After a recent upgrade of Mac OS X from Tiger to Snow Leopard, I installed the Haskell Platform. I installed genuine readline using MacPorts.
Now I cannot install the readline package, due to the well-known problem that configure finds the fake readline that comes with Mac OS X and refuses to proceed.
I have tried the various solutions suggested in:
http://hackage.haskell.org/trac/ghc/ticket/3121 http://www.haskell.org/pipermail/libraries/2009-May/011595.html http://hackage.haskell.org/trac/hackage/ticket/631
and various combinations of them. Nothing helped, the same problem always occurred.
Any new ideas?
This worked for me on Snow Leopard: export CFLAGS=-m32 cabal install readline --configure-option=--with-readline-includes=/opt/local/include --configure-option=--with-readline-libraries=/opt/local/lib I had previously set MacPorts to compile all of its libraries 32-bit, which makes the first line necessary for the configure script to link properly. -Judah
