Re: xmonad, xmonad-contrib & GHC_PACKAGE_PATH?

[John Soo]

Hello,

I thought I had opened an issue about this but I must have kept it in my TODOs. 
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?

The workaround is to do this (altering for your host system and required 
libraries):

ghc -o ~/.xmonad/xmonad-x86_64-linux \
-package-db $(guix build ghc-xmonad-contrib | grep -v 
static)/lib/ghc-8.6.5/ghc-xmonad-contrib-0.16.conf.d/ \
-package-db $(guix build ghc-dbus | grep -v 
static)/lib/ghc-8.6.5/ghc-dbus-1.2.7.conf.d/ \
-package-db $GUIX_PROFILE/lib/ghc-8.6.5/package.conf.d/ \
-dynamic xmonad.hs

Hope that helps,

John
