Hi,
I encountered a problem with Network.Socket in MacOS 10.5 Here is the code that I am testing,
----------------------------------------- ----------------------------------------- module Main where
import qualified Network.Socket as Socket
main :: IO () main = do { (hostname, _) <- Socket.getNameInfo [] True False (Socket.SockAddrUnix "localhost") -- (hostname, _) <- Socket.getNameInfo [] True False (Socket.SockAddrInet 9000 (127 + 0 * 256 + 0 * 256^2 + 1 * 256^3)) ; putStrLn (show hostname) }
Running the above code yields the following error ghc --make -O2 TestSocket.hs [1 of 1] Compiling Main ( TestSocket.hs, TestSocket.o ) Linking TestSocket ... $ ./TestSocket TestSocket: getNameInfo: does not exist (ai_family not supported)
If I switch to SockAddrInet instead, the error is gone.
I am using GHC 6.10.3 and Network 2.2.1
Is SockAddrUnix supposed to work on Mac OS X? Could you test it by e.g. writing a small C program that uses it? -- Johan
