Matlab R2022a ArchLinux installer problem fix

gistfile1.txt

I got problems installing Matlab R2022a on Arch. Running the installer throws the following error:

```
terminate called after throwing an instance of 'std::runtime_error'
  what():  Failed to launch web window with error: Unable to launch the MATLABWindow application. The exit code was: 127
fish: Job 1, 'sudo ./install' terminated by signal SIGABRT (Abort)
```

I fixed it by running the following commands.

```bash
cd <matlab installer root directory>
cd bin/glnxa64
ls | grep libfreetype
mkdir exclude
mv libfreetype.so.6 exclude/
mv libfreetype.so.6.16.0 exclude/
```

You rock!

This worked. Many thanks! (Although the installer still wouldn't start when run as super user, but I just installed it as normal user instead).
Edit: for Matlab to work correctly I had to do the same thing (moving away the libfreetype files) after I had completed the installation. Otherwise I was treated with a delightful Java nullpointer exception. The solution is also described here: https://bbs.archlinux.org/viewtopic.php?id=275084

Perfect, thank you @pgrepds!

You nailed it!

Thanks...This works

also, (currently in September 2022) version R2022b does not work on Linux (at least FOR ME), so I installed R2022a and works.

Last current version (R2022b) may not work correctly, so you can use R2022a instead. Also, for issues like: "Unable to launch the MATLABWindow application. The exit code was: 127" or "symbol lookup error: /usr/lib/libharfbuzz.so.0: undefined symbol: FT_Get_Transform" , follow this: https://wiki.archlinux.org/title/MATLAB#Unable_to_launch_the_MATLABWindow_application.

If you want to know what problems gave me R2022b, other than the "classic" symbol lookup error that is fixable, it gave to me:

"$ ./matlab
MATLAB is selecting SOFTWARE OPENGL rendering.
[allexj@Archy bin]$ terminate called after throwing an instance of 'std::runtime_error'
what(): Failed to launch web window with error: Unable to launch the MATLABWindow application. The exit code was: 1

and "$ ./glnxa64/MATLABWindow

@All3xJ For me removing libtiff* from bin/glnxa in my matlab installation fixed the error below

Thank you very much!

Thank you very much! I had the same problem but I could not find any of the .so files mentioned elsewhere. Now I finally fixed it. Thanks a lot!

thx good sir

Thank you, it helped me.

thank you very much :)

Also you need to run xhost +SI:localuser:root for the installer window to show when installing with sudo

Can confirm this also works for Fedora 36!

Do you mean cd bin/glnxa64 ? I don't think you want the path to begin /bin...

brooooooo it works.
And yes, he means cd bin/glnxa64
This is awesome i been suffering for days, thanks.

Yes, sorry. It is cd bin/glnxa64. I have corrected it. Furthermore, the command ls | grep libfreetype is obviously not necessary to fix the issue. I have just included my full "workflow" in which I have used the command to check if the files exist.

thanks bro you're huge, man

thx sirr, my prob solved

Thank you! Problem solved on Fedora36 running Kernel:6-1-14.

You saved my day! Thank you!

Thanks!

Omg, thank you! it works on fedora

These files have been finally removed by default on R2023a, now it works out of the box

Thanks, this solved the issue on Arch.
For those having problems: be sure to go to /bin/glnxa64, I was in cefclient/sys/os/glnxa64 like people in other threads suggested but this is a different (altough similar) fix.

Mine still not works... After doing that I have the exact same error, any idea to solve it?

I just spent a while to find the solution, luckily your solution works well! but I think matlab should include this in their code because I'm sure that at this moment, another person is struggling like me I did trying all the solutions at hand.
Thank you

You are genius! Thanks

Thanks. Matlab is driving me crazy. R2023b can only be launched through the terminal and it wouldn't launch by creating a desktop file. R2022b has this problem.

did you try adding -desktop argument to your .desktop file?
