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

Hi,

I have developed a modbus protocol based motor submodule in my own environment. It is successfully compiled and running without any issue in my development setup.

However, while migrating the module to the production environment, we encounter an error of low version library.

[hp@localhost iocLeadshine]$ ./st.cmd

../../bin/linux-x86_64/leadshine: /usr/lib64/libc.so.6: version `GLIBC_2.34' not found (required by ../../bin/linux-x86_64/leadshine)

The libc.so.6 can be found at directory /usr/lib64. It seems to be an issue that the glibc version is too low.

[hp@localhost iocLeadshine]$ strings /usr/lib64/libc.so.6 | grep GLIBC_

GLIBC_2.0

GLIBC_2.1

GLIBC_2.1.1

GLIBC_2.1.2

Is there a minimum version requirement for glibc when using the synApps/motor package?

We tried to compile the glibc from the source. But it is prompted that the gcc version is also not appropriate.

As a reference, here are the version of the packages in the production environment.

EPICS base 3.15.9

asyn R4-41

seq 2-2-5

busy R1-7

modbus R3-2

motor R7-1
