L.S., I am trying to run Dr Haskell, using the YHC binary I downloaded (http://www.cs.york.ac.uk/fp/yhc/snapshot/yhc-latest.zip) but I get the message that the corep option is not valid. According to http://yhc06.blogspot.com/2006/09/yhccore-api-available.html this option should exist, but it is not listed with command yhc -? (By the way, the help info uses "yhcc" instead of "yhc".) Another problem is, that I cannot get the compiler compiled at my Windows XP system (I am using GHC 6.4, so I can use wxHaskell, and Darcs 1.0.3) After running Makefile.bat all I get the messages: Dependancy found (ghc) Dependancy found (darcs) Copying patch 37 of 37... done! Applying patches to the "working" directory... darcs: failed to read patch in get_extra: Thu Apr 22 18:39:38 West-Europa (zomertijd) 2004 malcolm * [cpphs @ 2004-04-22 16:39:38 by malcolm] Initial revision Perhaps this is a 'partial' repository?
