Hi Hazel, googling for a couple of random tests in that list found failures in the release notes for glibc-2.26, which I think you are using, and glibc-2.27. But they were all on other architectures. > I've never had so many failures before.

I suspect we removed that text because nobody who follows the dev list has non-intel non-AMD x86 CPUs these days. > > Do I need to rebuild and, if so, can anyone suggest what parameters I might > need to use to avoid a repetition? The proof of the pudding is in the eating! Probably very few people, if any, are using this CPU to build and test packages such as glibc. Usually, a test failure does not cause any noticeable problems at runtime. I would suggest you continue. ĸen > -- > Hazel Russman > -- > http://lists.linuxfromscratch.org/listinfo/lfs-support > FAQ: http://www.linuxfromscratch.org/blfs/faq.html > Unsubscribe: See the above information page > > Do not top post on this list. > > A: Because it messes up the order in which people normally read text. > Q: Why is top-posting such a bad thing? > A: Top-posting. > Q: What is the most annoying thing in e-mail? > > http://en.wikipedia.org/wiki/Posting_style -- Keyboard not found, Press F1 to continue -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
