I've installed a version of Informix on Fedora Core3 designed for GLIBC v. 2.2.x
When I try and initialize the db I get the following error:
relocation error: /var/lib/libpthread.so.0: symbol _h_errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference

I found a post on the net that says to install a previous version of GLIBC:

Actually, You can try to install another GLIBC
package onto Your existing Linux.
For example, 'glibc-2.2.93-5.i686.rpm' works fine for IDS 9.21+

Here's my questions:
1. Is there another way to fix this other than installing an older
version of GLIBC (Currently I'm at 2.3) Here's an rpm query listing:
root@Issac # rpm -qa | grep -i glib
glibc-2.3.4-2.fc3
dbus-glib-0.22-10.FC3.2
glib-1.2.10-15
glibc-kernheaders-2.4-9.1.87
glibc-devel-2.3.4-2.fc3
glibc-common-2.3.4-2.fc3
glibc-headers-2.3.4-2.fc3
glib2-devel-2.4.8-1.fc3
glib2-2.4.8-1.fc3

2. If I have to install an older version of GLIBC can I add it as an addition
and only point the Informix files to use it?

3. If neither of the above questions are options, will I break my
system by reverting to an older version of GLIBC ?

Thanks in advance for your help.

You probably need to install the compat-glibc rpm's for older compatibility, etc.

Thanks for the info however it looks like the compat-glibc rpm's are designed to give one the ability to link to the older libs at compile time. What I need is the ability to point the informix binaries to a new set of shared libs at run time.

Will the compat-glibc rpm's do this for me?
