Cabal: Bindist for ARM

Created on 18 Apr 2020  路  7Comments  路  Source: haskell/cabal

There are no bindists for ARM. This is currently blocking ghcup support for the raspberry pi and other ARM devices: https://gitlab.haskell.org/haskell/ghcup-hs/issues/12#note_266006.

See https://downloads.haskell.org/~cabal/cabal-install-3.2.0.0/.

What needs to be done to get bindists for ARM?

I'd prefer that this is resolved via https://github.com/haskell/cabal/issues/6616 and not so various people provide bindists (in pretty opaque way). The assembly of bindists should be scripted with scripts perfectly living in this repository.

I'd need to figure out on which machine those arm7 bindists of GHC were built on (ping @bgamari?) and whether I can get access there to build cabal binaries accordingly.

Same for aarch64 btw

Note my comment on #6616. Based on my this week experiences, if ARM is not a platform which "just works", we (= regular Cabal contributors) won't have resources to maintain it.

I feel this is a little awkward zic-zac. We made @samuela do extensive work on the cabal CI, although he was merely interested in ARM bindists. Now we're telling him ARM won't be supported? There surely is a better way to handle this:

  1. include it in the CI
  2. make sure users understand it is experimental
  3. ask people for help on ARM, if bindists don't work. Apparently, there's at least a couple who care.

Ok, it's official... Apple is switching to ARM! So getting ARM builds working one way or another will be necessary.

@samuela if you manage to make such bindists manually, then they can be used by ghcup as well. We're not constrained to upstream bindists.

I am having trouble bootstrapping 3.4.0.0-rc1 on arm64/v8 with GHC 8.10.2 and LLVM 9. Everything works fine on amd64 with exactly the same code, but not on arm64/v8.
I used the following boostrap json config:
