Contents of hie.yaml:

cradle:
  cabal:
    - path: "./src"
      component: "lib:plutus-proj01"

Steps to reproduce

Open any file in Atom e.g.
https://github.com/tdiesler/plutus-pioneer-program/blob/mystuff/code/proj01/src/Proj01/Counter1.hs

Actual behaviour

Atom repeatedly reports haskell-language-server crash - then gives up.

Include debug information

Execute in the root of your project the command haskell-language-server --debug . and paste the logs here:

Hi, thanks for the nice bug report.
If you run directly the command reported (/Users/tdiesler/.ghcup/bin/haskell-language-server-8.10.4 "--debug") in the cli, does it gives more details (in addition to the returned error code -11) about the error?

For completeness, when you use "keeps" do you want to mean that previous versions of hls has been failing in the past?

tdiesler · 2021-05-20T10:49:08Z

Here you go ...

$ /Users/tdiesler/.ghcup/bin/haskell-language-server-8.10.4 "--debug" 2> hls-crash-debug.txt
Segmentation fault: 11

hls-crash-debug.txt

At first, it worked great and I learned a lot from the linting hints. Lately however, hls keeps crashing and I see a lot of annoying popups and no more useful hints. I installed my Haskell env with ghcup.

hls keeps crashing

Atom makes repeated attempts to run HLS - they crash repeatedly - then Atom gives up.

I may be facing a similar problem. I am running macOS 11.3.1. For the first few lessons, the HLS works well, but from lesson 4 onward HLS attempts to run 3-4 times, and it stops with the error message

[coc.nvim] The "languageserver.haskell" server crashed 5 times in the last 3 minutes. The server will not be restarted.

isovector · 2021-05-25T06:35:12Z

@hududed the segmentation fault suggests it's not HLS' fault; it's extremely hard to get Haskell to cause a segfault.

pepeiborra · 2021-06-08T11:41:31Z

There is a simple workaround as you have found: use Linux. If you are stuck with Mac OS, try building HLS locally using --enable-executable-dynamic, more details in #469

tdiesler · 2021-06-18T16:38:00Z

I built hls-1.2.0 on MacOS like this ...

./cabal-hls-install --enable-executable-dynamic hls-8.10.4

... and unfortunately got the same error.

fendor · 2021-06-18T17:08:05Z

 ./cabal-hls-install --enable-executable-dynamic hls-8.10.4

The installation script doesn't support such arguments. It should work if you invoke cabal configure --enable-executable-dynamic && ./cabal-hls-install hls-8.10.4

tdiesler · 2021-06-18T17:29:26Z

Thanks, but same error unfortunately.

quangIO · 2021-06-19T04:19:17Z

The workaround fixes the issue for me. I add the line executable-dynamic: True to ~/.cabal/config, then run

cabal clean # just to be sure
cabal build exe:haskell-language-server-wrapper
cabal install exe:haskell-language-server-wrapper --overwrite-policy=always

tdiesler · 2021-06-19T10:11:47Z

Lovely, that works - Merci

jneira · 2021-06-19T18:48:52Z

Afaik cabal should honour --enable-executable-dynamic and it shouls have the same effect than change the global config.
I've not found any issue in the cabal project about.

korayal · 2021-06-21T22:43:48Z

We've been having this same issue on our macOS environment, and I can confirm that --enable-executable-dynamic fixes the problem. I was able to build HLS HEAD on nix with this flag enabled here (FYI, I heavily suggest using the cachix cache mentioned in the repository, otherwise it takes forever to build) for GHC 8.10.4, and I do not get my LSP server terminated any more.

jneira · 2021-06-22T05:52:58Z

Afaik cabal should honour --enable-executable-dynamic and it shouls have the same effect than change the global config.
I've not found any issue in the cabal project about.

Maybe the problem is cabal configure --enable-executable-dynamic which writes the option to cabal.project.local. The updated/created cabal.project.local should be the placed in the root of the project and no inside ./install. So if you run the command inside ./install it will not work for hls but for the install program itself.
@tdiesler maybe that was the cause it did not work for you?

franleplant · 2021-07-06T00:58:40Z

The workaround fixes the issue for me. I add the line executable-dynamic: True to ~/.cabal/config, then run
cabal clean # just to be sure
cabal build exe:haskell-language-server-wrapper
cabal install exe:haskell-language-server-wrapper --overwrite-policy=always

I got this when trying to use this solution

HEAD is now at a761044 HasContextEntry

a syntax that's sufficiently qualified to give an unambiguous match. However

jneira · 2022-01-31T12:06:27Z

I am gonna close this issue as all compiler crashes seems to have the same root cause:

We have a general issue about: Improve template haskell support (upstream fix and workaround for compiler crashes) #1431
And other one with more info about the causes: Document why hls binaries are statically linked (and track ghc changes to allow loading dynamic libs within a static executable) #2000
We have a generic workaround (build hls from source dynamically linked) documented in the troubleshooting guide: https://haskell-language-server.readthedocs.io/en/latest/troubleshooting.html#static-binaries-and-template-haskell-support
And a possible fix upstream for ghc described in Document why hls binaries are statically linked (and track ghc changes to allow loading dynamic libs within a static executable) #2000 (comment)

If any of you think the issue should not be included generically feel free to reopen it (with a brief explanation if possible)
Thanks all!
