--- Comment #4 from Jignesh <j130496 at live dot co.uk> --- Again regarding glibc version: through command ldd -version the output is 2.33.9000 while through following script it is 2.28: Script for glibc version: #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); } Thank you.
