Package: guix

Version: 1.2.0-17.ec7fb6

I am trying to recompile xmonad with a fairly simple xmonad.hs

The package itself builds, installs, and runs correctly, but it throws errors when recompiling my configuration. Configuration is very short but is pasted here: http://paste.debian.net/1190543/

The same error is thrown when attempting to compile xmonad with ghc directly, and inside and out of xmonad's build environment.

The following is the error that is printed when attempting to recompile xmonad from within the build environment for xmonad within the directory ~/.xmonad/ containing xmonad.hs

[env]$ xmonad --recompile
XMonad will use ghc to recompile, because "/home/fever/.xmonad/build" does not exist.
Error detected while loading xmonad configuration file: /home/fever/.xmonad/xmonad.hs                    

xmonad.hs:1:1: error:
    Could not find module ‘XMonad’
    Perhaps you meant DsMonad (needs flag -package-key ghc-8.6.5)
    Use -v to see a list of the files searched for.
  |
1 | import XMonad
  | ^^^^^^^^^^^^^

xmonad.hs:2:1: error:
    Could not find module ‘XMonad.Config.Desktop’
    Use -v to see a list of the files searched for.
  |
2 | import XMonad.Config.Desktop
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Please check the file for errors.

xmonad: xmessage: executeFile: does not exist (No such file or directory)
