MATLAB: Segmentation violation at startup on Fedora 26

fedorasegmentation violation

I had installed successfully MATLAB 2017b on Fedora 26 about two months ago and it worked well, but now it's crashing at startup with this segment violation error.

Best Answer

This error occurs when your computer cannot load a certain font display library through MATLAB.
To resolve the issue, please navigate to MATLAB R2017b installation location in your system and remove the “libfreetype.so.6” library file shipped with MATLAB R2017b, so that MATLAB will use the system version of that library:
_matlabroot_/bin/glnxa64/
Note: Here matlabroot is the location in your system where MATLAB R2017b is installed.
Eg: ‘/usr/local/MATLAB/R2017B’
Following are the commands to execute in linux shell to perform the above mentioned operation: (You may need root privilege)
  1. cd /usr/local/MATLAB/R2017b (or wherever you may have installed MATLAB)
  2. cd bin/glnxa64
  3. mkdir exclude
  4. mv libfreetype* exclude/
Now, please start MATLAB normally. If you see any warnings on MATLAB command prompt, then please follow below link to troubleshoot:
