[solved] xmonad trouble following update (missing haskell packages)

ljwall · 2017-10-23 12:56:44

Hello,

Last night I did `pacman -Syu`, with the following upgrades:

[2017-10-22 21:21] [PACMAN] Running 'pacman -Syu'
[2017-10-22 21:21] [PACMAN] synchronizing package lists

[2017-10-22 21:22] [ALPM] upgraded ghc (8.2.1-2 -> 8.2.1-3)
[2017-10-22 21:22] [ALPM] upgraded linux (4.13.7-1 -> 4.13.8-1)

Following this, `xmonad --recompile` seems to be no longer working. Fairly sure I've not done anything else that would have broken this.

I get this:

➜  ~ xmonad --recompile

Please check the file for errors.

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

I've tried compiling my xmonad.hs directly with ghc (in order to be able to use -v option) and get this (clipped for brevity). Without the -dynamic flag it also does not fin Prelude or System.IO, but it was like this before anyway, so don't think this is the issue.

Okay, in case anyone else experiences similar issues, this is what the issue seemed to be: The arch package ghc-libs (8.2.1) updates the file /usr/lib/ghc-8.2.1/package.conf.d/package.cache, which is used by ghc to know what Haskell packages are available.

`ghc-pkg list` will list the packages ghc thinks are available to use. xmonad should be listed there. It was not there for me.

Running `sudo ghc-pkg recache` to regenerate /usr/lib/ghc-8.2.1/package.conf.d/package.cache fixed the issue.

`ghc-pkg list` now lists xmonad and xmonad-contrib, and `xmonad --recompile` works as expected.

Thanks. Fixes my problem too.
My xmonad compilation failed just after updating to latest ghc 8.2.1-3.
