[lug] Compatibility between glibc-2.1 and glibc-2.2

[Harris, James]

Hi everybody!

I'm getting confused with the recent RedHat updates on RH 7.0 bringing
glibc-2.1 up to glibc-2.2.  We have a box that we've patched completely, but
our third party application was apparently linked against 2.1 and won't
install now that we have 2.2.4 on the system.

Looking at the install script, we can easily fool the installer to work, but
the BIG question is: will be application be unstable running with 2.2 when
it was originally built on 2.1?  We've sent this question out to the vendor,
but anticipate that it may take them some time to respond, and I figure you
guys might know whether the glibc libraries themselves are compatible.  I've
tried going to the glibc web page but can't find any compatibility
information out there.

Does anyone here know?... Or are there any good sites out there that address
this type of compatibility issue?

Thanks as always!
