• https://downloads.haskell.org/~ghc/9.8.2/ghc-9.8.2-aarch64-alpine3_18-linux.tar.xz

TODO:

• build ghcup binary
• build cabal binary
• build HLS binaries (when supported)

Just another note (but no pressure or expectation). I have added support to GHC's bindist testing for aarch64 alpine which is just waiting for ghcup binaries to be available.

We're in luck, there is a cabal-install in the alpine repos, so bootstrapping should be easier: https://pkgs.alpinelinux.org/package/edge/community/aarch64/cabal

Hi, I was wondering what work remains to be done or what blockers remain for this. Is it the same as what's listed in the initial issue? Depending on the nature/extent of the work I may be able to contribute some time to it.

All points remain. Cabal needs bootstrapping.

This is mostly done now. The only thing that's missing is adjusting release CI:

• https://github.com/haskell/ghcup-hs/blob/master/.github/workflows/release.yaml
• https://github.com/stable-haskell/cabal/blob/cabal-install-v3.12.1.0/.github/workflows/release.yaml
