I updated my gcc to 4.9+ while there's no GLIBCXX_3.4.20
in /lib64/libstdc++.so.6
, and it encounters error: version GLIBCXX_3.4.20 not found
.
In the new gcc I installed locally, I can find gcc_installed/lib64/libstdc++.so.6.0.20
, but is there any method to update the libstdc++ without root? Or alternative way to handle this problem?
