Description Johnny Hughes 2008-03-04 22:35:17 UTC 
Description of problem:
glibc-2.5-18.el5 and 2.5-18.el5_1.1 fail to build on sparcv9 and sparc64.

How reproducible:
Always

With all patches in place the following error occurs:

make -s subdir=nptl -C nptl ..=../ subdir_lib

This build is on the el5.0 code base with gcc-4.1.2- building el5.1.
(The el5.0 version of glibc-2.5-12 builds OK)

Rolling back the following patches allows glibc-2.5-18.x to build:

Patch108: glibc-ldso-locking1.patch
Patch109: glibc-ldso-locking2.patch
Patch122: glibc-rh295891.patch

After building with the patches rolled back, the tests (in the build process) of
this version are very similar to the tests of glibc-2.5.12.
Comment 1 Jakub Jelinek 2008-03-11 09:16:16 UTC 
Unlike Fedora development where we want the SRPMS buildable on SPARC, in RHEL I
have no intent to patch the src.rpms just to let CentOS/SPARC build without
patches.  You simply have to backport the relevant upstream SPARC patches to
make it work yourself.
Comment 2 Johnny Hughes 2008-03-11 14:15:56 UTC 
I can and will patch this to make it work for me ... I was just letting you know
that as released the source code is broken so that maybe on the next update
cycle you can roll in the applicable patch.

attached is the patch that fixes the problem
