downgrade glibc FC5

Hi, I am a newbie to LINUX world.

I have a clean Fedora 5 install working well. I need to downgrade the
glibc from 2.4 to 2.3.2 to have somw wanted applications work on it.

I have seen and tried rpm -Uvh --force glibc-2.3.6-3.i386.rpm glibc-common-2.3.6-3.i386.rpm glibc-devel-2.3.6-3.i386.rpm

but I received a long list of failed dependency of many application. Does that mean that I cannot downgrade this glibc on FC5 ?

Thanks for helping

Simple answer is that you don't want to. Downgrading glibc may well break much/all of your system. If you absolutely need these unnamed apps, and can't wait for the new versions that will work with your new glibc, then the way to install multiple versions of glibc is covered in this mailing list article from the redat website. Read the initial post, and all 3 responses, then you'll have the best way to go about it. Having 2 is ok, but downgrading your only copy would be an absolute nightmare.

Hello leshamal1,

You not specify what you want to run, but it is not needed to downgrade your glibc. And it is surely not something I can advice to do.

The best option is to install the following packages, which make glibc compatible with previous versions.


Simple run as root user, in your terminal "yum install compat-libgcc-296 compat-libstdc++-296 compat-libstdc++-33"

For most programs the "compat-libstdc++-33" package is enough.

Hem ... I did not manage to do it

1)I need to install the ic5141 software for integrated circuit design. it only
work with glibc-2.3.2 and my new fedora core 5 install has glibc-2.4-4 version.

I tried to have a rpm --prefix /libc glibc-2.4.4 to relocate the glibc-2.4.4 as mentionned in the post referred by Jim but the only answer I get is:

rpm: --prefix may only be used when installing new packages

2) Also I have seen another this post:

The easiest way is IMHO a minimal setup looking like this:

<somepath>/lib/ ->
<somepath>/lib/libc (and other needed libs)

...and then start it with something like:

$ LD_LIBRARY_PATH=<somepath>/lib <somepath>/lib/ <somepath>/bin/skype

uses LD_LIBRARY_PATH. Any feedback ? Anybody could guide me to do that ?

Thanks again
