Ubuntu – version `GLIBCXX_3.4.21′ not found

MATLAB

I am using Matlab for ubuntu R2014a and I am not able to run a code because I get the following error

/usr/local/MATLAB/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6:version 'GLIBCXX_3.4.21' not found

when I run:

$ strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBC
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3

GLIBCXX_3.4.5
GLIBCXX_3.4.6

Actually I figured out what was wrong, as my system was GCC 5.2.1,

the file /usr/local/MATLAB/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6 was designed for GCC 4.4.X so Matlab was actually picking the wrong file. I just made a symbolic link to my system's libstdc++.so.6 using this on terminal -

ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/local/MATLAB/R2014a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6
