Hi Mike, Sigbjorn, Simon, Thanks so much for the pointers. Sigbjorn's suggestion to check out the patch was what finally fixed my problem. BTW, ghci still does work for me. I get this lovely message: F:\stuff>ghci -package win32 hello.lhs C:\ghc-5.02\bin\ghc.exe: file `P?B' does not exist The ? is acutally a spade symbol in my command window. Anyway, I hope that stops the stupid complaints from my direction for a while. And now I know what and where I should be looking for the bug list. SourceForge has just enough of a bug list to fool me into thinking that's where I should be looking. Thanks Again, John Heron Sigbjorn Finne wrote:

Hi,
have a look at the top of that file - it tells you what options you need to feed GHC to compile the example (well, the options it suggests are deprecated by The Powers That Be; you ought to use "-package" instead of "-syslib").
Simpler yet, try running it via ghci:
c:\src\haskell> ghci -package win32 hello.lhs
and then evaluate 'main'.

btw, notice that ghc-5.02 currently has got a problem or two with the Win32 library -- see
