Re: Is there a minimum version requirement for glibc and GCC using EPICS

[Maren Purves via Tech-talk <tech-talk at aps.anl.gov>]

What is your operating system (in both systems)?

We (running CentOS5, 6, or 7), on different machines, some of which
probably aren't upgradable) have run into (not EPICS related, this is
for Chrome - none of the CentOS5 machines have Chrome, they're older
processing computers) :

Failed to build transaction:
google-chrome-stable-131.0.6778.204-1.x86_64 requires
libc.so.6(GLIBC_2.25)(64bit)

but installing that libc version would break the operating system on
those machines, so before you install a newer version of libc.so to
what it says you need you would have to check whether that would
require an operating system upgrade or possibly break the current one.

HTH, and aloha,
