The build uses [Stack](http://docs.haskellstack.org/). If you don't already have it installed, [follow the install instructions](http://docs.haskellstack.org/en/stable/README.html#how-to-install) for your platform. (Hint: `brew update && brew install stack`)

# M1 Mac Haskell toolchain setup
|
||||
|
||||
If you are a newcomer to the Haskell ecosystem trying to set up your dev environment on a Mac M1 computer, welcome, you can do this! The tips in this document provide one way to get a working development setup, but are not the only path forward. If you haven't downloaded the Haskell toolchain before, our recommendation is to use GHCup. We've found that issues can arise if you mix ARM native binaries with x86 binaries to be run with Rosetta. If you're a veteran Haskell developer, much of this won't apply to you as it's likely you already have a working development environment.
|
||||
|
||||
Here is a working set of versions you can use to build the Unison executable:
|
||||
|
||||
- GHC version: 8.10.7
|
||||
- Stack version: 2.9.1
|
||||
- Cabal version 3.6.2.0
|
||||
- Haskell language server version: 1.7.0.0
|
||||
|
||||
The GHC version for the project can be confirmed by looking at the `resolver` key in this project's `stack.yaml`.
|
||||
|
||||
## Newcomer setup tips
|
||||
|
||||
[Install GHCup using the instructions on their website.](https://www.haskell.org/ghcup/) Once it's installed make sure `ghcup` is on your path.
|
||||
|
||||
```
|
||||
export PATH="$HOME/.ghcup/bin:$PATH"
|
||||
```
|
||||
|
||||
GHCup has a nice ui for setting Haskell toolchain versions for the project. Enter `ghcup tui` to open it up and follow the instructions for installing and setting the versions there. GHCup will try to download M1 native binaries for the versions given.
|
||||
|
||||
Check your clang version. For [hand-wavey reasons](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/301) we recommend you use llvm version 12. See troubleshooting note below about changing your LLVM if your version is different.
|
||||
|
||||
```shell
|
||||
$ clang --version
|
||||
Homebrew clang version 12.0.1
|
||||
Target: arm64-apple-darwin20.2.0
|
||||
Thread model: posix
|
||||
InstalledDir: /opt/homebrew/opt/llvm@12/bin
|
||||
```
|
||||
|
||||
At the end of the process you should see something like the following for executable locations and versions.
|
||||
|
||||
```shell
|
||||
$ which ghcup
|
||||
~/.ghcup/bin/ghcup
|
||||
$ ghcup --version
|
||||
The GHCup Haskell installer, version 0.1.19.0
|
||||
```
|
||||
|
||||
```bash
|
||||
$ which stack
|
||||
~/.ghcup/bin/stack
|
||||
$ stack --version
|
||||
Version 2.9.1, Git revision 13c9c8772a6dce093dbeacc08bb5877bdb6cfc2e (dirty) (155 commits) aarch64
|
||||
```
|
||||
|
||||
```shell
|
||||
$ which ghc
|
||||
~/.ghcup/bin/ghc
|
||||
$ ghc --version
|
||||
The Glorious Glasgow Haskell Compilation System, version 8.10.7
|
||||
```
|
||||
|
||||
Check which GHC version Stack thinks it's using too, for good measure:
|
||||
|
||||
```shell
|
||||
$ stack ghc -- --version
|
||||
The Glorious Glasgow Haskell Compilation System, version 8.10.7
|
||||
$ stack exec -- which ghc
|
||||
~/.ghcup/ghc/8.10.7/bin/ghc
|
||||
```
|
||||
|
||||
```shell
|
||||
$ which haskell-language-server-wrapper
|
||||
~/.ghcup/bin/haskell-language-server-wrapper
|
||||
$ haskell-language-server-wrapper
|
||||
|
||||
Found "...unison/hie.yaml" for "...unison/a"
|
||||
Run entered for haskell-language-server-wrapper(haskell-language-server-wrapper) Version 1.7.0.0 aarch64 ghc-9.2.2
|
||||
Current directory: ...unison
|
||||
Operating system: darwin
|
||||
Arguments: []
|
||||
Cradle directory: ...unison
|
||||
Cradle type: Stack
|
||||
|
||||
Tool versions found on the $PATH
|
||||
cabal: 3.6.2.0
|
||||
stack: 2.9.1
|
||||
ghc: 8.10.7
|
||||
```
|
||||
|
||||
If you're a VS Code user, you can download the Haskell extension for IDE support. You may need to configure it in `settings.json`.
|
||||
|
||||
```json
|
||||
"haskell.manageHLS": "GHCup",
|
||||
"haskell.toolchain": {
|
||||
"stack": "2.9.1",
|
||||
"ghc": "8.10.7",
|
||||
"cabal": "recommended",
|
||||
"hls": "1.7.0.0"
|
||||
}
|
||||
```
|
||||
|
||||
These setting blocks say that the VS Code extension will use GHCup for your Haskell language server distribution, and sets the versions for elements in the toolchain.
|
||||
|
||||
## Troubleshooting:
|
||||
|
||||
The VS Code extension has compiled a helpful list of troubleshooting steps here: https://github.com/haskell/vscode-haskell#troubleshooting
|
||||
|
||||
### "Couldn't figure out LLVM version" or "failed to compile a sanity check" errors
|
||||
|
||||
```
|
||||
<no location info>: error:
|
||||
Warning: Couldn't figure out LLVM version!
|
||||
Make sure you have installed LLVM between [9 and 13)
|
||||
ghc: could not execute: opt
|
||||
```
|
||||
|
||||
Or
|
||||
|
||||
```
|
||||
ld: symbol(s) not found for architecture x86_64
|
||||
clang: error: linker command failed with exit code 1 (use -v to see invocation)
|
||||
`gcc' failed in phase `Linker'. (Exit code: 1)
|
||||
```
|
||||
|
||||
Try installing llvm version 12
|
||||
`brew install llvm@12`
|
||||
|
||||
and prepend it to your path
|
||||
```
|
||||
export PATH="$(brew --prefix)/opt/llvm@12/bin:$PATH"
|
||||
```
|
||||
|
||||
(The GHC version 8.10.7 mentions it supports LLVM versions up to 12. https://www.haskell.org/ghc/download_ghc_8_10_7.html)
|
||||
|
||||
### "GHC ABIs don't match!"
|
||||
|
||||
Follow the steps here:
|
||||
|
||||
https://github.com/haskell/vscode-haskell#ghc-abis-dont-match
|
||||
|
||||
We found some success telling Stack to use the system's GHC instead of managing its own version of GHC. You can try this by setting the following two configuration flags in ~/.stack/config.yaml
|
||||
|
||||
```
|
||||
system-ghc: true
|
||||
install-ghc: false
|
||||
```
|
||||
|
||||
This is telling Stack to use the GHC executable that it finds on your $PATH. Make sure the ghc being provided is the proper version, 8.10.7, from ghcup.
|
||||
|
||||
Note that you may need to clean the cache for the project after this failure with `stack clean --full` if you have previously built things with a different stack distribution.
|
||||
|
||||
### "stack" commands like "stack build" cause a segfault:
|
||||
|
||||
1. Make sure your stack state is clean. `stack clean --full` removes the project's stack work directories (things in .stack-work).
|
||||
2. [Wait for this bug to be fixed (or help fix this bug!)](https://github.com/commercialhaskell/stack/issues/5607)
|
||||
3. Or subshell out your stack commands `$(stack commandHere)`
|
||||
4. Or use bash instead of zsh
|
||||
|
||||
### Help! Everything is broken and I want to start over
|
||||
|
||||
Warning, the following will remove ghcup, configuration files, cached packages, and versions of the toolchain.
|
||||
|
||||
```
|
||||
ghcup nuke
|
||||
rm -rf ~/.ghcup
|
||||
rm -rf ~/.stack
|
||||
rm -rf ~/.cabal
|
||||
```
