`stack build` failed with `/usr/bin/ld: final link failed` on Archlinux - haskell

Question

I'm trying to use the req package (http://hackage.haskell.org/package/req) in a Haskell project, with stack.
So far, I've done stack new my-project, stack setup, stack build and stack exec my-project-exe all fine.
Have added req to the cabal file like so:
name: my-project
version: 0.1.0.0
synopsis: Short description of your package
homepage: https://github.com/githubuser/#readme
license: BSD3
license-file: LICENSE
author: Author name here
maintainer: example#example.com
copyright: 2017 Author name here
category: Web
build-type: Simple
extra-source-files: README.md
cabal-version: >=1.10
library
hs-source-dirs: src
exposed-modules: Lib
build-depends: base >= 4.7 && < 5
, req -- THIS IS THE LINE IVE ADDED
default-language: Haskell2010
executable my-project-exe
hs-source-dirs: app
main-is: Main.hs
ghc-options: -threaded -rtsopts -with-rtsopts=-N
build-depends: base
, my-project
default-language: Haskell2010
test-suite my-project-test
type: exitcode-stdio-1.0
hs-source-dirs: test
main-is: Spec.hs
build-depends: base
, my-project
ghc-options: -threaded -rtsopts -with-rtsopts=-N
default-language: Haskell2010
source-repository head
type: git
location: https://github.com/githubuser/my-project
And finally, cut and paste the example from the req readme into src/Lib.hs, changing the function name like so:
{-# LANGUAGE OverloadedStrings #-}
{-# OPTIONS_GHC -fno-warn-orphans #-}
module Lib
( someFunc
) where
import Control.Exception (throwIO)
import Network.HTTP.Req
import Data.Aeson
-- Just make your monad stack an instance of MonadHttp in your application
-- and start making requests, enjoy automatic connection sharing.
instance MonadHttp IO where
handleHttpException = throwIO
someFunc :: IO ()
someFunc = do
let payload = object
[ "foo" .= (10 :: Int)
, "bar" .= (20 :: Int) ]
-- One function, full power and flexibility.
r <- req POST -- method
(https "httpbin.org" /: "post") -- safe by construction URL
(ReqBodyJson payload) -- use built-in options or add your own
jsonResponse -- specify how to interpret response
mempty -- query params, headers, explicit port number, etc.
print (responseBody r :: Value)
And now stack build is erroring:

Any help much appreciated!

Answer 1

This issue has been plaguing users of Arch Linux for a few months. It appears to be related to the ncurses library, and possibly due to Arch Linux dynamically linking Haskell packages, whilst most (all?) other distros use static linking.
The current work around involves using the ghc-build: nopie option for the stack ghc version, and installing ncurses5-compat-libs from the AUR.
If you wish to set this globally, you can set it in your ~/.stack/config.yaml, so it applies to all projects you build with stack.
A bug report is currently open here, and some related discussion can be found on the arch forums or the stack github.

Answer 2

For me deleting ~/.stack and using
stack setup --ghc-build=ncurses6
and adding
ghc-build: ncurses6
to
~/.stack/config.yaml
resolved this.
Addendum:
ghc-build: tinfo6
and
stack setup --ghc-build=tinfo6
worked even better for me.
