How do you upgrade GLIBC?
 
How can you upgrade glibc without upgrading every other package on the computer? I need to upgrade gcc, but it takes a new glibc. So, what do I do? I'm using RedHat 7.2. I can't upgrade Redhat. How do I upgrade glibc without breaking dependinces?

How do I upgrade glibc without breaking dependinces?
Glibc libraries are essential for having Linux work properly, so what you're asking is something like asking how to renovate the foundation of a building without moving the structure on top of that first.

Warning: I used the next procedure with some libs but never with Glibc tho, so YMMV(VM). If you feel upgrading Glibc will be like doing open heart surgery, make a backup first and have a rescue CD/floppy ready, Justin Case. Make a local copy of /etc/ld.*. Copy the Glibc libraries to a new dir, call it /usr/lib_old or so. Add that path in /etc/ld.so.conf. Run ldconfig and check if it's added the path. Now remove the original Glibc path from /etc/ld.so.conf and update running ldconfig. You'll find out if this will work soon enough :-]
If it works, test upgrading Glibc. If satisfied, install. Check if old apps still work.

My experience has been that glibc is backwards compatible, so you shouldn't have anything to worry about.

Wynd, I'm glad it's always been smooth
for you, but rest assured that this is NOT
the normal thing to happen :) I've had two
disasters in the past, and the only time I
upgraded glibc with no hassle was when
upgrading the entire system from Slack 8.0
to 8.1 ;)

I'd go with unspawn and say "Very cautiously!"

Cheers,
Tink
