1 year ago Thanks for the issue! I got a new Apple M1 laptop recently, ran into all the build issues mentioned above.
After a day of debugging, I'm close to getting Dex to build on Apple M1:
- LLVM 15:
brew install llvm@15and https://github.com/llvm-hs/llvm-hs/tree/llvm-15 resolver: lts-20.15(GHC 9.2.7) instack-macos.yaml
Current status: upgrading to GHC 9.2.7 has resulted in some dex-lang compilation errors, probably due to language changes:
```
$ make
stack --stack-yaml=stack-macos.yaml build --ghc-options="-j +RTS -A256m -n2m -RTS" --extra-include-dirs=/opt/homebrew/include --extra-lib-dirs=/opt/homebrew/lib --fast
...

I'll plan to follow-up here within a week. If the final fixes aren't too tricky, I should be able to share a pull request with instructions.
Just wanted to leave a few notes on building the project on an M1 Mac (aarch64) should you decide to support the architecture in the future:
ghcupto download a Stack that builds for the appropriate architecture (required for llvm-hs)/opt/homebrew/includeso it requires an additional wildcard check in makelts-18.23for M1, (see here) - I tried upgrading to a later version of GHC but I don't know enough about this project or Haskell build in general to fix the dependency chainsJust posting this in case it helps someone else or I missed something, as I would like to return to the project and look for possible contributions once it is working.
