Those libraries are not distributed with the compiler. Use either The Haskell Platform, or hackage to get those packages. On Saturday, May 1, 2010, Roly Perera wrote:

Hi,

I've just upgraded from 6.10.1 to 6.12.1 and can't seem to find all the library documentation. This page is apparently the documentation root:

http://www.haskell.org/ghc/docs/6.12.1/html/

but if I click through to the Haskell Hierarchical Libraries page

http://www.haskell.org/ghc/docs/6.12.1/html/libraries/index.html

I can't for example find Control.Monad.State. I guess I'm missing something obvious about how things are organised?

This is part of the mtl library. Prior to GHC 6.10.4, this used to be part of the "extralibs" that were often bundled with GHC and thus were on GHC's documentation page. With 6.10.4, extralibs was replaced with the Haskell Platform and as such is no longer featured on GHC's documentation page. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
