I just implemented this and it seems to work as you described. However, I wasn't sure what you wanted the default behavior to be. My personal preference would be to default to 2.6.9 (or whatever) rather than the kernel headers version simply so people don't do what I did and have to rebuild since their toolchain was unusable for them. But since it is just a default setting after all, I don't have a strong opinion on it. Let me know and I'll send the updated patch. > Is there a good reason why 2.6.9 is a _sane_ default over other > versions? Admittedly, it was somewhat arbitrary :) But the reason I chose 2.6.9 was: 1) It's old enough that most people are probably targeting kernels newer than it 2) It's new enough that it wouldn't burden glibc with too much legacy cruft 3) So why not 2.6.8 or 2.6.12 ? Well, most importantly, Gentoo builds glibc with --enable-kernel=2.6.9 in its ebuilds :) Therefore, I declared 2.6.9 to be sane :) The old crosstool used 2.6.4 for NPTL builds and 2.4.3 for non-NPTL, for what it's worth. -- Nate Case <ncase@xes-inc.com> -- For unsubscribe information see http://sourceware.org/lists.html#faq
