Hi Jim,

Here is an answer from the "Frequently Asked Questions about the GNU C Library" (the FAQ):
4.9.	How can I find out which version of glibc I am using in the moment?

{UD} If you want to find out about the version from the command line simply
run the libc binary.  This is probably not possible on all platforms but
where it is simply locate the libc DSO and start it as an application.  On
Linux like


This will produce all the information you need.

What always will work is to use the API glibc provides.  Compile and run the
following little program to get the version information:

#include <stdio.h>
#include <gnu/libc-version.h>
int main (void) { puts (gnu_get_libc_version ()); return 0; }

This interface can also obviously be used to perform tests at runtime if
this should be necessary.
BTW: the "{UD}" in that FAQ entry is the initials of the author. But don't contact Ulrich Drepper till you have tried everything in his FAQ entry first.
