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

[Harris, James]

Hmmm, these had come to mind, but how would a program work that was
originally built against 2.1.9?  I didn't do the compat libs because I
percieved them as older even that what the app expected...?

On a positive note, so far the app seems to be OK.  'course, I'm worried
most about leaks and eventual problems... But I guess we'll just find out.
The vendor's official response was: "we don't support it."  So I guess we'll
either have to take our chances with the compat, never update a massively
exposed server, or update entirely from SRPM.

There are compatibility packages that come with the RH7 distro that you may
have overlooked: compat-glibc-6.2-2.1.3.2 & compat-libstdc++-6.2-2.9.0.14.
These packages are there specifically to address the problems you mention.

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!
