Attached is a patch to give more informative failure messages in the
Win32 package. Currently we get:
GHCi, version 6.10.2: http://www.haskell.org/ghc/ :? for help
Prelude> :m System.Directory
Prelude System.Directory> removeFile "wibble"
*** Exception: DeleteFile: does not exist (The system cannot find the file speci
Prelude System.Directory> removeFile "c:/ghc/ghc-6.10.2/bin/ghci.exe"
*** Exception: DeleteFile: permission denied (Access is denied.)
Now, we should get:
*** Exception: DeleteFile "wibble": does not exist (The system cannot
find the file specified.)
*** Exception: DeleteFile "c:/ghc/ghc-6.10.2/bin/ghci.exe": permission
denied (Access is denied.)
I have compiled the patches, but not tested them. When I do, I get
errors about linking, which I'm pretty sure have nothing to do with my
: C:\Program Files\Haskell\Win32-18.104.22.168\ghc-6.10.2\HSWin32-22.214.171.124.o: unknown s
I suspect it's because Win32 is built and distributed with GHC.
Also, I noticed that:
$ cabal install Win32 --global --reinstall
Module `Control.Exception' does not export `onException'
cabal: Error: some packages failed to install:
Win32-126.96.36.199 failed during the building phase. The exception was:
exit: ExitFailure 1
I'm now left with a dead version of GHC - for future reference, is
there a sequence of steps that would have worked to install Win32 and
start using the new one?
