Yes, if you develop on Ubuntu 22.04.1 then it won't run on CentOS 7.9. But you do the opposite, develop on CentOS 7.9 and run on Ubuntu 22.04.1 it will normally work.

Hi,
Thank you for your help.
I develop and successfully run my code on Ubuntu 22.04.1 LTS.
The OS of the production environment is CentOS 7.9.
Based on the information that you provide, I can only switch to a higher version of the Linux system as the OS in order to use the module I developed. Is my understanding correct?
Best regards,
Zhibang

主题: [SPAM] Re: Is there a minimum version requirement for glibc and GCC using EPICS
Hi,
In a general if you are running different versions of Linux on your systems, you have to compile the software on the
oldest OS version that you want to run it on. This isn’t an EPICS restriction, newer GLIBC versions contain compatibility code so that programs compiled against older versions can still run against it, but the reverse can’t be done. Using Maren’s example,
building your EPICS code on RHEL-5 should allow the result to also run on RHEL-6 and 7.
HTH,

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,
