Xmonad not reading xmonad.hs

Help
1

Good evening!

I just installed nixOS, using my old config, but something seems to have broken in the process. it seems most things are working besides my xmonad config.

I have it in ~/.config/xmonad but it just isn’t getting read. I’m posting this from a vanilla xmonad session. :frowning:

if I xmonad --recompile this is the output:

XMonad will use stack ghc --stack-yaml "/home/dot/.config/xmonad/stack.yaml" to recompile.
XMonad recompiling (forced).
xmonad: stack: runProc: exec: does not exist (No such file or directory)

and

 $ which xmonad
/run/current-system/sw/bin/xmonad

any ideas? I really need to get back to work. :frowning:

Sounds like it wants to use stack to build your xmonad.hs but you don’t have stack installed.

Thanks so much for the quick reply, @ElvishJerricco!!

now I installed stack and this is my output on xmonad --recompile

XMonad will use stack ghc --stack-yaml "/home/dot/.config/xmonad/stack.yaml" to recompile.
XMonad recompiling (forced).

Please check the file for errors.

I have ghc-9.0.2 on my system. I’m going to do more digging unless somebody has a clear answer. <3

ope! I removed my stack.yaml from my ~/.config/xmonad and I’m good! <3 thanks so much for the tip, @ElvishJerricco !!

FTR record that (quite unhelpful) error message is due to stack trying to pull a GHC version from nixpkgs (via the automatic Nix integration) that has been removed since. The solution for this kind of problem is to either

  • provide a nixpkgs version to stack that still has this GHC version
  • or update the stack resolver to a version that uses a GHC version that is available from nixpkgs.

I actually just stopped it from using stack to build xmonad by renaming stack.yaml to stack.yaml.bak
