This might be due to some recent library version updates perhaps, I dunno.

BTW JFYI we are hoping to release LTS 19 fairly soon.

[lifer0se]

Same issue using cabal install on Arch Linux. Any way to fix the issue? Does it have to do with outdated sources?

I'll try making a cabal project using the source to see if I can replicate the issue there.

[maralorn]

This issue is caused by the simplified subsumption change in ghc 9. It is easy to fix by eta expanding the functions which have the type error in one of their arguments.

[iharh]

Could anyone suggest the latest version of working ghc/stack-lts to be able to build taffybar with?

@Mikutut oof thats some awful extra deps. Is all of that really necessary?

@Mikutut oof thats some awful extra deps. Is all of that really necessary?

At first I only changed the version of gi-harfbuzz, because of compilation error, but then I had to add all those other extra deps to get taffybar to compile properly (mismatching versions of gi-related libraries)

[felixonmars]

#541 Fixes this issue for me under Arch Linux. A release could probably help here :)

[colonelpanic8]

@felixonmars ah good to know. We do have a new release now. I might give getting it back in to stackage a shot.
