Detailed Description

Bumping ghc version requires a complete rebuild of all Haskell packages against the new version.

Benefit to Fedora

GHC 7.4 is a major new version of ghc with many new compiler features and improvements.

Scope

• Update Rawhide to haskell-platform-2011.4.0.0 [in progress]
• Bootstrap ghc-7.4 in rawhide.
• Finalize ghc-rpm-macros for F17 (drop ghc-prof provides).
• Refresh and rebuild all Haskell packages with appropriate version bumps.
• Test packages in rawhide/f17

How To Test

• yum install haskell-platform
• yum install @haskell
• yum install xmonad
• yum install ghc-*-devel
• yum install pandoc

User Experience

Fedora users will have the latest version of GHC available to them.

Dependencies

ghc-7.4.1 release is expected soon. haskell-platform release for ghc-7.4 expected next year.

Contingency Plan

If ghc-7.4.1 is not released in good time for Alpha then will probably just target haskell-platform-2011.4 for Fedora 17, and wait with ghc-7.4 until F18.
