Write a test program (name it for example glibc-version.c):
Copy#include <stdio.h>
#include <stdlib.h>
#include <gnu/libc-version.h>
int main(int argc, char *argv[]) {
printf("GNU libc version: %s\n", gnu_get_libc_version());
exit(EXIT_SUCCESS);
}
and compile it with the gcc-4.4 compiler:
Copygcc-4.4 glibc-version.c -o glibc-version
When you execute ./glibc-version the used glibc version is shown.

Running into a version `GLIBC_2.38' not found error
The program is too new for the distro. You're correct not to just "upgrade glibc". This is an integral part of the OS and difficult/impossible to do reliably. You could try running the program in a Distrobox using a distro which has a newer glibc, probably Fedora or Arch will work. You could wait until Kubu 24.04 and try there. It's already April so you could probably install the beta now and update to the full version when it comes out in a few weeks. More on reddit.com

For glibc:
/lib/libc.so.6
Sounds maybe strange to run a so file but should print out version information in this case
For the kernel version use uname
For the binutils parsing the output of ld --versionmight yield what you expect, the same for gcc --version. This is a bit tedious but I do not know another way.
