When trying to debug a mex file on Ubuntu 18.04 with Matlab 2018b, when I run
matlab -Dgdb
in the terminal, I get the following error:
gdb: symbol lookup error: /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0: undefined symbol: XML_SetHashSalt
I've tried to reinstall libpython3.6m.so but the problem persists. The version of gdb is 8.1.0 and works fine when launched as standalone.
How can I fix it ?

I don't know if this is a perfect solution but doing this in the current environment before `matlab -Dgdb` resolves it for me.
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libexpat.so

Hello,
Sorry I have a question. I am running a program and getting the same "undefined symbol: XML_SetHashSalt" error. I want to use the solution that you provided however I do not know where should I copy this export command that you mentioned?
I recieve the following error when I copy the export command in the MATLAB command line:
"Undefined function 'export' for input arguments of type 'char'."
Can you please help me with this error? I am using MATLAB in Ubuntu.
Thanks in advance

Running this command in the Linux shell (set as environment variable) and launch Matlab in commandline from the same shell.
