I'm continuing in my quest to produce a clean build of GHC for Mac intel. I'm using registerised .hc files built on 386 linux. I suspect today's problem is pretty easy to figure out for a GHC expert, but I'm not. When I try to build utils/genapply, the link fails because the symbols _GHCziList_lvl22_closure and _GHCziList_zdwlen_info are undefined. I'll include the build log below. While we're on the topic, can somebody explain the algorithm used to generate these symbol names? The build log was: gcc -x c GenApply.hc -o GenApply.raw_s -S -O -fno-builtin -fno-defer- pop -fomit-frame-pointer -mdynamic-no-pic - DDONT_WANT_WIN32_DLL_SUPPORT -mdynamic-no-pic - D__GLASGOW_HASKELL__=605 -O -I/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/includes -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/base/include -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/unix/include -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/parsec/include -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/readline/include -I. `echo | sed 's/^$/- DSTOLEN_X86_REGS=4/'` ../../driver/mangler/ghc-asm GenApply.raw_s GenApply.s as -o GenApply.o GenApply.s gcc -o genapply -fno-builtin -fno-defer-pop -fomit-frame-pointer - mdynamic-no-pic -DDONT_WANT_WIN32_DLL_SUPPORT -mdynamic-no-pic - D__GLASGOW_HASKELL__=605 -O -I/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/includes -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/base/include -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/unix/include -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/parsec/include -I/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/ libraries/readline/include -L/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/rts -L/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/rts/ gmp -L/Users/rfh/ghc-6.5/mac/ghc-6.5.20060510/libraries/base -L/Users/ rfh/ghc-6.5/mac/ghc-6.5.20060510/libraries/base/cbits -L/Users/rfh/ ghc-6.5/mac/ghc-6.5.20060510/libraries/haskell98 -L/Users/rfh/ghc-6.5/ mac/ghc-6.5.20060510/libraries/parsec -L/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/libraries/Cabal -L/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/libraries/template-haskell -L/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/libraries/readline -L/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/libraries/unix -L/Users/rfh/ghc-6.5/mac/ ghc-6.5.20060510/libraries/unix/cbits -u "_GHCziBase_Izh_static_info" -u "_GHCziBase_Czh_static_info" -u "_GHCziFloat_Fzh_static_info" -u "_GHCziFloat_Dzh_static_info" -u "_GHCziPtr_Ptr_static_info" -u "_GHCziWord_Wzh_static_info" -u "_GHCziInt_I8zh_static_info" -u "_GHCziInt_I16zh_static_info" -u "_GHCziInt_I32zh_static_info" -u "_GHCziInt_I64zh_static_info" -u "_GHCziWord_W8zh_static_info" -u "_GHCziWord_W16zh_static_info" -u "_GHCziWord_W32zh_static_info" -u "_GHCziWord_W64zh_static_info" -u "_GHCziStable_StablePtr_static_info" -u "_GHCziBase_Izh_con_info" -u "_GHCziBase_Czh_con_info" -u "_GHCziFloat_Fzh_con_info" -u "_GHCziFloat_Dzh_con_info" -u "_GHCziPtr_Ptr_con_info" -u "_GHCziStable_StablePtr_con_info" -u "_GHCziBase_False_closure" -u "_GHCziBase_True_closure" -u "_GHCziPack_unpackCString_closure" -u "_GHCziIOBase_stackOverflow_closure" -u "_GHCziIOBase_heapOverflow_closure" -u "_GHCziIOBase_NonTermination_closure" -u "_GHCziIOBase_BlockedOnDeadMVar_closure" -u "_GHCziIOBase_Deadlock_closure" -u "_GHCziWeak_runFinalizzerBatch_closure" -u "___stginit_Prelude" GenApply.o -lHSreadline -lHStemplate-haskell -lHSunix - lHSunix_cbits -lHSCabal -lHShaskell98 -lHSbase -lHSbase_cbits - lHSparsec -lHSrts -lgmp -lm -lreadline -lncurses -ldl /usr/bin/ld: Undefined symbols: _GHCziList_lvl22_closure _GHCziList_zdwlen_info collect2: ld returned 1 exit status make[1]: *** [genapply] Error 1 Reilly Hayes
