Hi,
I am trying to launch an executable from Matlab.
I am using Matlab 2017b and Ubuntu 16.04 and this executable file has been compiled with ubuntu too.
When I launch this file from a terminal
./myExe
it works fine but when I launch it from Matlab I get this error :
[status, out]=system('./myExe')
status = 134
out = This application failed to start because it could not find or load the Qt platform plugin "xcb".
I already looked at the answers provided here : https://fr.mathworks.com/matlabcentral/answers/272702-opening-exe-file-from-matlab-in-ubuntu-gives-error
but I have not been able to make it work.
Thank you for any help you could provide.

Try the steps below and see if they solve the issue:
1) Check whether the environment variables are the same when running from the terminal vs running from MATLAB. You can use the printenv or env commands (and use the system function to call them within MATLAB). In particular, look for the value of the PATH and LD_LIBRARY_PATH variables. Make sure that the necessary libraries on the terminal paths are available from MATLAB as well.
2) Try the following steps:
3) If you know where your QT installation is, you can try setting the following environment variable:
$ export QT_PLUGIN_PATH=<qt_base_path>/plugins

I have the similar problem which does't occur in Matlab 2017a.
The crash also happens in windows version. It seems to have relationship to image library.
But older version of 2017a is working fine.

I too have this problem. It is present with Matlab 2021a and I am using freeview from fressurfer.
