Stack: ghc-8.2.1-rc2 issue on Arch linux

Created on 18 May 2017 · 1Comment · Source: commercialhaskell/stack

I have followed this guide:
http://taylor.fausak.me/2017/05/17/testing-ghc-release-candidates-with-stack/

It works on Windows
But on Arch Linux I get:

No information found for ghc-8.2.0.20170507.
Supported versions for OS key 'linux64-ncurses6': GhcVersion 7.10.3, GhcVersion 8.0.1, GhcVersion 8.0.2

Arch uses different GHC bindists than the default because it uses libncurses6 (whereas stock GHC bindists are build to dynamic link with libtinfo5). So there are two ways to progress:

Build your own GHC 8.2.1-rc2 bindist from source on Arch and reference that in the setup-info (replacing linux64 with linux64-ncurses6 as the key).
Install ncurses5-compat-libs from AUR and then force Stack to use the standard GHC bindist by doing something like stack --ghc-build=standard setup.
