I have a project I normally build with nix and cabal, however I also want to publish my documentation onto gitlab pages. It's impractical to run my nix on the gitlab CI, so I've just been using cabal. Here was my .gitlab-ci.yaml:
default:
image: haskell:9
stages:
- pages
pages:
stage: pages
artifacts:
paths:
- public
script:
- cabal v2-haddock --builddir=out
- mv ./out/build/*/ghc-*/*-*/doc/html/*/ ./public
And here's my package.yaml:
name: lib
version: 0.1.1.0
license: AGPL
author: Me
copyright: 2024 Me
extra-source-files:
- README.md
dependencies:
- base >= 4.14 && < 5
- containers >= 0.6.5 && < 0.7
library:
source-dirs:
src
This worked until I needed to use text-icu. I added text-icu to my nix and package.yaml:
dependencies:
- base >= 4.14 && < 5
- containers >= 0.6.5 && < 0.7
+ - text
+ - text-icu >= 0.7 && < 0.9
And this works on my local machine just fine. But I can't use my nix on gitlab CI and gitlab's docker image doesn't have text-icu. So I get an error:
Error: cabal: Could not resolve dependencies:
[__0] trying: lib-0.1.1.0 (user goal)
[__1] unknown package: text-icu (dependency of lib)
[__1] fail (backjumping, conflict set: lib, text-icu)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: lib, text-icu
I'm really used to using nix, so I'm not sure how to fix this. I tried a couple of random things in hope they would solve the issue by chance, but they didn't and I don't have any informed ideas. How can I supply this dependency to the gitlab-ci so that cabal can access it?
If cabal doesn't find text-icu, it's probably because the local package index is empty. You can update it with cabal update.
script:
- cabal update
- cabal haddock ...
