stgSyn/CoreToStg.lhs:1112: Couldn't match `#' against `*'

[Mike Thomas]

Hi there.   While building current CVS GHC under Windows with a CVS version of GHC from 26 April I get the error at the end of this message (short extract here):   ---------------------------------------------------------------------------------------------- stgSyn/CoreToStg.lhs:1112:     Couldn't match `#' against `*'     When matching types `GHC.Prim.Int#' and `a'  Expected type: GHC.Prim.Int#  Inferred type: a     In the application `error ("cafRefs " ++ (showSDoc (ppr id)))' ----------------------------------------------------------------------------------------------   I modified the file to "import Err" and passed a "-i" command line option to get the compiler to see "err.hi-boot" in "libraries/base/GHC", but now I get (details at end of the email):   ---------------------------------------------------------------------------------------------- stgSyn/CoreToStg.lhs:18:     Something is amiss; requested module name Err differs from name found in the  interface file GHC.Err ----------------------------------------------------------------------------------------------   Is there an easy way around this (bootstrap?) problem?   I would also like some advice about how to interpret the initial error message about "#" and "*" if someone can point me in the right direction in the documentation.     Cheers   Mike Thomas   ------------------------------------------------------------------------------------------------------------------ /cygdrive/f/lang/ghc/ghcnl/bin/ghc -DGHCI -cpp -fglasgow-exts -Rghc-timing -I. -IcodeGen -InativeGen -Iparser -iutils:basicTypes:types:hsSyn:prelude:rename:typecheck:deSugar:coreSyn:specialise:simplCore:stranal:stgSyn:simplStg:codeGen:absCSyn:main:profiling:parser:usageSP:cprAnalysis:compMan:ndpFlatten:nativeGen:ghci  -package concurrent -package util -recomp -Rghc-timing -H16M '-#include "hschooks.h"' -O    -c stgSyn/CoreToStg.lhs -o stgSyn/CoreToStg.o   stgSyn/CoreToStg.lhs:1112:       Couldn't match `#' against `*'       When matching types `GHC.Prim.Int#' and `a'    Expected type: GHC.Prim.Int#    Inferred type: a       In the application `error ("cafRefs " ++ (showSDoc (ppr id)))'   <<ghc: 147694784 bytes, 78 GCs, 6234233/15873980 avg/max bytes residency (5 samples), 30M in use, 0.02 INIT (0.02 elapsed), 11.42 MUT (12.32 elapsed), 8.20 GC (8.37 elapsed) :ghc>>   make[2]: *** [stgSyn/CoreToStg.o] Error 1 make[1]: *** [all] Error 1 make[1]: Leaving directory `/e/cvs/fptools/ghc' make: *** [all] Error 1   ---------------------------------------------------------------------------------------------------------------------------- /cygdrive/f/lang/ghc/ghcnl/bin/ghc -DGHCI -cpp -fglasgow-exts -Rghc-timing -I. - IcodeGen -InativeGen -Iparser -i"e:/cvs/fptools/libraries/base/GHC" -iutils:basi cTypes:types:hsSyn:prelude:rename:typecheck:deSugar:coreSyn:specialise:simplCore :stranal:stgSyn:simplStg:codeGen:absCSyn:main:profiling:parser:usageSP:cprAnalys is:compMan:ndpFlatten:nativeGen:ghci  -package concurrent -package util -recomp -Rghc-timing -H16M '-#include "hschooks.h"' -O    -c stgSyn/CoreToStg.lhs -o stg Syn/CoreToStg.o   stgSyn/CoreToStg.lhs:18:     Something is amiss; requested module name Err differs from name found in the  interface file GHC.Err <<ghc: 28041516 bytes, 8 GCs, 1120992/2226000 avg/max bytes residency (2 samples ), 17M in use, 0.02 INIT (0.03 elapsed), 1.55 MUT (2.00 elapsed), 0.76 GC (0.77 elapsed) :ghc>> make: *** [stgSyn/CoreToStg.o] Error 1
