Checking which GNU C Library version
To check which GCLIB you are using run this small c program.
#include <stdio.h>
#include <gnu/libc-version.h>
int main(void) {
printf("GNU C Library version is %s\n", gnu_get_libc_version());
printf("GNU C Library release is %s\n", gnu_get_libc_release());
return 0;
}
// Example output from this command:
// GNU C Library version is 2.28
// GNU C Library release is stable
or this shell command
heth@mars:~/bin$ ldd --version
ldd (Ubuntu EGLIBC 2.19-0ubuntu6.6) 2.19
