Update glibc_2.12 to glibc_2.17 on Centos6

While installing tensorflow on Centos 6, the library linking error occured.

 

First, libstdc++ (CXXABI) related error (error message is as following) can be easily solved by compile and make new version of the library. 

ImportError: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.7' not found (required by /home/user/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so)

I followed the procedure in the page https://www.jianshu.com/p/f7cd0e2416b9

wget http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-5.4.0/gcc-5.4.0.tar.gz
tar -xvf gcc-5.4.0.tar.gz
cd gcc-5.4.0
mkdir build
cd build
../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
make && sudo make install
sudo ldconfig

Instead of changing the original library file of /usr/lib64/libstdc++.so.6, I simply added library path to environment variable to avoid library crash.

 LD_LIBRARY_PATH=/usr/local/lib64/:$LD_LIBRARY_PATH
 export $LD_LIBRARY_PATH

Second, for the libc error, I installed the 2.17 version using RPM to avoid library crash again.

sudo rpm -Uvh --force --nodeps glibc-2.17-55.el6.x86_64.rpm \

glibc-devel-2.17-55.el6.x86_64.rpm \
glibc-headers-2.17-55.el6.x86_64.rpm

"--force --nodeps" is added because of the dependency problem.

Available libray versions can be found by

strings /usr/lib/libstdc++.so.6 | grep ABI
