RHEL 6 Update GLIBC 2.12 to GLIBC 2.17

This often occurs when you build software in RHEL 7 and try to run on RHEL 6.

To update GLIBC to any version, simply download the package from

https://ftp.gnu.org/gnu/libc/

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz
2. cd glibc-2.14
3. mkdir build
4. cd build
5. ../configure --prefix=/opt/glibc-2.14
6. make
7. su
8. make install
9. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

Then try to run your software, glibc-2.14 should be linked.
