Though I have reported some sort of success on this in the last days, I was too early. The ghc-inplace does not work on the target system. It compiled because I have been too lax in following the instructions. Here is the report, where the crossport fails on the i386host system: tar czf ghc-6.4.1-x86_64-unknown-freebsd-hc.tar.gz `cat hc-files-to-go` tar: ghc-6.4.1/ghc/rts/PrimOps.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/ghc/rts/StgStartup.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/ghc/rts/StgStdThunks.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/ghc/rts/Updates.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/ghc/rts/Apply.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/ghc/rts/Exception.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/ghc/rts/HeapStackCheck.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/ghc/rts/StgMiscClosures.hc: Cannot stat: No such file or directory tar: ghc-6.4.1/libraries/haskell-src/Language/Haskell/Parser.hs: Cannot stat: No such file or directory gmake: *** [hc-file-bundle] Fehler 1 bash-2.05b$ (cd ghc/rts; gmake PrimOps.o ) ../../ghc/compiler/ghc-inplace -H16m -O -H32m -keep-hc-files -static -I. -#include Prelude.h -#include Rts.h -#include RtsFlags.h -#include RtsUtils.h -#include StgRun.h -#include Schedule.h -#include Printer.h -#include Sanity.h -#include STM.h -#include Storage.h -#include SchedAPI.h -#include Timer.h -#include Itimer.h -#include ProfHeap.h -#include LdvProfile.h -#include Profiling.h -#include Apply.h -fvia-C -dcmm-lint -c PrimOps.cmm -o PrimOps.o In file included from PrimOps.cmm:28: /home/wb/Haskell/fptools-i386amd64/ghc-6.4.1/ghc/includes/Cmm.h:288:2: #error mp_limb_t != StgWord: assumptions in PrimOps.cmm are now false gmake: *** [PrimOps.o] Fehler 1 Similar messages for attemps to make other of the failing .hc files. Perhaps crossporting from a 64bit system is easier. I presume that once a working ghc is available, life is much easier, as Fedora Linux-64 does not report problems. -- Dipl.-Math.
