Good morning I have a query about compiling the original version of the HTTP implementation in Windows (http://homepages.paradise.net.nz/warrickg/haskell/http/). Using the compile commands stipulated a series of similar errors to do with the HTTP module appear. They are to do with a type mismatch, one of these errors for example is: ./HTTP.hs:592: Couldn't match 'IOError' against 'Exception' Expected type: Exception -> IO (Either a [Char]) Inferred type: IOError -> IO (Either ConnError b) In the application 'handleSocketError sk' In the second argument of 'Control.Exception.catch', namely '(handleSocketError sk)' Line 592 is: readBlock sk n = (liftM Right $ fn n) `Exception.catch` (handleSocketError sk) Have hacked about for some time to no avail. I don't know why this occurs because the code appears exactly the same in the updated version (http://www.dtek.chalmers.se/~d00bring/haskell-xml-rpc/http.html) and that compiles, albeit in linux only due to the Cabal constraint. I need it to work in Windows though so must use the original version. (I need it to compile using GHC 6.2.2) If anybody has seen this problem before or knows how to correct it I'd be very interested in your assistance :-) cheers to all david
