Re: [Haskell-cafe] Can't install vector-0.10.9.1 on OS X Maverick

I'm trying to fiddle with clang scripts from Manuel Chakavarty and this one: https://gist.github.com/mzero/7245290 the former works (vector builds fine), but when installing Snap it generates the following error: Loading package network-2.4.2.0 ... GHCi runtime linker: fatal error: I found a duplicate definition for symbol _hsnet_freeaddrinfo whilst processing object file /Users/adinapoli/programming/haskell/faceguess/.cabal-sandbox/lib/x86_64-osx-ghc-7.6.3/network-2.4.2.0/libHSnetwork-2.4.2.0.a 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. Failed to install snap-0.13.0.4 cabal: Error: some packages failed to install: snap-0.13.0.4 failed during the building phase. The exception was: ExitFailure 1 I haven't tried the latter, though. A. On 2 November 2013 22:23, Carter Schonwald wrote:

i have no clue. Doesn't GHC also come prebuilt with Vector?

might be worth filing a ticket on GHC track too. perhaps.

Hi Carter,

I do have Xcode 5 installed, this is the strange thing. Do you suggest to try reinstall Xcode or to downgrade gcc? (I'm using 4.8 atm). Also, the error is triggered by base, do you think I should try reinstalling ghc compiling with the newly installed gcc?

Thanks, A.

You need to have xcode 5 installed if you wish for the lib issues to go way if you're using the gcc approach, it sounds like you don't have xcode 5 installed.

I've did the trick of installing gcc-4.8 as described here:

http://cp.reddit.com/r/haskell/comments/1ozukp/anyone_running_ghc_763_on_osx...

I'm running a compiled version of ghc 7.6.3 (so not installed via the Haskell platform).

Have anyone stumbled upon this?

Thanks, Alfredo
