Rebuilding glibc: still pull in current's version?


I would like to rebuild glibc on my Raspberry Pi 1 following the guide linked to in the sticky post here. However, the very first commands involve pulling in the glibc version from slackware-current. My Slackware 14.1 installation on the Pi has glibc-2.17, while the slackware-current glibc is now version 2.23.

Can I upgrade the glibc version in the process of rebuilding, or will this lead to breakage?

You can upgrade, downgrade will break everything that was compiled against newer version.

Thanks, the upgrade worked and the Pi runs fine, maybe a little faster.

The linked tutorial didn't work for me without some tweaking, however. To avoid the build process complaining that the rsync'ed kernel-headers were too old (when they were the same version as the installed kernel), I had to edit the glibc.Slackbuild and tell it to use the kernel headers in /usr/include. Of course, before that I had to install the kernel-headers package from Slackware-current.

@CRCulver, I am the author of that guide. You might wish to post a comment explaining what you tweaked and how. I always welcome constructive feedback, even (especially) when I post some bad info. ;-)

(Addendum: I have comment approval turned on, and no Internet at home, so your comment might not appear for a few days.)

the link to slackkit 1.04 is old, the current appears to be:
http://mirrors.vbi.vt.edu/linux/slac...1.05-arm-1.txz

When I try to arm/build I get

Code:
Extracting Linux Kernel headers into /root/tmp/build-glibc
tar: /root/slackwarearm-current/source/l/glibc/../../d/kernel-headers/sources/kernel-headers-4.4.8.tar.xz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
  glibc-2.23-arm-3.txz.build.log:  3.361:1,  2.380 bits/byte, 70.25% saved, 2773 in, 825 out.
Where is 4.4.8 specified, within slackkit?
