Problem using Network package in GHC

Question

I have this simple code:

import Network
main = return ()

executing it with runhaskell fails:

>runhaskell test.hs
test.hs: C:\ghc\ghc-6.10.4\network-2.2.1.2\HSnetwork-2.2.1.2.o: unknown symbol `_getnameinfo'
test.hs: test.hs: unable to load package `network-2.2.1.2'

GHCi also gives simillar error message. What can I do about it?

I am using GHC 6.10.4 on Windows 2000.

Answer 1

Likely this means the binary distribution of GHC you installed was built against a different C library to the one on your system. Try reinstalling GHC using the Haskell Platform: http://hackage.haskell.org/platform/

Answer 2

You can use cabal to try and reinstall the package. I had similar behavior with the CGI library and forcing a reinstall fixed it.
