Based on the documentation at http://www.gentoo.org/proj/en/base/amd64/technotes/install-32bit.xml, I expect emul-linux-x86-baselibs (or, barring that, emul-linux-x86-compat or emul-linux-x86-glibc) to create a symlink from /lib/ld-linux.so.2 to /emul/linux/x86/lib/ld-linux.so.2. Not only does this symlink not get created, but "find /emul/linux/x86 -type f -name ld\*" comes up completely empty, so no 32-bit ld-linux appears to be installed at all. Reproducible: Always Steps to Reproduce: 1.Install emul-linux-x86-{baselibs,compat,glibc} 2.Try to invoke a 32-bit app, or run "ldd" on said app. Actual Results: App fails on account of the lack of a 32-bit loader Expected Results: Ran (if invoked), or showed the libraries it was linked to (if not).

I find that I *do* have a /lib32/ld-linux.so.2, though not a /emul/linux/x86/lib/ld-linux.so.2. Attempting to exec 32-bit apps outside of their chroot still returns ENOENT.
this is already provided by glibc (not the emul-package, the native one) $ equery b /lib32/ld-linux.so.2 [ Searching for file(s) /lib32/ld-linux.so.2 in *... ] sys-libs/glibc-2.3.5-r2 (/lib32/ld-linux.so.2 -> ld-2.3.5.so) $ file /lib/ld-linux.so.2 /lib/ld-linux.so.2: symbolic link to `../lib32/ld-linux.so.2'
Then this is a documentation bug, as the linked docs clearly state that a symlink from /lib/ld-linux.so.2 will be created on installing the given packages.
sorry, you are right. the technotes are deprecated, and we're replacing it with newer, up to date documentation bit by bit. for the 32bit part, there is the chroot howto: http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=3 it's only about chroots, but the whole emul-linux-x86-* stuff is handled by portage anyway, so you don't have to care about it ;)
Created attachment 71584 [details, diff] General doc patch i've just completely re-read pretty all documentation i could find, and my conclusion is that we really don't need the technotes anymore. Beside removing links and so on, I also made minor changes to the other docs. Doc devs please review :)
CC'ing them to get more attention ;) /me is too impatient, I know, but this has been around for a pretty long period
Please let us (docs-team) know before you delete them, we have to fix metadocs before or it will be another massive screw-up.
Me and Gerald are working on it. We will ping docs teams about it before remove it.
Links to technotes from /doc/en/* files have been removed
Created attachment 71795 [details] /proj/en/base/amd64/technotes/index.xml You might want to replace the technotes index.xml with this one to avoid 404 errors and let users know where to go.
Leaving existing technotes on proj, with a note regarding deprecation, so that the old info can still be accessed while new section (Errata) and expansion of howtos takes place.
uhm, shouldn't we remove the link from proj/en/base/amd64/ to the technotes? i can't see a good reason to leave it there at least ;)

Okay, I'm going to commit this all, but I'm going to post what's on my todo list here first; I'd appreciate it if someone could tell me I've missed anything or whatever. 1. Commit blubb's attachment #71584 [details, diff] 2. Commit something like neysx's attachment #71795 [details] -- I think I'll just add a note to the start of the technotes, but not get rid of any of the content.
Tom, before you commit my patch, please let me have another look at it.. I just had a short look at it and found at least one typo (+ <p>We are continuouslylooking for volunteers willing to spend some of). As for the replacement, I agree, but there's already a fat "DEPRECATED" note on the top, so there's nothing to do :)
Created attachment 77291 [details, diff] removes technotes as far as technotes are concerned, this should do it.
technotes have been deprecated 6 months ago, all references to them were removed around that time too, except the one on our project page. removed that, together with the technotes themselves.
