[root@localhost ghc-6.6.1]# ghc /usr/local/lib/ghc-6.6.1/ghc-6.6.1: error while loading shared libraries: libreadline.so.4: cannot open shared object file: No such file or directory #
So, I conclude that Haskell is not ready for prime time, if it cannot install itself correclty including shared libs in a standard Fedora Core 6 system.
Don't back out yet, the water's lovely! :-) GHC uses libreadline 4 (as mentioned in the error message), whereas most systems seem to come only with version 5. The place where you downloaded the GHC tarball (presumably haskell.org/ghc ?) also has a compatibility version that includes the older libreadline. If you install v4 now then GHC will work just fine. I'd guess there should be a way to get the libreadline4 installed from your package manager. Something like "sudo yum install libreadline4" maybe? I don't use FC myself, so can't help further. Cheers, D.
