I've been using ghc 6.10.3 on 64-bit Linux to compile my application, and it runs OK, modulo bugs. I want to debug a problem, so I load it in ghci, but when i type main I get: Loading package network-2.2.1.1 ... GHCi runtime linker: fatal error: I found a duplicate definition for symbol my_inet_ntoa whilst processing object file /usr/lib64/ghc-6.10.3/network-2.2.1.1/HSnetwork-2.2.1.1.o This could be caused by: * Loading two different object files which export the same symbol * Specifying the same object file twice on the GHCi command line * An incorrect `package.conf' entry, causing some object to be loaded twice. GHCi cannot safely continue in this situation. Exiting now. Sorry. Why would ghci have a problem, but not ghc? -- Colin Adams Preston Lancashire
