Hi Henk-Jan, I believe cabal adds a -O on the command line, perhaps try ghc --make -O (after deleting all object files) Thanks Neil On Mon, Feb 16, 2009 at 12:04 PM, Henk-Jan van Tuyl wrote:

L.S.,

I have updated wxFruit to compile with GHC 6.10.1, but when I compil using the commands: runhaskell Setup configure & runhaskell Setup build & runhaskell Setup install and run paddle.exe, I get the message: paddle: <<loop>>

If I compile with: ghc --make paddle , the game starts normally.

Any idea how I can solve this?

Some more data: Using: Yampa-0.9.2.3 wxFruit-0.1.1 from Hackage, updated GHC 6.10.1 Windows XP

This paddle.exe works fine

I suspect this may be an instance of http://hackage.haskell.org/trac/ghc/ticket/2985 Or (less likely) http://hackage.haskell.org/trac/ghc/ticket/2722 Can you try with the HEAD? Or the 6.10 branch (which includes the fix for #2985)?
