I used to have a NPTL glibc on this sparc system, but now (after upgrading linux26-headers) I wanted to recompile glibc. It fails with the following error: [Mon Jan 17 10:53:34 root@blackbox ~]# emerge -Dav glibc These are the packages that I would merge, in order: Calculating dependencies ...done!

If you need support, post the topmost build error, NOT this status message. is this nptl-related? and if the answer is yes, is nptl working on sparc? should I revert to non-nptl and (possibly) linux 2.4 headers?

i'll update the glibc ebuild then to remove sparc from the nptl list i doubt any of the sparc guys are interested in tracking nptl atm
This is specific to 3.3.5-r1. 3.3.4 and the 3.4.x work fine...
In 3.3.4-r2 (and others before it), lv used a redhat snapshot which backported some work from 3.4. This included some patches that got tls working on sparc. In 3.3.5{,-r1} lv used mainline over redhat, so those patches were lost. I'm making a new 3.3 release with an updated mainline and reintegrating those fedora changes. You can get it from http://dev.gentoo.org/~eradicator/gcc I'm just waiting on some pie updates from Peter before I add it in, so if you want to test it, you need to disable the pie patches.
I would gladly try the fix, but last night the hard disk decided to die, and I'm waiting for a replacement, so I'm stuck now. I will try it ASAP, thanks for the fix.
Fixed in portage. 3.3.5.20050130 (~sparc).
