Hello, You may have seen me working recently on a branch called 'jh'. I named it that as a way to show that there are personal changes that have not yet been community approved. And I needed an easy way to document and present ideas.
Here are the major changes: * Merge x86 and x86_64 commands into one book. Where there are textual explanations concerning target triplets, lib64 directories and dynamic linkers, I attempted to show what patterns to look for. Much of that, in fact, was already in the book. Commands to be executed, however, were made to work no matter which arch the host is. * Upgrade to HJL Binutils-2.17.50.0.18, GCC 4.2.1 and Glibc 2.6.1 (Since this book is targeted for 7.0, I decided to keep my work based on these current versions. The HJL Binutils so far seems to work better with these versions of GCC and Glibc.) * Use --disable-checking on GCC Pass 1. See this ticket: http://wiki.linuxfromscratch.org/lfs/ticket/2056 * Drop the Gcc specs patch in favor of a small loop. Because the loop is a little larger than most other modification commands, I explained it step-by-step afterwards, even though that would be unnecessary for the experienced reader. Additional educational value of the loop are two commands that are not elsewhere used in the book: 'cp -u' and find's '-o' switch. Missing items: * Need to fix up the command on the kernel page for installing the kernel. Will vary according to arch. Suggestions welcome. * Need to add a boot loader Items for future consideration: * Add --disable-stage1-checking for GCC Pass 1. Speeds up bootstrapping. The extra checking done on stage1 seems unnecessary, especially as it gets built again in two more stages of pass 1 and then our next two compilers are built in a known environment. * There's been a request to make '/tools' a variable. Incidentally, the libc patch to perl could also be swapped for command line alterations. Personally, even though there's often more typing, I favor these commands over patches. You can see at once what is being altered and there's greater opportunity for education. * For several of the packages in chapter 5 we could cut out the 'make install' target in favor of copying single binaries to /tools/bin, saving some measure of space. I haven't yet quantified the savings, so I don't know if this is worth the trouble, but it's an idea to consider. DIY does this for many of its packages already. The book has been verified to build on both x86_64 with 64-bit userspace and x86 hosts. As of now I only have logs for the x86 build. I intend to run builds again on both hosts running all final testsuites and either farce or ICA. Here's the rendered book: http://linuxfromscratch.org/~jhuntwork/lfs-JH/ And the x86 logs: http://linuxfromscratch.org/~jhuntwork/x86-logs/ That's it.
