Why is my Matlab unable to run Simulink/MATLABWindow?

This is my error code when I am trying to start SIMULINK:

   Warning: MATLABWindow application failed to launch. Unable to launch the MATLABWindow application 
  > In sltemplate.ui.StartPage/showWithFallback
    In sltemplate.ui.StartPage.show

Referring to a similar issue that has allready been solved I tried the following:

>> cd(matlabroot)
>> ! bin/glnxa64/MATLABWindow

But I get the following error code, that has not been covered by the previously answered question:

bin/glnxa64/MATLABWindow: symbol lookup error: /usr/lib/libharfbuzz.so.0: undefined symbol: FT_Done_MM_Var

I am running Matlab R2017b on Manjaro Linux.

Hi,

I had the same issue. I am also running Matlab R2017b on Manjaro Linux with kernel 4.15.12-. This seems to solve the problem in my case:

1) Install the libselinux package from AUR

2) exclud libfreetype* files

sudo mv matlabroot/bin/glnxa64/libfreetype* exclude_path

3) run "! matlabroot/bin/glnxa64/MATLABWindow" as in simulink issues. I got the 2 error code with the proposed solution: "Set aside MATLAB’s copy of the libglib-2.0.so library, located in matlabroot/cefclient/sys/os/glnxa64".

sudo mv matlabroot/cefclient/sys/os/glnxa64/libglib-2.0.so* exclude_path

I executed "! matlabroot/bin/glnxa64/MATLABWindow" once more but the matlab terminal showed only errors. I do not recommend that ;). However, I am able to run simulink and run simulations without errors or warnings so far. Until now, everything seems to work fine :).

Best regards

This seems to solve the problem. Thank you very much. I'm not getting any warnings or errors.

Best regards

Do you mind explaining what exclude_path is? I'm using arch linux, and have the same issue. Thanks

[aleper]

The exclude_path is a path to any folder you like. For example make a new folder named "exclude" in this directory and move the files there, so you can find them in case you need to put them back in place.

excellent. It worked perfectly fine for me using arch linux. Thanks for the assistance

Windows are working now but in my case the keyboard input stopped working. Can't type anything in the log-in screen. Any clues?

#bb Can I ask how did you derive this solution? Worked for me as well on Arch Linux with Matlab R2020a
