What does this error mean: is:fl:file​system:Sys​temError

I get the following error when trying to compile and run a Simulink project:

Unexpected Standard exception from MEX file. What() is:fl:filesystem:SystemError

This happens after a git pull which changed the slx model and some of files which are somewhow changed in the background (.mol, .obj, ...), so I don't know exactly what changed. However the model seems to run for the person who did the changes. I can't find anything on this error here or via googling, so any idea in what direction I should look would be appreciated.

There is not enough information for me to solve this, not even a link to a git repository. Show some code if you want anyone to help you with your specific problem; we're not standing behind you, looking over your shoulder.

I think the best solution is reaching out to the person maintaining the repository and/or the person who committed the files that now cause an error.

Thanks, but I can't share the repository. I was hoping for some general hints what this kind of error message usually refers to, since I haven't found anything about that. For example - is there such a thing as "clean and rebuild" in matlab and could that help in this case?

[Rik]

As far as I understand mex (which is a basic understanding, so I may very well be wrong), the compilation is "clean and rebuild" every time it runs.

There is a similar sounding question which is a year old, without answers or comments, so contacting the dev seems to be the only way. If you're not allowed to share the repo, that's the least they can do.

I had met the same question and has it been solved? Thanks.

The attachments are my program files.

R2020b was released somewhere in the past 24 hours. The release notes mention improved git integration. Did you check it that solved your issue?

Also, nothing in your code suggests the same issue. You don't seem to be using mex or Simulink anywhere. Have a read here and here. It will greatly improve your chances of getting an answer.

Delete all the folders named 'slprj'. It may work. :D
