Has issue with libstdc++.so.6 been fixed?

I have the impression that the issue with libstdc++.so.6 has been fixed for recent MATLAB releases, because I cannot reproduce the problem anymore with MATLAB 9.14.0.2489007 (R2023a) Update 6. I'm using the procedure described in another question which is expected to produce the error.

I'm running the following command in MATLAB

spatial = py.importlib.import_module('scipy.spatial')

this works without any need for setting LD_PRELOAD in R2023a Update 6 on my system. Has the problem with libstdc++.so.6 been fixed recently?

For context: I'm actually investigating this issue, but I think this makes it much harder to reproduce the problem and I hope that falling back to importing scipy.spatial is a valid simplification.

Hi Benjamin,

i'm using the R2024a Version an still encounter this issue. I run MATLAB on a Linux system (Ubuntu 22.04.2). Since this problem may depent on the operating system your'e using, may i ask you what kind of OS you're using?

Hi Sven,

I was still using Ubuntu 20.04.x when I posted this questions if I remember correctly (not sure about the last digit of the version). I've moved to Ubuntu 24.04 in the meantime but did not install MATLAB yet on my new system yet.

Hi Benjamin,

In the past, MATLAB users frequently encountered issues when trying to use Python functionalities that depended on newer C++ libraries, due to MATLAB's reliance on an older version of “libstdc++.so.6”. This is a known issue for MATLAB as there were similar questions before which were answered by MathWorks’s staff. So, this is a strong indication that MATLAB has improved its handling of system libraries, particularly “libstdc++.so.6”.

Here is the link to one such question: https://www.mathworks.com/matlabcentral/answers/329796-issue-with-libstdc-so-6

I hope this helps!
