MRTrix3 error : version `GLIBCXX_3.4.26' not found [UNIX]

This solution works on Ubuntu

This happens when the Matlab provided versions of glibc are too old for MRTrix3, which here requires version 3.4_26.
You need to find if your computer has the right version somewhere, and if needed install it.
To check the versions that come with Ubuntu, type the following in the linux terminal:

(1) strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBC

This is where glibc is installed by default. If the needed version is not there, try:

(2) locate libstdc++

And test the command (1) for the different outputs of command (2).

If you did not find the required version anywhere, you need to install it, which I will not cover here.

Once you found the right version, keep its path, e.g. /usr/lib/x86_64-linux-gnu/ if you are lucky.

A first solution is to indicate that path in your module, which is done by writing the following below the "The core of the module starts here" lines in the module:

setenv('LD_LIBRARY_PATH', ['/usr/lib/x86_64-linux-gnu/:', getenv('LD_LIBRARY_PATH')]);

Another solution (not fully tested) could be to type in the linux terminal before launching matlab:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu/libstdc++.so.6

I think you can also write that in your .bashrc, but I did not test for it.
