Thank you for your reply.

I understood that the path of the library was not ok.

I think that I succeed to solve by specifying the exact adress of the library but now I have another error.

Error using mex

/usr/bin/ld: /usr/local/MATLAB/R2024a/bin/glnxa64/libstdc++.so.6: __cxa_thread_atexit_impl: invalid needed

version 54

/usr/bin/ld: /usr/local/MATLAB/R2024a/bin/glnxa64/libstdc++.so.6: error adding symbols: bad value

collect2: error: ld returned 1 exit status

This error occurs for both matlab 2019 and 2024. Can you help me?

I got exactly the same problem, could someone help with this?

Hey @Remi Choquet

It seems that the operating system's version of "libstdc++" and the version being used by MATLAB are different. Here is something you could try: when starting MATLAB, use the following command in the Bash shell:

LD_PRELOAD=matlabroot/bin/glnxa64/glibc-2.17_shim.so application

Here, "matlabroot" is the MATLAB installation path, and "application" is the original command that generated the error message.
