Haskell extension can't figure out LLVM version on macOS

[stefanscheidt]

Your environment

Which OS do you use:

macOS 12.5 (21G72) on Apple Silicon M1

Steps to reproduce

Create simple "hello-cabal" project as described here, open VS Code with Haskell Extension from terminal via code ., opening Main.hs in VSCode

Expected behaviour

HLS should work.

Actual behaviour

HLS Extension shows a problem:

Until then, a got Couldn't figure out LLVM version! in the Terminal, too

Include debug information

Execute in the root of your project the command haskell-language-server-wrapper --debug . and paste the logs here (you can find the executable location here):

[stefanscheidt]

The issues does not occur when using GHC 9.2.2 instead of GHC 8.10.7.

[fendor]

Hi! Thank you for the bug report.

Is this specific to the haskell extension? E.g. can build your project with cabal and ghc-8.10.7 in the terminal?

Very curious, the PATH seems to be correct, and the cli invocation succeeds...

Ok, I am theory crafting right now, maybe the location of opt is determined from the location of GHC (which is something we override) passed to cabal for 8.10.7? I can try to reproduce, locally.

[stefanscheidt]

First: Thanks for the super quick response!
Second: Just to make sure: It works on the command line when adding /opt/homebrew/opt/llvm@12/bin to the PATH, which I did in .zshrc. I opened the project in VS Code via code .. As a maybe irrelevant info: on Intel hardware, homebrew stuff resides in /usr/local, if this makes any difference.

When using GHC 9.2.2, everything (cabal build and cabal run) works fine (as far as I can see) on the command line and in VS Code even without adding /opt/homebrew/opt/llvm@12/bin to the PATH.

FYI: I'm a total beginner in Haskell and the whole tooling stuff (ghcup, ghc, ghci, hls, cabal, stack) and my experience is only based on GHCUp First steps, thus I may not be able to provide deeper info. I was using GHC 8.10.7 instead of 9.2.2 as it was listed as recommended by ghcup.

[fendor]

Your information is quite thorough, thank you very much!

Ah, interesting, the PATH variable shown in the vscode extension output looks like this:

/Users/stefanscheidt/.ghcup/tmp/ghcup-ghc-8.10.7_cabal-3.6.2.0_hls-1.7.0.0_stack-2.7.5
/opt/homebrew/opt/llvm@12/bin
/Users/stefanscheidt/.local/bin
/Users/stefanscheidt/local/bin
/usr/local/bin
/usr/local/sbin
/Users/stefanscheidt/.sdkman/candidates/scalacli/current/bin
/Users/stefanscheidt/.sdkman/candidates/sbt/current/bin
/Users/stefanscheidt/.sdkman/candidates/maven/current/bin
/Users/stefanscheidt/.sdkman/candidates/kotlin/current/bin
/Users/stefanscheidt/.sdkman/candidates/java/current/bin
/Users/stefanscheidt/.sdkman/candidates/gradle/current/bin
/Users/stefanscheidt/.pyenv/shims
/Users/stefanscheidt/.pyenv/bin
/Users/stefanscheidt/.cabal/bin
/Users/stefanscheidt/.ghcup/bin
/opt/homebrew/opt/llvm@12/bin
/opt/homebrew/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/bin
/opt/homebrew/bin
/opt/homebrew/sbin
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
/Users/stefanscheidt/.cargo/bin

so the PATH /opt/llvm@12/bin seems to be missing.

Maybe you can fix it by adding that path to your PATH variable? Like here: https://github.com/haskell/vscode-haskell#stackcabalghc-can-not-be-found

{
  "haskell.serverEnvironment": {
    "PATH": "/opt/llvm@12/bin:$PATH"
  }
}

You can modify the serverEnvironment by opening settings > Haskell > serverEnvironment.

[stefanscheidt]

Hi. Sorry, but there is no path /opt/llvm@12/bin. llvm ver. 12 is installed to /opt/homebrew/opt/llvm@12, and /opt/homebrew/opt/llvm@12/bin is on the path.

By the way I already tried to add /opt/homebrew/opt/llvm@12 to the server environment path explicitly with no success.

Ah, I just misread the path you showed, because it line-breaks on my screen in an unfortunate way. Ok, then you will have to wait for me to reproduce it, no idea what is going wrong :)

OK. Thank you so much for your effort!

PATH="/opt/homebrew/Cellar/llvm@12/12.0.1_1/bin:$PATH"

… did it for me :-D

Hello, I met this question too, and I solved it.
For some reasons I switch to ghc 8.10.x and I have checked that I installed llvm@12 by command brew list, and I export PATH to the .zshrc , but ghc still throw error.

Eventually, I found this discussion did work, adding -fllvm to ghc-option succeed.
