Hi Guys, I'm trying to rebuild ghc 6.8.3 (the previous version was built without readline linked in), and I'm running into a compilation issue. build error: /lusr/bin/ghc -#include cutils.h -DSTAGE=1 -package-name ghc-6.10.1 -hide-all-packages -no-user-package-conf -package-conf /v/filer4b/cvsbuild/CVSBUILD/ghc-6.8.3-linux-i686/ghc/libraries/bootstrapping.conf -i -idist-stage1/build -inativeGen -ibasicTypes -icmm -icodeGen -icoreSyn -icprAnalysis -ideSugar -ighci -ihsSyn -iiface -imain -iparser -iprelude -iprofiling -irename -isimplCore -isimplStg -ispecialise -istgSyn -istranal -itypecheck -itypes -iutils -ivectorise -idist-stage1/build/autogen -Idist-stage1/build/autogen -Idist-stage1/build -Istage1 -I../libraries/base/cbits -I../libraries/base/include -I. -Iparser -Iutils -optP-include -optPdist-stage1/build/autogen/cabal_macros.h -odir dist-stage1/build -hidir dist-stage1/build -stubdir dist-stage1/build -package Cabal-1.6.0.1 -package array-0.1.0.0 -package base-3.0.2.0 -package bytestring-0.9.0.1.1 -package containers-0.1.0.2 -package directory-1.0.0.1 -package extensible-exceptions-0.1.0.0 -package filepath-1.1.0.1 -package haskell98-1.0.1.0 -package hpc-0.5.0.2 -package old-time-1.0.0.0 -package process-1.0.0.1 -package unix-2.3.0.1 -O -Wall -fno-warn-name-shadowing -fno-warn-orphans -XPatternSignatures -XCPP -XMagicHash -XUnboxedTuples -XPatternGuards -XForeignFunctionInterface -XEmptyDataDecls -XTypeSynonymInstances -XMultiParamTypeClasses -XFlexibleInstances -XRank2Types -XScopedTypeVariables -XDeriveDataTypeable -idist-stage1/build -H32m -O -Rghc-timing -c types/Unify.lhs -o dist-stage1/build/Unify.o -ohi dist-stage1/build/Unify.hi parser/Lexer.x:1652:17: Not in scope: data constructor `SLIT' parser/Lexer.x:1653:23: Not in scope: data constructor `SLIT' <<ghc: 351226848 bytes, 20 GCs, 3982677/8409088 avg/max bytes residency (3 samples), 36M in use, 0.00 INIT (0.00 elapsed), 0.32 MUT (0.37 elapsed), 0.12 GC (0.13 elapsed) :ghc>> make[2]: *** [dist-stage1/build/Lexer.o] Error 1 make[2]: *** Waiting for unfinished jobs.... <<ghc: 236588812 bytes, 17 GCs, 4490581/8404992 avg/max bytes residency (3 samples), 36M in use, 0.00 INIT (0.00 elapsed), 0.49 MUT (0.57 elapsed), 0.15 GC (0.15 elapsed) :ghc>> make[1]: *** [build.stage.1] Error 2 make: *** [stage1] Error 1 I've hit up google and the only results which stood out were other "data constructor not in scope" messages which were due to people trying to run old haskell code using newer versions of the compiler, but I doubt that's the case here as I am using the same version of the compiler as both host and target. Any ideas? -jason
