cd compiler
nix-shell -p cabal2nix

cabal build --minimize-conflict-set --allow-newer=base --ghc-options=-dynamic seems to be a simpler solution to the dependency problem, however this is only tested for the worker build.

Working with compiler too.

I was wondering if you had succeeded at building elm on M1 more recently than March. Also, what versions of ghc/cabal are you using, and did you have to install other dependencies?

$ cabal --version
cabal-install version 3.6.2.0

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.10.7

I have llvm@12 installed via homebrew.

When I run cabal, it errors with this message:

[136 of 136] Compiling Crypto.Tutorial  ( Crypto/Tutorial.hs, dist/build/Crypto/Tutorial.o, dist/build/Crypto/Tutorial.dyn_o )

<no location info>: error:
    Error running clang! you need clang installed to use the LLVM backend
    (or GHC tried to execute clang incorrectly)
`clang' failed in phase `Clang (Assembler)'. (Exit code: 1)
cabal: Failed to build cryptonite-0.30 (which is required by exe:elm from
elm-0.19.1). See the build log above for details.

When I try with a newer version of ghc (installed via ghcup) it gives other errors much further up the dependency chain, which is why I'm trying an older tool chain.

Ok, I switched to llvm@13 and cabal build -O2 seems to be working.

Thanks for sharing this info. I went to just installing elm through npm.
