GHC X.Y packages

These GHC package are available for current Fedora releases and EPEL 9:

  • ghc8.10 (8.10.7) (not F37 or epel9)
  • ghc9.0 (9.0.2)
  • ghc9.2 (9.2.8)
  • ghc9.4 (9.4.5)
  • ghc9.6 (9.6.2)

They can be parallel installed.

  • If you want to make one of them default install ghcX.Y-compiler-default

Note the former ghc module streams are now deprecated.

Haskell Coprs

Coprs for EPEL 7

These versions of ghc are available:

If you have Fedora Haskell libraries installed which are not part of ghc, you will need to remove them all first (easiest just to remove ghc-base) to avoid package dependency conflicts


  • ghc-9.4
  • add cabal-installX.Y
  • help improve FedoraReview/plugins/
  • document ghc and package update workflow (GHC_Update_SOP)
  • package larger subset of LTS in Copr
