I'm trying to build GHC from darcs. Unfortunately compilation fails with the following error:
... cpphs: #error Please define LEFTMOST_BIT to be 2^(SIZEOF_HSWORD*8-1) in GHC/Num.lhs at line 27 col 1 make[1]: *** [doc.library.base] Error 1 make[1]: Leaving directory `/home/bas/development/haskell/ghc/libraries' make: *** [stage1] Error 2 ...
The following is the part where the error occurs in libraries/base/GHC/Num.lhs : ... #include "MachDeps.h" #if SIZEOF_HSWORD == 4
This is a cpphs bug - IIRC it wasn't recursively expanding SIZEOF_HSWORD. Either install cpphs from darcs (I don't think there is a release with the fix yet) or uninstall it so that cpp is used instead.
Thanks Ian
After uninstalling cpphs the error no longer occurs, thanks! However the build now crashes when running Haddock on Cabal: ... ifBuildable/ifBuildable Cabal setup/Setup haddock Preprocessing library Cabal-1.1.7... Running Haddock for Cabal-1.1.7...

Currently I have version 0.8. Installing darcs version right now... Thanks, Bas van Dijk
