Issue with libstdc++.so.6

Dear all,

I'm running matlab r2017a on a linux Fedora 25 machine and when I tried to call an external program that required the graphical interface I got the following error.

OpenSees: /usr/local/MATLAB/R2017a/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by OpenSees)

OpenSees: /usr/local/MATLAB/R2017a/sys/os/glnxa64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by OpenSees)

When I used a built-in function of matlab I also got a similar error

Error using waitbar (line 111) Improper arguments for waitbar.

Error in selectRecords (line 8) h = waitbar(0,'Processing records');

Caused by: Error using axes Can't load '/usr/local/MATLAB/R2017a/bin/glnxa64/libmwosgserver.so': /usr/local/MATLAB/R2017a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /lib64/libGLU.so.1)

I checked using the terminal and I've got the latest version of that library installed

sudo dnf install libstdc++ Last metadata expiration check: 0:56:33 ago on Tue Mar 14 13:05:15 2017.Package libstdc++-6.3.1-1.fc25.x86_64 is already installed, skipping.Package libstdc++-6.3.1-1.fc25.i686 is already installed, skipping.Dependencies resolved.Nothing to do.Complete!

Could you please provide some guidance on how to solve this issue?

cheers L.M.

Hello,

I had a similar issue using CentOS 7 and the following solved the issue for me:

yum install compat-libstdc++-33.x86_64

Hope this helps!

Kindest Regards,

This issue might be due to an incompatibility between the libstdc++ shipped with MATLAB and the libstdc++ shipped with the system that the other application was linked against.

"CXXABI_1.3.9 not found" error message indicates that the libstdc++.so.6 library that is included with MATLAB is missing ABI versions the system needs to draw graphical content.

This is caused because the version of this particular library packaged with MATLAB is older than the versions that come with newer Linux operating systems, which causes compatibility issues.

You can try the following workarounds: 1. Renaming the libstdc++.so.6 library file so that MATLAB cannot find it and is forced to use the system's version of the library. This file is located in matlabroot/sys/os/glnxa64 . Renaming it to libstdc++.so.6.old should suffice. (where "matlabroot" is root installation directory of MATLAB)

2. Forcing MATLAB to load the system version by setting the $LD_PRELOAD environment variable to the newer version of libstdc++.

Also, since you are trying to call an external program from MATLAB, this may be a third party issue. But, you can try setting the library paths correctly in 'LD_LIBRARY_PATH' system variable.

Thank you for the feedback.

I found that calling matlab with the command LD_PRELOAD=/usr/lib64/libstdc++.so.6 matlab -desktop seems to solve the issue

in order to avoid having to type this command every time I also assigned an alias on my .bashrc file alias matlab="LD_PRELOAD=/usr/lib64/libstdc++.so.6 /usr/local/bin/matlab -desktop"

It would be nice to see Mathworks providing update packages to its software though. For example with replacements for outdated libraries.

Cheers

I had exactly the same problem as this, running Matlab r2017b on Ubuntu 16.04. The error message occurred for me when I ran the "matlab" command from the terminal, although Matlab still opened.

I found the above suggestion very useful. I needed to modify the command in my .bashrc slightly to reflect my file structure and a slightly newer library version, so I used:

alias matlab='LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21 /usr/local/bin/matlab -desktop'

In any case, the suggestion worked perfectly, thanks!

Hi, I use also use Ubuntu 16.04 and have MATLAB 2018a installed. I triedd your suggestion for the command, with a small change becuase of the file structure:

alias matlab='LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21 /usr/local/matlab -desktop'

but sadly the error still occur. Do you have some idea?

Thanks in advance!

[levi keller]

Hi Dennis: I had the same problem. type

locate libstdc++

I found that the version matlab needed was 6.0.22 and was found in

/usr/local/MATLAB/R2018a/sys/os/glnxa64/libstdc++.so.6.0.22

but it was instead loading version 6.0.21 from my /usr/lib/gcc directory

Setting

export LD_PRELOAD=/usr/local/MATLAB/R2018a/sys/os/glnxa64/libstdc++.so.6.0.22

solved the problem (temporarily)

Hi, I've tried all the solutions presented here but unfortunately the issue persists.

Does anyone have further advice?

OS: Ubuntu 16.04

MATLAB: R2018b

• Find the dynamic library libstdc ++. So.6 with "locate libstdc++". In the installation directory of matlab, for example, mine is: /usr/local/MATLAB/R2019b/sys/os/glnxa64/libstdc++.so.6.

• use the ll command. You can see: libstdc ++. So.6-> libstdc ++. So.6.0.22*

• Then rename the dynamic library, for example: sudo mv libstdc ++. So.6 libstdc ++. So.6.bak (note that sudo permission is required)

• After this operation, you can force the program to use the libstdc ++. So.6 dynamic library in the system directory.

• After re-run the program, the problem is solved

[DavyG]

Thanks BRSC User, works perfecly.

[Juan Miguel Serrano Rodríguez]

Fixed it for me on Fedora 35

[Stefan Katletz]

On Fedora 35 it was sufficient to remove the link

matlabroot/sys/os/glnxa64/libstdc++.so.6

[Orion Taylor]

renaming it to .old fixed the issue I was having! Thanks!

[Firat Soylu]

Renaming libstdc++.so.6 to libstdc++.so.6old solved it for me in MATLAB 2021B UBUNTU 20.04. Thanks!

[Lukas Heyn]

solved the problem for me in Matlab R2022b and Ubuntu 22.04, too

[cr]

This is brilliant. It worked. I had been banging my head for a day.

[Mekus Meka]

Brilliant!!

"1. Renaming the libstdc++.so.6 library file" worked fine for me.

[Maurizio]

Great - it is working for as well, after spending several days banging my head against a wall

FYI: Ubuntu 24.04 LTS and MATLAB R2025b

You need to be careful with making sure you load the correct libstdc++6.

I use it to load "brainstorm", an EEG analysis program that requires the runtime Matlab library.

On Fedora 30, I solved it just as follows:

LD_PRELOAD="/lib64/libstdc++.so.6" path_and_name_of_programme_here

Also, note that you can check whether CXXABI_1.3.9 is included simply as follows:

strings /lib64/libstdc++.so.6 | grep CXXABI

You should then see that in the text part of that library. If it shows up, it means it should work.

"import matlab.engine" should at the first line of the script.

[Ramesh Babu]

Hi,

I am still facing the same problem even after inducing the following line in .bashrc. Did I correctly entered the path in bashrc file?

   #MATLAB
    export PATH=/usr/local/MATLAB/R2017b/bin:$PATH
    export MATLABCMD=/usr/local/MATLAB/R2017b/bin/glnxa64/MATLAB
    alias matlab="LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/local/bin/matlab

When I open matlab I found the message pasted below and it opens normally.

$ matlab

/usr/local/MATLAB/R2017b/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /usr/lib/x86_64-linux-gnu/libproxy.so.1) Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/libgiolibproxy.so

I am afraid will this affect processing?

Thanks

See suggested solution above.

[Luis Rosety]

I had the same problem with Kubuntu 22.05 and the solution was what was posted in askubuntu.com:

1. Star Matlab with

matlab -softwareopengl

2. Once in Matlab, run the command

opengl('save','software')
