Link statically to libstdc++ with -static-libstdc++ gcc option.

Here's a solution for this problem in Ubuntu 16.04

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo apt-get upgrade libstdc++6

You can check if you get GLIBCXX desired version like this:

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

I got a very similar issue, and solved it by linking the the lib file into the conda environment. For your situation you may try something like this:

ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /home/anavani/anaconda3/envs/dmcgb/bin/../lib/libstdc++.so.6

The errors are caused by a mismatch between the libstdc++ library shipped with Ubuntu 22.04 and MATLAB R2022b. Refer to the following link for the supported and compatible compilers for current and previous versions: https://www.mathworks.com/support/requirements/supported-compilers-linux.html As a workaround, you can direct MATLAB to use the system's libstdc++ library rather than the MATLAB shipped version. This can be achieved by setting the following environment variable prior to starting MATLAB: LD_PRELOAD=/lib/x86_64-linux-gnu/libstdc++.so.6 matlab You can then force load the system libstdc++ with the expected GLIBCXX version. Note that the above command only sets the environment variable for MATLAB. To set it for other processes of the current shell, use the following commands instead: export LD_PRELOAD=/lib/x86_64-linux-gnu/libstdc++.so.6 matlab If the above solution does not help and you get an error similar to the following .MathWorks/ServiceHost/-mw_shared_installs/v2024.9.0.2/bin/glnxa64/MathWorksServiceHost: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by ........) This error basically means that the 'libstdc++' library version shipped with the MathWorks ServiceHost has higher version than the system 'libstdc++' library. Please use one of the following mentioned steps to resolve the issue: 1. Upgrade the system 'libstdc++' library version to a newer version and set 'LD_PRELOAD' to point to this library as mentioned above. 2. Change the 'LD_PRELOAD' path to point to the MathWorks ServiceHost library as follows: LD_PRELOAD=~/.MathWorks/ServiceHost/-mw_shared_installs/VERSION/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6 matlab And, to set it for other processes of the current shell, use the following commands: export LD_PRELOAD=~/.MathWorks/ServiceHost/-mw_shared_installs/VERSION/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6 matlab Where 'VERSION' is the latest version of MathWorks ServiceHost matching your current MATLAB Version. For e.g, if you are using MATLAB R2024a, your ServiceHost version would like 'v2024.9.0.2'.

Installing libstdc++6 and gcc-9 helped me. Hope it will help you too.

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-9
sudo apt install libstdc++6

What is libstdc++.so.6? Is this just a library that gcc ships with?

It’s GCC’s implementation of the C++ Standard Library.

What are all the different GLIBCXX_*? Are these also libraries?

These are version symbols, used to allow the library to remain backward-compatible while still being able to change its API. See What do the multiple GLIBC versions mean in the output of ldd? for details.

Question is why do I have different versions of these libraries in different folders?

The copy in /usr/lib64 is your distribution’s version; the copy in /usr/local/lib64 was installed by something else.

When running gcc how do I tell it to use the 6.0.20 library in /usr/local/lib64 instead of the older one?

You can try building with -L/usr/local/lib64, and running with LD_LIBRARY_PATH=/usr/local/lib64 (if necessary).

Don't download random binaries hoping they will work on your system.

Just been tackling a similar problem, it looks like you need to ensure you have the latest version of gcc. Running:

conda install -c conda-forge gcc=12.1.0

Fixed the error for me.
