@teto you didn't answer about ~/.stack/config.yaml

does it have packages in it?

and what does stack.yaml contain?

Matthieu Coudron

@teto

~/.stack/config.yaml did contain packages. It works now

Kirill Zaborsky

@qrilka

great to hear that it was resolved

I want to staticly link a '.a' (from rust) into the binary but cant seem to get it to work. Are there any resources on this?
i have tried

    extra-libraries:
      - nameoflib
    extra-lib-dirs:
      - /locoflib/

but this only works with absolute paths, and i need a relative path as the other project is in the same repo and distributed along with it

Hey quick question

now with pantry; is there any semantic difference between putting things in a snapshot vs putting them in extra-deps in stack.yaml?

hey guys,I'm new to haskell and I'm following the turtorial of "learn haskell" try to use stack to install ghc

but there's something wrong when I try to "stack setup"

Exception while reading snapshot from lts-15.12:
HttpExceptionRequest Request {
  host                 = "raw.githubusercontent.com"
  port                 = 443
  secure               = True
  requestHeaders       = [("User-Agent","Haskell pantry package")]
  path                 = "/commercialhaskell/stackage-snapshots/master/lts/15/12.yaml"
  queryString          = ""
  method               = "GET"
  proxy                = Nothing
  rawBody              = False
  redirectCount        = 10
  responseTimeout      = ResponseTimeoutDefault

}
 (InternalException (HostCannotConnect "raw.githubusercontent.com" [Network.Socket.connect: <socket: 14>: does not exist (Connection refused),Network.Socket.connect: <socket: 14>: does not exist (Connection refused)]))

I tried to use a http_proxy but still not work

this is my environment

And because I'm a student in china I'm using the configuration mentioned in install_and_upgrade.md

Is there a way to build a benchmark binary and copy it out? i don't seem to be able to get a hold of it.

Jens Petersen

@juhpetersen_gitlab

Does stack (now?) drop a new build cache when the initial build fails?

I better check github issues

Jens Petersen

@juhpetersen_gitlab

Not sure, maybe it was a local issue or some corner case

Hey - is it possible to profile a stack 'script' ?

hi guys, I am trying to get https://github.com/haskell/haskell-language-server#features built by bazel. I can't get stack.yaml to fetch the submodules so everything fails. Here is an excerpt from my stack.yaml:

packages:
- github: haskell/haskell-language-server
  # 0.4 release
  commit: 0a18edde24923251a148cbbc0ae993a6aac83b9c
  sha256: e965019bc48ef75e43992b209055e55b245faaaede04c02fb4825f124ebc3dd1
  subdirs:
    - .
    - ./ghcide/
    - ./hls-plugin-api

Javier Neira

@jneira

hls contributor here, I think you should be able to build it moving ghcide to extra-deps, as it was uploaded to hackage

Matthieu Coudron

@teto

thanks, I found a workaround

Javier Neira

@jneira

he I be just noticed the date 🤦‍♂️

Matthieu Coudron

@teto

I am trying to run commands from https://github.com/theam/aws-lambda-haskell-runtime/blob/master/doc/06-deploying-a-lambda.md#manual-deploy but it fails with Cannot use both Docker and Nix at the same time . Wha'ts wrong with using docker from within a nix-shell ?

Matthieu Coudron

@teto

oh it's not because of the nix-shell, I can't use it anywhere (using nixos) :/

Kirill Zaborsky

@qrilka

@teto this binary choice between nix/docker was done in commercialhaskell/stack#4636 and commercialhaskell/stack#4647 - I guess those links should give you some info about the motivation

Matthieu Coudron

@teto

Kind of a follow up but I get

$ stack build --no-nix --docker
Resolver not supported for Docker images:
    no resolver specified
Use an LTS resolver, or set the 'image' explicitly, in your configuration file.

with this package.yaml (taken from https://notquiteamonad.com/blog/2021-02-15-writing-aws-lambdas-in-haskell)

# package.yaml

resolver: lts-16.31

executables:
  getSecret:
    main: Main.hs
    source-dirs: src/
    dependencies:
      - hal # This project's library
      - amazonka # This project's library
      # --snip--
    ghc-options:
      - -threaded
      - -rtsopts
      - -O2
      - -static
      - -with-rtsopts=-N
      - -Wall
    cc-options: -static
    # ld-options: -static -pthread

What strikes me is that I see 0 results on google

Matthieu Coudron

@teto

If I pass the resolver on command line it works stack build --no-nix --docker --resolver lts-16.31 :) but then I hit Cannot determine project root directory for Docker sandbox.

Matthieu Coudron

@teto

nevermind seems like stack.yml is mandatory and the resolve should have been there in the first place

Matthieu Coudron

@teto

btw has stack no manpage :'( ?

@wygulmage

Anyone have success using recent versions of stack with wsl1? It seems to have switched to locking with fdLock, with is not supported by wsl1. I'm trying to find the sweet spot of a stack version that can still download resolvers (i.e., at least greater than 1.9) but that does not use fdLock.

wygulmage

@wygulmage

Well, the downside is I haven't figured out how to keep using stack in WSL 1. The upside is that cabal-install is about a million times better than it was when I switched to stack!
