Re: Packaging Haskell libraries

Hi, Till -

Is packaging them as

haskell-X11
haskell-X11-extras
haskell-mtl

ok?

No, I'm afraid not. There are already two Haskell implementations available in Extras, hugs and ghc. Additionally, the Haskell compilers make no attempt to preserve ABI compatibility across releases.

For these reasons, the tiny handful of existing Haskell packages that are already packaged are prefixed with the name and version of the compiler they're built against, not with a simple "haskell-". For example, the Gtk2Hs package is named ghc66-gtk2hs. This is a pretty reasonable naming scheme.

Finally, packaging Haskell libraries is a subtle business, because a Haskell compiler has its own package manager that needs to be treated properly, or you'll have a terrible mess on your hands where RPM and your Haskell implementation have different notions as to what's installed. In particular with the X11 and mtl packages, older versions of those are already shipped with ghc itself.

You should take a look at my cabal-rpm tool, which generates a clean RPM spec file for Haskell packages that are packaged with the Cabal system:

Jens Petersen has been talking about establishing a Haskell SIG, which would be a good place to air issues like these before bringing them up for wider discussion.
