Re: xmonad, xmonad-contrib & GHC_PACKAGE_PATH?

[William <wonko7@gmail.com>]

Thanks both of you!
This works for me:

(use-modules (gnu)
             (gnu packages commencement)
             (guix profiles))
(use-package-modules haskell haskell-xyz wm gcc)
(packages->manifest (list gcc-toolchain ghc ghc-hostname
ghc-xmonad-contrib xmonad))

and then xmonad --recompile Just Works.

Have a nice day!

The haskell-build-system does not put outputs in the right place for the ghc profile hook. xmonad --recompile should Just Work with any installed haskell-build-system libraries installed via guix. I’ve been meaning to look at this for a while but I have not had the chance. Could you please open a fresh issue?
