Hi, I pulled jhc sources (jhc, doc, haskell98, QuickCheck) from darcs and tried building jhc. But the build exits with the following error: jhc$ make ghc -O -ignore-package lang -pgmF drift-ghc -F -W -fno-warn-unused-matches -i. -iFrontEnd -package mtl -package unix -package QuickCheck -fwarn-type-defaults -fallow-undecidable-instances -fglasgow-exts -fallow-overlapping-instances --make Main.hs -o jhc --snip-- . . . --snip-- /home/haskell/DrIFT/bin/DrIFT DerivingDrift/StandardRules.hs -o /tmp/ghc12711_0/ghc12711_151.hspp /home/haskell/DrIFT/bin/DrIFT E/LambdaLift.hs -o /tmp/ghc12711_0/ghc12711_159.hspp [ 60 of 162] Compiling Info.Binary[boot] ( Info/Binary.hs-boot, nothing ) [ 95 of 162] Compiling DataConstructors[boot] ( DataConstructors.hs-boot, nothing ) [110 of 162] Compiling Representation ( FrontEnd/Representation.hs, FrontEnd/Representation.o ) FrontEnd/Representation.hs:350:8: parse error on input `instance' jhc$ am using 6.6.1 ghc, happy is 1.16 and DrIFT version is 2.2.3; would really appreciate if you could let me know what went wrong. thanks -ganesh
