sounds like missing readline package during configure
be warned - there have been endless discussions on readline (because of licensing issues).
best regards, Johannes.
Johannes, Thanks for the reply and I'm sure you are right but I'm still stuck with knowing what to do about it. I think I have a readline:
dom@lagrange:~/ghc> ls /usr/include/readline/ chardefs.h keymaps.h rlconf.h rltypedefs.h history.h readline.h rlstdc.h tilde.h
I couldn't see anywhere on http://hackage.haskell.org/trac/ghc/wiki/Building/Hacking where it mentioned readline. Ok I can see in config.log that I don't have editline. That sounds very suspicious. Mind you I'm not sure where to get it from for opensuse. I'll have a hunt around. Dominic.
