You left the toplevel gcc directory lying about after the earlier build. Delete it completely, then unpack the original tarball and start again from scratch. That applies to all packages btw. In chapter 6, you will build again many packages that you already built in chapter 5. Don't build any of them in stale directories. Always delete completely, then untar. -- -- 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.
