All of Gregs arguments appear to be rational. However, before I again make a decision based on someone else's research, and change the jh branch to something else, I'm going to be digging into this a little further. Although, I probably won't be able to really touch it until tomorrow night. Matt, as far as CFLAGS go, IIRC, glibc must be built with some level of optimization. If you set CFLAGS on the command line, I believe you're overriding what is included by default in the Makefile system, so you must also include some -O option in CFLAGS. -O2 is what Greg uses in DIY. I would think that it would be more ideal to find exactly what it is in the Glibc build system that defaults to i386 and change those defaults with a sed of some sort to be i486. Be warned that I'm just speaking from memory here. As I said above, I will be spending time digging so that I understand the whole system better, but if you get there first, great. Whoever commits this to trunk should understand thoroughly the issue - a mistake I admit I made with the jh branch. -- JH -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
