Mex compiling on 64 bit linux - /usr/bin/ld: cannot find -lstdc++

Question

Okay I am trying to compile a mex file on 64 bit linux, ubuntu to be precise with Matlab 2013a.

First it gave a error that it could not find GLIBCXX_3.4.15

Answer 1

Same problem here on Ubuntu 13.04 using MATLAB 2013a. I solved it doing:

sudo mv /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6 /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6.old

To keep a backup just in case.

And then a symbolic link:

sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.17 /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6
