title: Getting `CXXABI_1.3.5' and `GLIBCXX_3.4.15' not found errors on RHEL6
body: <p>I am getting these errors on RHEL6 when trying to compile c++ code from github:</p>
  
  <p>/usr/lib64/libstdc++.so.6: version <code>CXXABI_1.3.5' not found
  /usr/lib64/libstdc++.so.6: version</code>GLIBCXX_3.4.15' not found</p>
  
  <p>I think I could install updates for these libs. However, my question is, would installing an update on these cause problems in the system somewhere if there are dependencies elsewhere? And if so, how could I work around this to use the newer versions of these libs?</p>
