Hi Guix, I looked at the wishlist on libreplanet and saw stack was on the list. Also after the recent thread on haskell and clojure development I realized stack would help out there. I tried to package it which seems straightforward. I got the dependencies built and linted but stack itself is failing with the following: gcc: error trying to exec '/gnu/store/...-gcc-7.4.0/libexec/gcc/x86_64-unknown-linux-gnu/7.4.0/collect2': execv: Argument list too long This looks a lot like the nix issue here: https://github.com/NixOS/nixpkgs/issues/41340 I thought I would share my work and maybe someone could help. Thanks, John
