16:09 <__monty__> I'm still trying to get cross-compiling to work. Currently running into a build error I don't understand. https://github.com/toonn/taskell/runs/1846286706?check_suite_focus=true#step:5:16606

16:11 <__monty__> Afaiu vty 5.25.1 has the terminfo >= 0.3 && < 0.5 constraint. Since this is a stack project I looked into the version in stackage snapshots and it's been 0.4... since at least LTS 13.x

16:11 <__monty__> Is this "patchelf: wrong ELF type" error related maybe?

16:14 <ocharles> No, that's fine I think. Stranger is that there is no `--dependency` line for terminfo at all - is that right?

17:06 <__monty__> ocharles: terminfo only depends on base, so I think it is?

17:08 <ocharles> I mean the thing that's failing to build wants terminfo, but it's not in the --dependency list

17:11 <__monty__> Oh, you're right. Weird.

20:00 <jlode> Hey. Is there any hidden knowledge I need to be aware of to get cache hits? I'm currently compiling GHC from source. I've configured caches, and I've tried using almost every single combination of nixpkgs/ghc that is supported

20:01 <jlode> Does anyone have a known working configuration that I can just copy?

20:12 <jlode> Looks like I already had a nix.conf which overrides the system-wide cache configuration. I don't know which tool created that file, but I'm assuming that's my issue

20:13 <jlode> there we go :) nice
