Do you have libedit on your linux machine (because I haven't)?
I do not know what is libedit and where to find it.
It's the library needed for editline http://hackage.haskell.org/cgi-bin/hackage-scripts/package/editline
editline is the replacement of readline. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/readline
1. ghc-pkg list does not show the editline package. 2. The arrow keys and backspace do not work in ghci. This is so -- on my machine, under Debian Linux.
The advantage is ghci works without editline and readline. The disadvantage is if you want arrow keys and backspace to work, you should have installed http://www.thrysoee.dk/editline/ first.
Is this due to some deficiency in Debian Linux installation or this is a bug in the GHC installation?
A (debian) package manager could install editline (and gmp) before ghc. (Unfortunately user programs may depend on those extra libraries, too.)
libedit on Debian is very out-dated[1]. Haskell bindings (editline) doesn't compile against it (at least I could not compile it). 1. http://packages.qa.debian.org/e/editline.html -- Roman I. Cheplyaka :: http://ro-che.info/ kzm: My program contains a bug. How ungrateful, after all I've done for it.
