I upgraded glibc for a reason that isn't arround anymore so i want to downgrade it again. The stupid thing is a lot of programms rely on glibc at the moment. I still have the 2.4 version on the system as the command below shows, but i'm not able to delete the 2.9 version.

# rpm -qa|grep  glibc

I've tried rpm -e glibc-2.9-2.9 but the system just tells me that a huge amount of stuff depends on glibc. So I was wondering if I can somehow set the 2.4 version to default or so and then remove the 2.9 version.

plus now i think it has something to do with this other problem i'm having stackoverflow.com/questions/7675725/… –  almightyBob Oct 6 '11 at 14:25
you don't have glibc-2.4-2.4 installed from the list of packages you showed. If you remove the 2.9 version your system won't have a glibc library anymore, which is bad. I guess your programs are not working because you have some glibc-* package at version 2.4 and some other at version 2.9. Did you install version 2.9 from package manager or from a custom rpm? –  pqnet Aug 27 at 9:10

There are much simpler ways to downgrade the glibc as well. For example, yum will calculate all of the needed dependencies for you with a

yum downgrade glibc\* 

command. But beware: downgrading glibc is always a really dangerous trick, and it is so on every system.

Glibc on version 2.4 and 2.9 had already very good compatibility between them, I suggest for you the best option were is your 2.9 left.
