You'll probably need to recompile gmp, which optimises itself to the architecture it's built on. I once transferred a set of LFS Chapter 5 tools from a desktop machine with an Intel Core Duo to a laptop with a Via Nano, and I got a lot of apparently random segfaults through the early stages of chapter 6. No one could tell me why. But once I had a full local set of primary compilation tools, the crashes stopped. -- -- http://lists.linuxfromscratch.org/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
