Both your links are the same... I'm not opposed to adding some optimization into LFS. We are, after all, not building for a lowest capability system but we are targeting a custom system for each user. That said, the discussion of optimization needs to be changed in the Intro section to Chapter 6. It now says: "Also note that the -march and -mtune options may cause problems with the toolchain packages (Binutils, GCC and Glibc). The small potential gains achieved in using compiler optimizations are often outweighed by the risks. First-time builders of LFS are encouraged to build without custom optimizations. " This seems to be at odds with the above. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
