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...
Warning: cannot use package base-2.1:

The respected code from libraries/Cabal/Distribution/PreProcess.hs
(line 115 and onwards a bit):
data PreProcessor = PreProcessor {
-- Is the output of the pre-processor platform independent? eg happy
output
-- is portable haskell but c2hs's output is platform dependent.
-- This matters since only platform independent generated code can
be
-- inlcuded into a source tarball.
platformIndependent :: Bool,
-- TODO: deal with pre-processors that have implementaion dependent
output
-- eg alex and happy have --ghc flags. However we can't really
inlcude
-- ghc-specific code into supposedly portable source tarballs.
runPreProcessor :: (FilePath, FilePath) -- Location of the source
file relative to a base dir
-> (FilePath, FilePath) -- Output file name,
relative to an output base dir
-> Int -- verbosity
-> IO () -- Should exit if the preprocessor fails
}
Do I maybe need a newer Haddock for this? Currently I have version
0.8. Installing darcs version right now...
Thanks,
Bas van Dijk
