So I had to disable genvalidity-path too
How is that even possible? Where do two instances like this come from:
• Overlapping instances for Eq (Maybe (Path Rel Dir))
arising from a use of ‘==’
Matching instance:
instance Eq a => Eq (Maybe a) -- Defined in ‘GHC.Maybe’
I can't repro this because GHC 9.6.3 isn't in nixpkgs yet and lts-21.14 isn't out yet.
PR welcome, I guess. I'm a bit sick of having to keep up with base upgrades breaking things that are really not fancy.
I'm building with GHC 9.8 and still can't repro it. @juhp how did you?
Can't fix it if I can't repro it.
Well LTS 21 is ghc-9.4.7
I haven't tried to reproduce this locally, but if i were going to I would try something like stack --resolver lts build
.
I hit this while trying to build new Stackage LTS 21.14
