MATLAB 2014a (8.3) Compiler Runtime Errors libmwlaunchermain.so

matlab, matlab-compiler, ubuntu

Solution

Since I have already found a solution to this problem wasting a day, I just want to share it:

This seems to be a problem of MATLAB MCR installation script designed for Linux by MathWorks. Furthermore, it is a result of a known Ubuntu bug. To fix it, add your MCR to the `$PATH` as shown below:

First make sure to add the missing files to the right folder, in terminal:

sudo cp /usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/runtime/glnxa64/* /usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/bin/glnxa64

Add the proper library folder to your `.profile`, such that this change will stay after logout

ubuntu: gedit .profile

In the end of the file add following lines:

#MATLAB MCR

export LD_LIBRARY_PATH=/usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/bin/glnxa64
export XAPPLRESDIR=/usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/X11/app-defaults

export PATH=$PATH:$LD_LIBRARY_PATH
export PATH=$PATH:$XAPPLRESDIR

Invoke following code in the terminal to make sure that Ubuntu bug doesn't re-write your variable:

echo STARTUP=\"/usr/bin/env LD_LIBRARY_PATH=\${LD_LIBRARY_PATH} \${STARTUP}\" | sudo tee /etc/X11/Xsession.d/90preserve_ld_library_path

Reboot

If this solution doesn't work, try to reinstall MATLAB MCR 8.3 from the MathWorks website and repeat the steps.

Problem

MATLAB 2014a (8.3) Runtime Compiler (MCR) Errors when trying to launch deployed (using deploy tool) application in Ubuntu 13.04. Right after installation of MCR if one runs the deployed application following error appears: ``` error while loading shared libraries: libmwlaunchermain.so: cannot open shared object file: No such file or directory. ```
