Re: Unable to compile ghc from darcs

Hello Simon and Colin, This information is available on the Prequisites page of the GHC wiki; however, it's buried at the bottom of the page. I have updated the page to mention that a stable release version of GHC is needed when setting up for Linux and Windows, and I have changed the "Other" section to be called "Details" since this section describes in detail the software necessary for building GHC. http://hackage.haskell.org/trac/ghc/wiki/Building/Prerequisites Hope this helps other users in the future. -- Donnie Jones On Tue, Mar 31, 2009 at 8:33 AM, Simon Marlow wrote:

6.11.20090319 (formerly bootstrapped from 6.10.1).

Ah, there's your problem.  In general you can't bootstrap GHC using a development snapshot, we only support building using fixed released versions.

Cheers,        Simon
