Re: [Haskell-cafe] Problems building lambdabot on osx

I didn't have any trouble building lambdabot when linking to readline built through Homebrew. Currently using Lion, Xcode 4.1, and GHC 7.0.4. On Aug 9, 2011, at 11:59 AM, Brandon Allbery wrote:

cabal install --extra-lib-dirs=/usr/lib

That leaves a whole mess of link errors against libHSreadline:

Yes, because now it's finding the system readline, which isn't actually readline (Apple ships a "readline" which is actually BSD "editline", so you get missing symbols for things editline doesn't support such as completion). I think you'll need to temporarily deactivate MacPorts' iconv instead of using --extra-lib-dirs.

This can't really be fixed by either GHC or MacPorts; there doesn't seem to be a good solution as yet, although the MacPorts folks may end up implementing a hacky solution because Apple has introduced *another* MacPorts-breaking library conflict in Lion (libnotify).
