If you weren't planning on hacking editline, it's probably easiest to just rm -rf the libraries/editline directory and do another "darcs-all get" to replace it with a consistent version. Otherwise, send me the darcs --changes of that repo and I can take a look at it.

Thanks for your help but now I'm getting a mismatch between ghc and ghc-pkg. I'm not sure how to fix this.

From the above error, I suspect that you need to run "make distclean" in the root of the source tree, then try building again. (I usually run that command every time before/after pulling from darcs.)

Let me know if that helps, -Judah

This is becoming a bit of an odyssey ("a series of vicissitudes"). I now get a bug in ghc. Should I report it? Dominic.

Sorry about this -- it's my fault. I did validate a fix to the desugarer, but ndp isn't part of 'validate'. Turns out that the change to the desugarer provoked quite subtle and longstanding bug in the simplifier. To get rolling again, use -fno-ds-multi-tyvar. Or just don't compile NDP. I'll commit a patch shortly.

Great! I'm copying Roman, Gabi, and Manuel so they know you're doing this. Much of GHC is very stable but NDP emphatically isn't. We're working hard on it, the code is changing a lot, so you may well get short-lived build difficulties. So do have a go, but show us your code, and keep us in touch with what happens. Simon

Ok but doesn't that rebuild everything not just the bits that have changed?

Correct. Ideally, the makefiles would be able to detect any changes after a pull, but in practice I've found that they get easily confused. Incidentally, if you haven't already, you can make each build much faster by adding a mk/build.mk file as in: http://hackage.haskell.org/trac/ghc/wiki/Building/Hacking -Judah

Enough stuff usually changes that it's necessary (and for whatever reason dependencies don't catch enough of it).
