Reproduce: # ldconfig -v 1>/dev/null ldconfig: Path `/usr/lib' given more than once Observation: libstdc++-2.96-81 postinstall script does echo /usr/lib >>/etc/ld.so.conf but I'm guessing that path is already hard coded into glibc? Hack: remove /usr/lib from /etc/ld.so.conf Is that a safe thing to do?
It is not error, it is a warning and only printed with -v. If you want ldconfig verbose, then it is really verbose. I don't consider this a bug at all.
