rpm install in CentOS6 does not recognize dynamic library libc.so.6

Question

I'm new to rpm and cannot find a way to get it to recognize .so files in /usr/lib, it cannot find libc.so.6 which is there. Is this related to the rpm build process or something I can perhaps modify. The man page did not have anything which appeared related to dynamic or libraries, which I believe the .so file to be.

rpm -ivh libusbx-1.0.16-1.fc20.i686.rpm 
error: Failed dependencies:
libc.so.6(GLIBC_2.17) is needed by libusbx-1.0.16-1.fc20.i686
libudev.so.1 is needed by libusbx-1.0.16-1.fc20.i686
libudev.so.1(LIBUDEV_183) is needed by libusbx-1.0.16-1.fc20.i686

Looking at the commands in the window below, does this mean that there is no libc.so.6 and if so what might have created the links?

$ ll /usr/lib/libc.so.6
lrwxrwxrwx 1 root root 14 Jul 13 17:26 /usr/lib/libc.so.6 -> /lib/libc.so.6
$ ll /lib/libc.so.6
lrwxrwxrwx 1 root root 12 Jul 12 20:01 /lib/libc.so.6 -> libc-2.12.so

Most importantly is there a safe way to update libc.so.6 on Centos 6.3 that will not somehow brick the box, as this dynamic library looks important. I did just update to glibc_2.17 which was part of a Fedora build, but I had this issue below so I'm thinking it's unrelated.

Answer 1

/lib/libc.so.6 -> libc-2.12.so

This means that you have glibc-2.12

libc.so.6(GLIBC_2.17) is needed by libusbx-1.0.16-1.fc20.i686

The libusbx package requires glibc-2.17. Your distribution is too old.

is there a safe way to update libc.so.6 on Centos 6.3

I could be wrong, but usually RedHat EL distributions (and CentOS based on them) do not allow you to upgrade glibc via standard update mechanisms.

And you are rightfully concerned about an update causing "bricked" system; whatever you do, proceed with extreme caution.
