 twz123 | > to avoid bootstrapping
Does anybody have a RISC-V binary cache somewhere? I'm not even able to get cachix compiled. AFAICT GHC can't be bootstrapped on riscv64 and cross compiling doesn't work either (due to Template Haskell stuff not being able to be cross compiled). Only idea that I have currently is to copy the store paths over to other machines on which cachix is available. | 15:28:19 |

Only idea that I have currently is to copy the store paths over to other machines on which cachix is available. GHC can be bootstrapped, but it's not yet in Nixpkgs haskell-updates.
https://github.com/NixOS/nixpkgs/pull/243619
(Note that there is also an unrelated bug with cross-compiling {cc,binutils}-wrapper that you'll want to fix before building. See first comment.)
As for existing binary caches, there are a few, e.g. https://github.com/misuzu/nixos-vf2/blob/master/flake.nix#L3
Even then, I doubt you'll find much beyond the absolutely necessary tools in these caches. | 15:32:45 |
| Alex | Be warned that TH is completely broken on RISC-V in general because GHC has to be built unregistered (see https://gitlab.haskell.org/ghc/ghc/-/issues/23957), and Nixpkgs doesn't have anything in place to make TH work in cross/unregisterised scenarios.
Most Haskell packages can still be built by disabling test suites (when they depend on TH) and overriding Cabal files (when the package uses a multithreaded-only RTS flag). | 15:35:53 |

Even then, I doubt you'll find much beyond the absolutely necessary tools in these caches. Thanks. You mean that when trying out the aforementioned PR, I might be able to get GHC compiled? Will try that out. I don't have any idea about Haskell whatsoever, so I'd probably not be able to override anything in the Cabal files. (I can override stuff with doCheck=false though and see if that gets me anywhere 😄). I'll check out cache.ztier.in. It'd already help if only stdenv would be in there. Bootstrapping gcc is no fun 😵💫. Do you know who maintains that cache? | 15:49:37 |
