I confirm that this approach does not work on an M1 Mac. Trying to install a stack portion an M1—whether or not `supported_archs x86_64` is set—throws this architecture mismatch error when trying to install on the M1: > Cannot install shellcheck for the arch 'arm64' because > It’s dependency

Re: Haskell Stack Ports on Apple Silicon

Wouldn’t the best solution be to combine Ken’s two good ideas from this thread and add `supported_archs x86_64` to the haskell_stack portgroup, which would handle all ports built using stack? > IF pandoc set it’s supported_archs to x86_64 (which then matches stack) — > would that now install

Re: Haskell Stack Ports on Apple Silicon

I don't think it's overly simple to guess what might actually happen, or work. You have to try it various ways, and as Ryan says, I guess also try it when pandoc is pulled in as a dependency rather than directly installed, and see. The automatic fallback to other supported arches (eg arm64 ->

Re: Haskell Stack Ports on Apple Silicon

If the Macports-compiled stack runs on arm64, then the prebuilt download will too. The issue as far as I can tell from the internet is that stack will generate x86_64 binaries, even if running on an M1. https://www.haskell.org/ghc/blog/20200515-ghc-on-arm.html These x86_64 binaries should run

That line is indeed limiting support to intel machines. If it works on arm add that to the list, or probably better just remove it and rely on the defaults. Chris > On 13 Aug 2021, at 1:55 pm, Steven Smith wrote: > > Is this line in the stack Portfile the issue? Ports (like pandoc) that are

Haskell Stack Ports on Apple Silicon

I have an M1 box on which I’d like to install some haskell ports. The good news: `sudo port install stack` works and the binary runs on an M1. But when I try to install, e.g., pandoc, I hit this architecture mismatch error: > Cannot install pandoc for the arch 'arm64' because > It’s dependency
