I wanted to try out data parallel haskell. I followed the instructions on http://haskell.org/haskellwiki/Data_Parallel_Haskell/PackageNDP but I get the following error:

I'm sure I shouldn't have done this but I did get ndp to build. 1. In libraries/Makefile, I replaced
SUBDIRS += process pretty hpc template-haskell editline Cabal random haskell98
with
SUBDIRS += process pretty hpc template-haskell editline Cabal random haskell98 ndp
^^^ I suspect I didn't supply the correct build.mk but there weren't any clues on http://haskell.org/haskellwiki/Data_Parallel_Haskell/PackageNDP so I therefore used the one suggested on http://hackage.haskell.org/trac/ghc/wiki/Building/Hacking entitled "How to make GHC build quickly" 2. There was already a hack for ndp so I added my own
# Hack for ndp, as described above make.library.ndp: build.library.ndp
MYSUBDIRS = ndp
# Build the library using 'setup build' (not the default) $(foreach SUBDIR,$(MYSUBDIRS),build.library.$(SUBDIR)):\ build.library.%: stamp/configure.library.build$(CONFIGURE_STAMP_EXTRAS).% \ %/setup/Setup ifBuildable/ifBuildable if ifBuildable/ifBuildable $*; then \ cd $* && \ setup/Setup build $(addprefix --ghc-option=,$(GhcLibHcOpts)); \ setup/Setup register --inplace; \ fi
I'm guessing if I'd got the right build.mk I wouldn't have needed to do this. Dominic.
