Sure enough I did. As I said, I carefully followed the instructions. I repeated the whole process 3 times to make sure I didn't forget something :)
So could you check the values of SIZEOF_VOID_P (in ghcautoconf.h) and SIZEOF_mp_limb_t (in DerivedConstants.h)? They should both be 8 in the versions of these files copied from the target.
Aha. The values are different. Carefull watching of the DerivedConstants.h showed that it was overwritten when I did 'cd H/ghc && make boot'. And yes, I did touch of all the copied files.
Even worse. This file gets overwritten on subsequent steps as well. So, my attempts to copy the correct one from the T machine again and again fail.
Ok, looks like I need to update the instructions. Does this sequence work:
- cd H/ghc/includes && make boot - copy files from T/ghc/includes to H/ghc/includes - touch the files - cd H/ghc/includes && make <<-- should do nothing now
Nope. It does not. The last step still recreates DerivedConstants.h
Well, looking at the makefile it becomes clear, that it must do so. ------------------------------------- # Make DerivedConstants.h for the compiler all :: DerivedConstants.h mkDerivedConstants.c : $(H_CONFIG) mkDerivedConstantsHdr : mkDerivedConstants.o $(CC) -o $@ $(CC_OPTS) $(LD_OPTS) mkDerivedConstants.o DerivedConstants.h : mkDerivedConstantsHdr ./mkDerivedConstantsHdr >$@ CLEAN_FILES += mkDerivedConstantsHdr$(exeext) DerivedConstants.h ------------------------------------ Since ghcautoconf.h is new this triggers update for mkDerivedConstants.c which in turn updates mkDerivedConstantsHdr which in turn updates DerivedConstants.h. I guess I should also touch the mkDerivedConstants.c to avoid the updates. Am I correct? -- Minds, like parachutes, function best when open
