I will definitely look at nix and cabal new-build. My current setup works but makes me ship insanely oversized tarballs... The project is a bosh-release (https://bosh.io), more precisely a cloud provider interface for Kubernetes ( https://github.com/sap/bosh-kubernetes-cpi-release). In order to have offline compilation with stack I currently have to package GHC thrice (darwin, linux and old-linux (centos)) plus half of stackage for my dependencies. Offline compilation is probably what will not make `nix-shell -p haskell.compiler.integer-simple.ghc802` particularly simple. Or will it still? Best Jan David Johnson schrieb am Mo., 17.

One (simple?) solution is to use the Nix package manager. Integer-simple GHCs were recently added (available on both Darwin and Linux afaik). After downloading the nix package manager, simply run:

*nix-shell -p haskell.compiler.integer-simple.ghc802*

The above command will put you into a shell with an integer-simple GHC-8.0.2

For more info on nix and haskell, this is a good guide: https://github.com/Gabriel439/haskell-nix

Along with what is mentioned in the nixpkgs manual. http://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure

Hi,

I would like to have an integer-simple GHC for Mac and Linux. As there is no official download for that I should probably build it myself.

My CI server is running Linux containers though.

When https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling says "build must equal host", does that mean I cannot produce a mac ghc with Linux ci server? How do others produce ghc for mac or Windows?
