The 32-bit version came from the defaults on your host system. I am not sure if knoppix includes a 6-bit compiler ? If it does, using -m64 might allow you to build 64-bit binaries. From memory, knoppix is slimmed down - I see from the cheat codes https://translate.googleusercontent.com/translate_c?depth=1&hl=en&prev=search&rurl=translate.google.co.uk&sl=de&u=http://knoppix.net/wiki/Cheat_Codes&usg=ALkJrhjL7MCIqAa2rg0dL4xnjr4s0WpILg that knoppix64 boots a 64-bit kernel, but it says nothing about whether userspace is also 64-bit. In the past, on multilib systems, exec'ing 'linux32' or 'linux64' (as root) would change the environment [ I used to use that to build 32-bit ppc on a ppc64 ], but that will only work if everything is present. In particular, you need the 64-bit libraries. Those might be in /lib64, or they might be in /lib with the 32-bit in /lib32. I find it odd that an x86 system which reports it is x86_64 would default to building 32-bit programs, but apparently it does. The /tools/bin/ld binary comes from pass 2 ad looks good. But building on an x86_64 host system which defaults to 32-bit binaries is an unexplored situation. You did not mention how the other files look. If glibc is 64-bit then I suppose you could try adding -m64 to your CFLAGS when you compile. But I do not know if that will work (as always you need freshly extracted source), and if it does I don't know if you will be able to complete chapter 5 doing that. ĸen -- This email was written using 100% recycled letters. -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
