Latest release build failing when building ghcide-2.5.0.0

[DentFuse]

Hi, I'm relatively new to Haskell. I was trying to use HLS but it was crashing while initialising, that's when I stumbled upon this project.

I've downloaded the latest release and was trying to build it using cabal to get the executable, however the build seems to be failing with the following error:

src/Development/IDE/Import/FindImports.hs:225:40: error: [GHC-83865]
    • Couldn't match type ‘(Unit, UnusableUnit)’ with ‘UnusableUnit’
      Expected: [UnusableUnit]
        Actual: [(Unit, UnusableUnit)]
    • In the expression: unusables'
      In a record update at field ‘fr_unusables’,
      with type constructor ‘FindResult’
      and data constructor ‘NotFound’.

Error: [Cabal-7125]
Failed to build ghcide-2.5.0.0 (which is required by exe:static-ls from static-ls-0.1.2). See the build log above for details.

Same error when installing directly via cabal too.

Also, it would great if some setup instructions could be provided, I've got all the other plugins setup, only missing the binary.

Hi! Happy to help debug - could you provide which ghc version you're on? It could be an older version possibly

[DentFuse]

Hey, thank you for your reply.

❯ ghc --version
The Glorious Glasgow Haskell Compilation System, version 9.6.6

Also I did a bit of digging, in the archive that is being downloaded from Hackage, this piece of code doesn't even exist. No clue where it is being picked up from.

[josephsumabat]

Oh I see the releases may have been a bit misleading - they were simply the hackage packaged version. If you build from source you shouldn't run into the issue anymore when I get the chance I'll upload the latest version to hackage!

[DentFuse]

Sure, I'll try building from source once. Thanks!
