The type of build you're attempting will not achieve the goal you're looking for. You will obtain a i586 toolchain, but the final system's triplet is determined by the output of config.guess. Since you're host system is a p4, and you're host distro probably has a i686 kernel, if you chroot you will end up with a i686 system. Pretty much what you want to happen is uname -m to report i586 instead of i686 so that when you compile the final system config.guess will report i586-pc-linux-gnu.
There's a couple of ways to go about doing this. The first one is to install a uname hack into the kernel. Which modifies the uts machine name to be whatever you want, in your case, i586. The second one is to wrap the uname program with a script or another program that modifies it's output. The third is to pass arguments to each and every package you want to build. I recommend the first one as it's the most transparent to the build. You just have to remember to remove the kernel module after you're done. This tarball contains the sources to work with 2.6 kernels before the uts namespace changes, (I believe pre 2.16): http://cross-lfs.org/~jciccone/uname_hack.tar.bz2 This source file works with kernels after the uts namespace changes (2.16 and on): http://cross-lfs.org/~jciccone/uname_ix86.c _______________________________________________ Clfs-support mailing list [email protected] http://lists.cross-lfs.org/cgi-bin/mailman/listinfo/clfs-support
