-07 01:55:42 +0200 | <geekosaur> | make sure nix isn't substituting its own ghc for the one you intended to use |
| 2025-09-07 01:55:56 +0200 | <geekosaur> | the ghc from ghcup won't know about nix |
| 2025-09-07 01:56:16 +0200 | <slondr> | 'which ghc' reports: $HOME/.ghcup/bin/ghc |

| 2025-09-07 01:57:07 +0200 | <slondr> | though 'echo $PATH' sure does report that the /nix bin directories are above the ghcup bin directories, hmm |
| 2025-09-07 01:57:44 +0200 | <geekosaur> | shells cache paths, but something run in a subshell or by a program you run from that shell won;t see the cache and will find the nix one first in that case |
| 2025-09-07 01:59:54 +0200 | <geekosaur> | that said, nix wouldn't insert a ghc into your path unless you're in a directorry with a shell.nix and something knows enough about nix to see that file and load the derivations it specifies |
