Hello folks, Everything has been going beautifully with the latest versions of GHC 6.12, except that anything involving zlib dies at run-time. In ghci:
:m Codec.Compression.Zlib :m +Data.ByteString.Lazy.Char8 :s -XOverloadedStrings compress "hello"
*** Exception: user error (Codec.Compression.Zlib: incompatible zlib version) I'm running OS X 10.6 on a 64-bit machine. I've heard of folks running into this with GHC 6.10 on OS X 10.6, who got rid of it by removing mac-ports. I tried that and it didn't change anything. My mac-ports install should have all been universal binaries anyway. I imagine I'm somehow building against a 64-bit version of the zlib library, but I'm not sure at what step I'm supposed to do things different, or what precisely I'm supposed to do different. Thanks, Antoine
