Hi, instances for the system classes CCallable and CReturnable for the various Word* and Int* types were added just after 2.10 was released, so to fix this without upgrading to ghc-3.xx you need to add the following lines to StdDIS.gc: instance CCallable Word32 instance CReturnable Word32 instance CCallable Int32 instance CReturnable Int32 hope that helps, --Sigbjorn
